This is driver version 1.4.4 of the Intel ixgbe driver. -It has new hardware support -It uses a new method of TX cleanup called Head Write Back -It includes the provisional generic TCP LRO feature contributed by Myricom and made general purpose by me. This should move into the stack upon approval but for this driver drop its in here. -Also bug fixes and etc... MFC in a week if no serious issues arise.

First, sync to internal shared code, and then Fixes: - flow control - don't override user value on re-init - fix to make 1G optics work correctly - change to interrupt enabling - some bits were incorrect for certain hardware. - certain stats fixes, remove a duplicate increment of ierror, thanks to Scott Long for pointing these out. - shared code link interface changed, requiring some core code changes to accomodate this. - add an m_adj() to ETHER_ALIGN on the recieve side, this was requested by Mike Karels, thanks Mike. - Multicast code corrections also thanks to Mike Karels.

Add quad port probe support, this gives the admin proper information about the slot (which should be a PCIE Gen 3 slot for this adapter) by looking back thru the PCI parent devices to the slot device. The fix above also corrects the bandwidth display to GT/s rather than the incorrect Gb/s Next, allow the use of ALTQ if you select the compile option IXGBE_LEGACY_TX. Allow the use of 'unsupported' optic modules by a compile option as well. Add a phy reset capability into the stop code, this is so a static configured driver will still behave properly when taken down (not being able to unload it). This revision synchronizes the shared code with Intel internal current code, and note that it now includes DCB supporting code, this was necessitated by some internal changes with the code, but it also will provide the opportunity to develop this feature in the core driver down the road. I have edited the README to get rid of some of the worse anachronisms in it as well, its by no means as robust as I might wish at this point however. Oh, I also have included some conditional stuff in the code so it will be compatible in both the 9.X and 10 environments. Performance has been a focus in recent changes and I believe this revision driver will perform very well in most workloads. MFC after: 2 weeks

- Add the RX refresh changes from igb to ixgbe - Also a couple minor tweaks to the TX code from the same source. - Add the INET ioctl code which has been missing from this driver, and which caused IP aliases to reset the interface. - Last, some minor logic changes that just reflect upcoming hardware support, but have no other functional effect now. MFC after a week

#include "opt_inet.h"
First off: update the driver README, the old one was horribly crusty, and this still isn't perfect, but its at least a bit more recent. Secondly, a few improvements to the driver from Andrew Boyer, support hint to allow devices to not attach, add VLAN_HWTSO capability so vlans can use TSO, fix in the interrupt handler to make sure the stack TX queue is processed. Oh, and also make sure IPv6 does not cause a re-init in the ioctl routine. Thanks for your efforts Andrew! Thanks to Claudio Jeker for noticing the ixgbe_xmit() routine was not correctly swapping the dma map from the first to the last descriptor in a multi-descriptor transmission, corrected this.

#include "opt_inet6.h"
A couple late breaking bugs that testing have turned up. - change include style so build in kernel try OR standalone work. - Limit HWCSUM - I was led to believe that it would work with RSS, but our testing had odd issues which suggests this is false. - A fatfinger error in the ioctl code made ifconfig up not work.

A number of important fixes: - mbuf reused after an RX_COPY optimized operation can sometimes have a bogus cached address, resulting in TCP hangs. Add critical save points to the cached address. Thanks to Michael and the team at Verisign for finding this problem. - A couple more spots where the rxbuf->flags member should be cleared just to be sure no incorrect RX_COPY state is left around. Thanks to Adrian for tracking these down. - Remove the rearm_queues function from the driver, this was found to be responsible for some out-of-order packets by Verisign, and was always a bandaid, with the other fixes in this delta the bandaid can finally be removed. - In the other/link interrupt handler the entire state of the EICS register was being writen back into EICR (which clears causes and thus re-enables those interrupts), this was wrong, so now mask off the queue portion of the register value, so we only clear the other/link interrupt we intend. Marc from Verisign found this. - Make the SFP+ unsupported option tuneable now, by customer request. - Finally, just a couple of minor DEBUG string fixes. I want to call out and thank all the participants in the 10G community/Intel calls for helping track down these problems and make the driver better for everyone! MFC after: 3 days, these are critical fixes for 9.2!

Additionally, the RX routine now does not refresh mbufs on every descriptor, rather it will do a range, and then update the hardware pointer at that time. These are performance oriented changes. The TX side now has a cleaner simpler watchdog algorithm as well, in TX cleanup a read of ticks is stored, that can then be compared in local_timer to determine if there is a hang.

Update the driver to Intel version 2.1.6 - add some new hardware support for 82599 - Big change to interrupt architecture, it now uses a queue which contains an RX/TX pair as the recipient of the interrupt. This will reduce overall system interrupts/msix usage. - Improved RX mbuf handling: the old get_buf routine is no longer synchronized with rxeof, this allows the elimination of packet discards due to mbuf allocation failure. - Much simplified and improved AIM code, it now happens in the queue interrupt context and takes into account both the traffic on the RX AND TX side. - variety of small tweaks, like ring size, that have been seen as performance improvements. - Thanks to those that provided feedback or suggested changes, I hope I've caught all of them.

Merge similar fixes from 223198 from igb to ixgbe: - Use a dedicated task to handle deferred transmits from the if_transmit method instead of reusing the existing per-queue interrupt task. Reusing the per-queue interrupt task could result in both an interrupt thread and the taskqueue thread trying to handle received packets on a single queue resulting in out-of-order packet processing and lock contention. - Don't define ixgbe_start() at all where if_transmit is used.

Thanks to Michael Tuexen for adding SCTP support for 82599, also for finding a one character bug that kept TSO from working. Sometimes with direct attach cables a failure can occur in init, the old method of calling detach was broken, there is no way to return an error to the system from init, so I have changed it to return failure thru the ioctl.

Update driver to Intel version 2.0.7: This adds new feature support for the 82599, a hardware assist to LRO, doing this required a large revamp to the RX cleanup code because the descriptor ring may not be processed out of order, this necessitated the elimination of global pointers. Additionally, the RX routine now does not refresh mbufs on every descriptor, rather it will do a range, and then update the hardware pointer at that time. These are performance oriented changes. The TX side now has a cleaner simpler watchdog algorithm as well, in TX cleanup a read of ticks is stored, that can then be compared in local_timer to determine if there is a hang. Various other cleanups along the way, thanks to all who have provided input and testing.

Add quad port probe support, this gives the admin proper information about the slot (which should be a PCIE Gen 3 slot for this adapter) by looking back thru the PCI parent devices to the slot device. The fix above also corrects the bandwidth display to GT/s rather than the incorrect Gb/s Next, allow the use of ALTQ if you select the compile option IXGBE_LEGACY_TX. Allow the use of 'unsupported' optic modules by a compile option as well. Add a phy reset capability into the stop code, this is so a static configured driver will still behave properly when taken down (not being able to unload it). This revision synchronizes the shared code with Intel internal current code, and note that it now includes DCB supporting code, this was necessitated by some internal changes with the code, but it also will provide the opportunity to develop this feature in the core driver down the road. I have edited the README to get rid of some of the worse anachronisms in it as well, its by no means as robust as I might wish at this point however. Oh, I also have included some conditional stuff in the code so it will be compatible in both the 9.X and 10 environments. Performance has been a focus in recent changes and I believe this revision driver will perform very well in most workloads. MFC after: 2 weeks

Patch #7 This is primarily about processing limit control. - add a limit for both RX and TX, change the default to 256 - change the sysctl usage to be common, and now to be called during init for each ring. - the TX limit is not yet used, but the changes in the last patch in this series uses the value. - the motivation behind these changes is to improve data locality in the final code. - rxeof interface changes since it now gets limit from the ring struct

Thanks to Michael Tuexen for adding SCTP support for 82599, also for finding a one character bug that kept TSO from working. Sometimes with direct attach cables a failure can occur in init, the old method of calling detach was broken, there is no way to return an error to the system from init, so I have changed it to return failure thru the ioctl. And, have fixed the ALTQ code changes of Max Laier, sorry Max :)

2008-11-26 23:41:18 +00:00
A few important fixes: - Testing TSO6 has led me to discover that HW RSC is a problematic feature, it is ONLY designed to work with IPv4 in the first place, and if IP forwarding is done it can't be disabled as LRO in the stack, also initial testing we've done at Intel shows an equal performance using TSO[46] on the TX and LRO on RX, if you ran older code on 82599 or later hardware you actually could have detrimental performance for this reason. So I am disabling the feature by default and all our adapters will now use LRO instead. - If you have flow control off and multiple queues it was possible when the buffer of one queue becomes full that all RX movement is stalled, to eliminate this problem a feature bit is now set that will allow packets to be dropped when full rather than stall. Note, the default is to have flow control on, and this keeps this from happening. - Because of the recent fixes in the stack, LRO is now auto-disabled when problematic, so I have decided to enable it by default in the capabilities in the driver. - There are some 1G modules used by some customers, a couple small tweaks to properly support those in the media code. - A note: we have now done some testing of TSO6 and using LRO with IPv6 and it all works great!! Seeing line rate in both directions in best cases. Thanks bz for your excellent work!!

Update driver to version 2.3.8: CRITICAL FIX - with stats changes the older 82598 will panic and trash the stack on driver load, FCOE registers ONLY exist in 82599 and must not be read otherwise. kern/153951 - to correct incorrect media type on adapters with pluggable modules I have eliminated the old static table in favor of a new dynamic shared code routine. This also has the benefit of detecting changes when a different module is inserted. Performance/enhancement to the Flow Director code from my linux coworker (the developer of the code). Fixes from Michael Tuexen - a data corruption problem on the 82599 (CRITICAL), fix so the buf size correctly adjusts as the cluster changes, and max descriptors are set properly. Also added 16K clusters for those REALLY big jumbos :) In the RX path, the RX LOCK was not being released, and this causes LOR problems. Add the code that igb already has. Sync with in house shared code, this was necessary for the Flow Director fix. MFC in 2 days

ixgbe changes: - remove experimental code for disabling CRC - use the correct constant for conversion between interrupt rate and EITR values (the previous values were off by a factor of 2) - make dev.ix.N.queueM.interrupt_rate a RW sysctl variable. Changing individual values affects the queue immediately, and propagates to all interfaces at the next reinit. - add dev.ix.N.queueM.irqs rdonly sysctl, to export the actual interrupt counts Netmap-related changes for ixgbe: - use the "new" format for TX descriptors in netmap mode. - pass interrupt mitigation delays to the user process doing poll() on a netmap file descriptor. On the RX side this means we will not check the ring more than once per interrupt. This gives the process a chance to sleep and process packets in larger batches, thus reducing CPU usage. On the TX side we take this even further: completed transmissions are reclaimed every half ring even if the NIC interrupts more often. This saves even more CPU without any additional tx delays. Generic Netmap-related changes: - align the netmap_kring to cache lines so that there is no false sharing (possibly useful for multiqueue NICs and MSIX interrupts, which are handled by different cores). It's a minor improvement but it does not cost anything. Reviewed by: Jack Vogel Approved by: Jack Vogel

Update driver to Intel version 2.0.7: This adds new feature support for the 82599, a hardware assist to LRO, doing this required a large revamp to the RX cleanup code because the descriptor ring may not be processed out of order, this necessitated the elimination of global pointers. Additionally, the RX routine now does not refresh mbufs on every descriptor, rather it will do a range, and then update the hardware pointer at that time. These are performance oriented changes. The TX side now has a cleaner simpler watchdog algorithm as well, in TX cleanup a read of ticks is stored, that can then be compared in local_timer to determine if there is a hang. Various other cleanups along the way, thanks to all who have provided input and testing.

Add quad port probe support, this gives the admin proper information about the slot (which should be a PCIE Gen 3 slot for this adapter) by looking back thru the PCI parent devices to the slot device. The fix above also corrects the bandwidth display to GT/s rather than the incorrect Gb/s Next, allow the use of ALTQ if you select the compile option IXGBE_LEGACY_TX. Allow the use of 'unsupported' optic modules by a compile option as well. Add a phy reset capability into the stop code, this is so a static configured driver will still behave properly when taken down (not being able to unload it). This revision synchronizes the shared code with Intel internal current code, and note that it now includes DCB supporting code, this was necessitated by some internal changes with the code, but it also will provide the opportunity to develop this feature in the core driver down the road. I have edited the README to get rid of some of the worse anachronisms in it as well, its by no means as robust as I might wish at this point however. Oh, I also have included some conditional stuff in the code so it will be compatible in both the 9.X and 10 environments.

A number of important fixes: - mbuf reused after an RX_COPY optimized operation can sometimes have a bogus cached address, resulting in TCP hangs. Add critical save points to the cached address. Thanks to Michael and the team at Verisign for finding this problem. - A couple more spots where the rxbuf->flags member should be cleared just to be sure no incorrect RX_COPY state is left around. Thanks to Adrian for tracking these down. - Remove the rearm_queues function from the driver, this was found to be responsible for some out-of-order packets by Verisign, and was always a bandaid, with the other fixes in this delta the bandaid can finally be removed. - In the other/link interrupt handler the entire state of the EICS register was being writen back into EICR (which clears causes and thus re-enables those interrupts), this was wrong, so now mask off the queue portion of the register value, so we only clear the other/link interrupt we intend. Marc from Verisign found this. - Make the SFP+ unsupported option tuneable now, by customer request. - Finally, just a couple of minor DEBUG string fixes. I want to call out and thank all the participants in the 10G community/Intel calls for helping track down these problems and make the driver better for everyone!

A few important fixes: - Testing TSO6 has led me to discover that HW RSC is a problematic feature, it is ONLY designed to work with IPv4 in the first place, and if IP forwarding is done it can't be disabled as LRO in the stack, also initial testing we've done at Intel shows an equal performance using TSO[46] on the TX and LRO on RX, if you ran older code on 82599 or later hardware you actually could have detrimental performance for this reason. So I am disabling the feature by default and all our adapters will now use LRO instead. - If you have flow control off and multiple queues it was possible when the buffer of one queue becomes full that all RX movement is stalled, to eliminate this problem a feature bit is now set that will allow packets to be dropped when full rather than stall. Note, the default is to have flow control on, and this keeps this from happening. - Because of the recent fixes in the stack, LRO is now auto-disabled when problematic, so I have decided to enable it by default in the capabilities in the driver. - There are some 1G modules used by some customers, a couple small tweaks to properly support those in the media code. - A note: we have now done some testing of TSO6 and using LRO with IPv6 and it all works great!! Seeing line rate in both directions in best cases. Thanks bz for your excellent work!!

Secondly, a few improvements to the driver from Andrew Boyer, support hint to allow devices to not attach, add VLAN_HWTSO capability so vlans can use TSO, fix in the interrupt handler to make sure the stack TX queue is processed. Oh, and also make sure IPv6 does not cause a re-init in the ioctl routine. Thanks for your efforts Andrew! Thanks to Claudio Jeker for noticing the ixgbe_xmit() routine was not correctly swapping the dma map from the first to the last descriptor in a multi-descriptor transmission, corrected this.

Update driver to version 2.3.8: CRITICAL FIX - with stats changes the older 82598 will panic and trash the stack on driver load, FCOE registers ONLY exist in 82599 and must not be read otherwise. kern/153951 - to correct incorrect media type on adapters with pluggable modules I have eliminated the old static table in favor of a new dynamic shared code routine. This also has the benefit of detecting changes when a different module is inserted. Performance/enhancement to the Flow Director code from my linux coworker (the developer of the code). Fixes from Michael Tuexen - a data corruption problem on the 82599 (CRITICAL), fix so the buf size correctly adjusts as the cluster changes, and max descriptors are set properly. Also added 16K clusters for those REALLY big jumbos :) In the RX path, the RX LOCK was not being released, and this causes LOR problems. Add the code that igb already has. Sync with in house shared code, this was necessary for the Flow Director fix. MFC in 2 days

Add quad port probe support, this gives the admin proper information about the slot (which should be a PCIE Gen 3 slot for this adapter) by looking back thru the PCI parent devices to the slot device. The fix above also corrects the bandwidth display to GT/s rather than the incorrect Gb/s Next, allow the use of ALTQ if you select the compile option IXGBE_LEGACY_TX. Allow the use of 'unsupported' optic modules by a compile option as well. Add a phy reset capability into the stop code, this is so a static configured driver will still behave properly when taken down (not being able to unload it). This revision synchronizes the shared code with Intel internal current code, and note that it now includes DCB supporting code, this was necessitated by some internal changes with the code, but it also will provide the opportunity to develop this feature in the core driver down the road. I have edited the README to get rid of some of the worse anachronisms in it as well, its by no means as robust as I might wish at this point however.

Update driver to Intel version 2.0.7: This adds new feature support for the 82599, a hardware assist to LRO, doing this required a large revamp to the RX cleanup code because the descriptor ring may not be processed out of order, this necessitated the elimination of global pointers. Additionally, the RX routine now does not refresh mbufs on every descriptor, rather it will do a range, and then update the hardware pointer at that time. These are performance oriented changes. The TX side now has a cleaner simpler watchdog algorithm as well, in TX cleanup a read of ticks is stored, that can then be compared in local_timer to determine if there is a hang.

1. Fix the handling of link reset while in netmap more. A link reset now is completely transparent for the netmap client: even if the NIC resets its own ring (e.g. restarting from 0), the client will not see any change in the current rx/tx positions, because the driver will keep track of the offset between the two. 2. make the device-specific code more uniform across different drivers There were some inconsistencies in the implementation of the netmap support routines, now drivers have been aligned to a common code structure. 3. import netmap support for ixgbe . This is implemented as a very small patch for ixgbe.c (233 lines, 11 chunks, mostly comments: in total the patch has only 54 lines of new code) , as most of the code is in an external file sys/dev/netmap/ixgbe_netmap.h , following some initial comments from Jack Vogel about making changes less intrusive. (Note, i have emailed Jack multiple times asking if he had comments on this structure of the code; i got no reply so i assume he is fine with it). Support for other drivers (em, lem, re, igb) will come later. "ixgbe" is now the reference driver for netmap support. Both the external file (sys/dev/netmap/ixgbe_netmap.h) and the device-specific patches (in sys/dev/ixgbe/ixgbe.c) are heavily commented and should serve as a reference for other device drivers. Tested on i386 and amd64 with the pkt-gen program in tools/tools/netmap, the sender does 14.88 Mpps at 1050 Mhz and 14.2 Mpps at 900 MHz on an i7-860 with 4 cores and 82599 card. Haven't tried yet more aggressive optimizations such as adding 'prefetch' instructions in the time-critical parts of the code.

Update the driver to Intel version 2.1.6 - add some new hardware support for 82599 - Big change to interrupt architecture, it now uses a queue which contains an RX/TX pair as the recipient of the interrupt. This will reduce overall system interrupts/msix usage. - Improved RX mbuf handling: the old get_buf routine is no longer synchronized with rxeof, this allows the elimination of packet discards due to mbuf allocation failure. - Much simplified and improved AIM code, it now happens in the queue interrupt context and takes into account both the traffic on the RX AND TX side. - variety of small tweaks, like ring size, that have been seen as performance improvements. - Thanks to those that provided feedback or suggested changes, I hope I've caught all of them.

Reusing the per-queue interrupt task could result in both an interrupt thread and the taskqueue thread trying to handle received packets on a single queue resulting in out-of-order packet processing and lock contention. - Don't define ixgbe_start() at all where if_transmit is used.

Patch #6 Whitespace cleanup, and removal of some very old defines (at Gleb's request). Also, change the defines around the old transmit code to IXGBE_LEGACY_TX, I do this to make it possible to define this regardless of the OS level (it is not defined by default). There are also a couple changed comments for clarity.

Update the driver to Intel version 2.1.6 - add some new hardware support for 82599 - Big change to interrupt architecture, it now uses a queue which contains an RX/TX pair as the recipient of the interrupt. This will reduce overall system interrupts/msix usage. - Improved RX mbuf handling: the old get_buf routine is no longer synchronized with rxeof, this allows the elimination of packet discards due to mbuf allocation failure. - Much simplified and improved AIM code, it now happens in the queue interrupt context and takes into account both the traffic on the RX AND TX side. - variety of small tweaks, like ring size, that have been seen as performance improvements. - Thanks to those that provided feedback or suggested changes, I hope I've caught all of them.

Merge similar fixes from 223198 from igb to ixgbe: - Use a dedicated task to handle deferred transmits from the if_transmit method instead of reusing the existing per-queue interrupt task. Reusing the per-queue interrupt task could result in both an interrupt thread and the taskqueue thread trying to handle received packets on a single queue resulting in out-of-order packet processing and lock contention. - Don't define ixgbe_start() at all where if_transmit is used.

This fixes a out-of-order problem with several of the newer drivers. The basic problem was that the driver was pulling the mbuf off the drbr ring and then when sending with xmit(), encounting a full transmit ring. Thus the lower layer xmit() function would return an error, and the drivers would then append the data back on to the ring. For TCP this is a horrible scenario sure to bring on a fast-retransmit. The fix is to use drbr_peek() to pull the data pointer but not remove it from the ring. If it fails then we either call the new drbr_putback or drbr_advance method. Advance moves it forward (we do this sometimes when the xmit() function frees the mbuf). When we succeed we always call advance. The putback will always copy the mbuf back to the top of the ring. Note that the putback *cannot* be used with a drbr_dequeue() only with drbr_peek(). We most of the time, in putback, would not need to copy it back since most likey the mbuf is still the same, but sometimes xmit() functions will change the mbuf via a pullup or other call. So the optimial case for the single consumer is to always copy it back. If we ever do a multiple_consumer (for lagg?) we will need a test and atomic in the put back possibly a seperate putback_mc() in the ring buf. Reviewed by: jhb@freebsd.org, jlv@freebsd.org

Update driver to Intel version 2.0.7: This adds new feature support for the 82599, a hardware assist to LRO, doing this required a large revamp to the RX cleanup code because the descriptor ring may not be processed out of order, this necessitated the elimination of global pointers. Additionally, the RX routine now does not refresh mbufs on every descriptor, rather it will do a range, and then update the hardware pointer at that time. These are performance oriented changes. The TX side now has a cleaner simpler watchdog algorithm as well, in TX cleanup a read of ticks is stored, that can then be compared in local_timer to determine if there is a hang. Various other cleanups along the way, thanks to all who have provided input and testing.

I have edited the README to get rid of some of the worse anachronisms in it as well, its by no means as robust as I might wish at this point however.

Update the driver to Intel version 2.1.6 - add some new hardware support for 82599 - Big change to interrupt architecture, it now uses a queue which contains an RX/TX pair as the recipient of the interrupt. This will reduce overall system interrupts/msix usage. - Improved RX mbuf handling: the old get_buf routine is no longer synchronized with rxeof, this allows the elimination of packet discards due to mbuf allocation failure. - Much simplified and improved AIM code, it now happens in the queue interrupt context and takes into account both the traffic on the RX AND TX side. - variety of small tweaks, like ring size, that have been seen as performance improvements. - Thanks to those that provided feedback or suggested changes, I hope I've caught all of them.

First off: update the driver README, the old one was horribly crusty, and this still isn't perfect, but its at least a bit more recent. Secondly, a few improvements to the driver from Andrew Boyer, support hint to allow devices to not attach, add VLAN_HWTSO capability so vlans can use TSO, fix in the interrupt handler to make sure the stack TX queue is processed. Oh, and also make sure IPv6 does not cause a re-init in the ioctl routine. Thanks for your efforts Andrew! Thanks to Claudio Jeker for noticing the ixgbe_xmit() routine was not correctly swapping the dma map from the first to the last descriptor in a multi-descriptor transmission, corrected this.

Update driver to Intel version 2.0.7: This adds new feature support for the 82599, a hardware assist to LRO, doing this required a large revamp to the RX cleanup code because the descriptor ring may not be processed out of order, this necessitated the elimination of global pointers. Additionally, the RX routine now does not refresh mbufs on every descriptor, rather it will do a range, and then update the hardware pointer at that time. These are performance oriented changes. The TX side now has a cleaner simpler watchdog algorithm as well, in TX cleanup a read of ticks is stored, that can then be compared in local_timer to determine if there is a hang. Various other cleanups along the way, thanks to all who have provided input and testing.

First off: update the driver README, the old one was horribly crusty, and this still isn't perfect, but its at least a bit more recent. Secondly, a few improvements to the driver from Andrew Boyer, support hint to allow devices to not attach, add VLAN_HWTSO capability so vlans can use TSO, fix in the interrupt handler to make sure the stack TX queue is processed. Oh, and also make sure IPv6 does not cause a re-init in the ioctl routine. Thanks for your efforts Andrew! Thanks to Claudio Jeker for noticing the ixgbe_xmit() routine was not correctly swapping the dma map from the first to the last descriptor in a multi-descriptor transmission, corrected this.

Thanks to Michael Tuexen for adding SCTP support for 82599, also for finding a one character bug that kept TSO from working. Sometimes with direct attach cables a failure can occur in init, the old method of calling detach was broken, there is no way to return an error to the system from init, so I have changed it to return failure thru the ioctl. And, have fixed the ALTQ code changes of Max Laier, sorry Max :)

A number of important fixes: - mbuf reused after an RX_COPY optimized operation can sometimes have a bogus cached address, resulting in TCP hangs. Add critical save points to the cached address. Thanks to Michael and the team at Verisign for finding this problem. - A couple more spots where the rxbuf->flags member should be cleared just to be sure no incorrect RX_COPY state is left around. Thanks to Adrian for tracking these down. - Remove the rearm_queues function from the driver, this was found to be responsible for some out-of-order packets by Verisign, and was always a bandaid, with the other fixes in this delta the bandaid can finally be removed. - In the other/link interrupt handler the entire state of the EICS register was being writen back into EICR (which clears causes and thus re-enables those interrupts), this was wrong, so now mask off the queue portion of the register value, so we only clear the other/link interrupt we intend. Marc from Verisign found this. - Make the SFP+ unsupported option tuneable now, by customer request. - Finally, just a couple of minor DEBUG string fixes. I want to call out and thank all the participants in the 10G community/Intel calls for helping track down these problems and make the driver better for everyone!

Update driver to Intel version 2.0.7: This adds new feature support for the 82599, a hardware assist to LRO, doing this required a large revamp to the RX cleanup code because the descriptor ring may not be processed out of order, this necessitated the elimination of global pointers. Additionally, the RX routine now does not refresh mbufs on every descriptor, rather it will do a range, and then update the hardware pointer at that time. These are performance oriented changes. The TX side now has a cleaner simpler watchdog algorithm as well, in TX cleanup a read of ticks is stored, that can then be compared in local_timer to determine if there is a hang. Various other cleanups along the way, thanks to all who have provided input and testing.

Update driver to Intel version 2.0.7: This adds new feature support for the 82599, a hardware assist to LRO, doing this required a large revamp to the RX cleanup code because the descriptor ring may not be processed out of order, this necessitated the elimination of global pointers. Additionally, the RX routine now does not refresh mbufs on every descriptor, rather it will do a range, and then update the hardware pointer at that time. These are performance oriented changes. The TX side now has a cleaner simpler watchdog algorithm as well, in TX cleanup a read of ticks is stored, that can then be compared in local_timer to determine if there is a hang. Various other cleanups along the way, thanks to all who have provided input and testing.

Enable prefetching of descriptors on the TX ring, using the same values as in the Intel driver 3.8.21 for linux. The fact that it is standard in the above driver suggests that it has no bad side effects. But of course there must be a reason for enabling features, not just "it does not harm", so here it is a good one: Prefetching enables full line rate even using a single queue (14.88 Mpps, compared to ~12 Mpps without prefetch). This in turn is terribly useful when one wants to schedule traffic. For obvious reasons the difference is only visible with netmap or other high speed solutions, but presumably the advantage should be in the order of a fraction of a microsecond when starting transmission on an empty queue. Discussed with Jack Vogel. MFC after: 1 week

netmap-related changes: 1. correct the initialization of RDT when there is an ixgbe_init() while a netmap client is active. This code was previously in ixgbe_initialize_receive_units() but RDT is overwritten shortly afterwards in ixgbe_init_locked() 2. add code (not active yet) to disable CRCSTRIP while in netmap mode. From all evidence i could gather, it seems that when the 82599 has to write a data block that is not a full cache line, it first reads the line (64 bytes) and then writes back the updated version. This hurts reception of min-sized frames, which are only 60 bytes if the CRC is stripped: i could never get above 11Mpps (received from one queue) with CRCSTRIP enabled, whyle 64+4-byte packets reach 14.2 Mpps (the theoretical maximum). Leaving the CRC in gets us 14.88Mpps for 60+4 byte frames, (and penalizes 64+4). The min-size case is important not just because it looks good in benchmarks, but also because this is the size of pure acks. Note we cannot leave CRCSTRIP on by default because it is incompatible with some other features (LRO etc.)

First, sync to internal shared code, and then Fixes: - flow control - don't override user value on re-init - fix to make 1G optics work correctly - change to interrupt enabling - some bits were incorrect for certain hardware. - certain stats fixes, remove a duplicate increment of ierror, thanks to Scott Long for pointing these out. - shared code link interface changed, requiring some core code changes to accomodate this. - add an m_adj() to ETHER_ALIGN on the recieve side, this was requested by Mike Karels, thanks Mike. - Multicast code corrections also thanks to Mike Karels.

Update driver to Intel version 2.0.7: This adds new feature support for the 82599, a hardware assist to LRO, doing this required a large revamp to the RX cleanup code because the descriptor ring may not be processed out of order, this necessitated the elimination of global pointers. Additionally, the RX routine now does not refresh mbufs on every descriptor, rather it will do a range, and then update the hardware pointer at that time. These are performance oriented changes. The TX side now has a cleaner simpler watchdog algorithm as well, in TX cleanup a read of ticks is stored, that can then be compared in local_timer to determine if there is a hang. Various other cleanups along the way, thanks to all who have provided input and testing.

Update the driver to Intel version 2.1.6 - add some new hardware support for 82599 - Big change to interrupt architecture, it now uses a queue which contains an RX/TX pair as the recipient of the interrupt. This will reduce overall system interrupts/msix usage. - Improved RX mbuf handling: the old get_buf routine is no longer synchronized with rxeof, this allows the elimination of packet discards due to mbuf allocation failure. - Much simplified and improved AIM code, it now happens in the queue interrupt context and takes into account both the traffic on the RX AND TX side. - variety of small tweaks, like ring size, that have been seen as performance improvements. - Thanks to those that provided feedback or suggested changes, I hope I've caught all of them.

This is an update to the new Intel 10G 82598 driver. The first drop was Beta, this code is expected to be the release version. Note that this driver code will build in either 6.2 or 7. If you use the code in 6.2 you will not get TSO or MSI/X support but it will function in a legacy mode. Approved by: re

Update the driver to Intel version 2.1.6 - add some new hardware support for 82599 - Big change to interrupt architecture, it now uses a queue which contains an RX/TX pair as the recipient of the interrupt. This will reduce overall system interrupts/msix usage. - Improved RX mbuf handling: the old get_buf routine is no longer synchronized with rxeof, this allows the elimination of packet discards due to mbuf allocation failure. - Much simplified and improved AIM code, it now happens in the queue interrupt context and takes into account both the traffic on the RX AND TX side. - variety of small tweaks, like ring size, that have been seen as performance improvements. - Thanks to those that provided feedback or suggested changes, I hope I've caught all of them.

Add quad port probe support, this gives the admin proper information about the slot (which should be a PCIE Gen 3 slot for this adapter) by looking back thru the PCI parent devices to the slot device. The fix above also corrects the bandwidth display to GT/s rather than the incorrect Gb/s Next, allow the use of ALTQ if you select the compile option IXGBE_LEGACY_TX. Allow the use of 'unsupported' optic modules by a compile option as well. Add a phy reset capability into the stop code, this is so a static configured driver will still behave properly when taken down (not being able to unload it). This revision synchronizes the shared code with Intel internal current code, and note that it now includes DCB supporting code, this was necessitated by some internal changes with the code, but it also will provide the opportunity to develop this feature in the core driver down the road. I have edited the README to get rid of some of the worse anachronisms in it as well, its by no means as robust as I might wish at this point however. Oh, I also have included some conditional stuff in the code so it will be compatible in both the 9.X and 10 environments.

First off: update the driver README, the old one was horribly crusty, and this still isn't perfect, but its at least a bit more recent. Secondly, a few improvements to the driver from Andrew Boyer, support hint to allow devices to not attach, add VLAN_HWTSO capability so vlans can use TSO, fix in the interrupt handler to make sure the stack TX queue is processed. Oh, and also make sure IPv6 does not cause a re-init in the ioctl routine. Thanks for your efforts Andrew! Thanks to Claudio Jeker for noticing the ixgbe_xmit() routine was not correctly swapping the dma map from the first to the last descriptor in a multi-descriptor transmission, corrected this.

A number of important fixes: - mbuf reused after an RX_COPY optimized operation can sometimes have a bogus cached address, resulting in TCP hangs. Add critical save points to the cached address. Thanks to Michael and the team at Verisign for finding this problem. - A couple more spots where the rxbuf->flags member should be cleared just to be sure no incorrect RX_COPY state is left around. Thanks to Adrian for tracking these down. - Remove the rearm_queues function from the driver, this was found to be responsible for some out-of-order packets by Verisign, and was always a bandaid, with the other fixes in this delta the bandaid can finally be removed. - In the other/link interrupt handler the entire state of the EICS register was being writen back into EICR (which clears causes and thus re-enables those interrupts), this was wrong, so now mask off the queue portion of the register value, so we only clear the other/link interrupt we intend. Marc from Verisign found this. - Make the SFP+ unsupported option tuneable now, by customer request. - Finally, just a couple of minor DEBUG string fixes. I want to call out and thank all the participants in the 10G community/Intel calls for helping track down these problems and make the driver better for everyone! MFC after: 3 days, these are critical fixes for 9.2!

The fix above also corrects the bandwidth display to GT/s rather than the incorrect Gb/s Next, allow the use of ALTQ if you select the compile option IXGBE_LEGACY_TX. Allow the use of 'unsupported' optic modules by a compile option as well. Add a phy reset capability into the stop code, this is so a static configured driver will still behave properly when taken down (not being able to unload it). This revision synchronizes the shared code with Intel internal current code, and note that it now includes DCB supporting code, this was necessitated by some internal changes with the code, but it also will provide the opportunity to develop this feature in the core driver down the road. I have edited the README to get rid of some of the worse anachronisms in it as well, its by no means as robust as I might wish at this point however. Oh, I also have included some conditional stuff in the code so it will be compatible in both the 9.X and 10 environments. Performance has been a focus in recent changes and I believe this revision driver will perform very well in most workloads. MFC after: 2 weeks

Update the driver to Intel version 2.1.6 - add some new hardware support for 82599 - Big change to interrupt architecture, it now uses a queue which contains an RX/TX pair as the recipient of the interrupt. This will reduce overall system interrupts/msix usage. - Improved RX mbuf handling: the old get_buf routine is no longer synchronized with rxeof, this allows the elimination of packet discards due to mbuf allocation failure. - Much simplified and improved AIM code, it now happens in the queue interrupt context and takes into account both the traffic on the RX AND TX side. - variety of small tweaks, like ring size, that have been seen as performance improvements. - Thanks to those that provided feedback or suggested changes, I hope I've caught all of them.

A number of important fixes: - mbuf reused after an RX_COPY optimized operation can sometimes have a bogus cached address, resulting in TCP hangs. Add critical save points to the cached address. Thanks to Michael and the team at Verisign for finding this problem. - A couple more spots where the rxbuf->flags member should be cleared just to be sure no incorrect RX_COPY state is left around. Thanks to Adrian for tracking these down. - Remove the rearm_queues function from the driver, this was found to be responsible for some out-of-order packets by Verisign, and was always a bandaid, with the other fixes in this delta the bandaid can finally be removed. - In the other/link interrupt handler the entire state of the EICS register was being writen back into EICR (which clears causes and thus re-enables those interrupts), this was wrong, so now mask off the queue portion of the register value, so we only clear the other/link interrupt we intend. Marc from Verisign found this. - Make the SFP+ unsupported option tuneable now, by customer request. - Finally, just a couple of minor DEBUG string fixes. I want to call out and thank all the participants in the 10G community/Intel calls for helping track down these problems and make the driver better for everyone!

Update driver to version 2.3.8: CRITICAL FIX - with stats changes the older 82598 will panic and trash the stack on driver load, FCOE registers ONLY exist in 82599 and must not be read otherwise. kern/153951 - to correct incorrect media type on adapters with pluggable modules I have eliminated the old static table in favor of a new dynamic shared code routine. This also has the benefit of detecting changes when a different module is inserted. Performance/enhancement to the Flow Director code from my linux coworker (the developer of the code). Fixes from Michael Tuexen - a data corruption problem on the 82599 (CRITICAL), fix so the buf size correctly adjusts as the cluster changes, and max descriptors are set properly. Also added 16K clusters for those REALLY big jumbos :) In the RX path, the RX LOCK was not being released, and this causes LOR problems. Add the code that igb already has.

First off: update the driver README, the old one was horribly crusty, and this still isn't perfect, but its at least a bit more recent. Secondly, a few improvements to the driver from Andrew Boyer, support hint to allow devices to not attach, add VLAN_HWTSO capability so vlans can use TSO, fix in the interrupt handler to make sure the stack TX queue is processed. Oh, and also make sure IPv6 does not cause a re-init in the ioctl routine. Thanks for your efforts Andrew! Thanks to Claudio Jeker for noticing the ixgbe_xmit() routine was not correctly swapping the dma map from the first to the last descriptor in a multi-descriptor transmission, corrected this.

Update driver to Intel version 2.0.7: This adds new feature support for the 82599, a hardware assist to LRO, doing this required a large revamp to the RX cleanup code because the descriptor ring may not be processed out of order, this necessitated the elimination of global pointers. Additionally, the RX routine now does not refresh mbufs on every descriptor, rather it will do a range, and then update the hardware pointer at that time. These are performance oriented changes. The TX side now has a cleaner simpler watchdog algorithm as well, in TX cleanup a read of ticks is stored, that can then be compared in local_timer to determine if there is a hang.

Update the driver to Intel version 2.1.6 - add some new hardware support for 82599 - Big change to interrupt architecture, it now uses a queue which contains an RX/TX pair as the recipient of the interrupt. This will reduce overall system interrupts/msix usage. - Improved RX mbuf handling: the old get_buf routine is no longer synchronized with rxeof, this allows the elimination of packet discards due to mbuf allocation failure. - Much simplified and improved AIM code, it now happens in the queue interrupt context and takes into account both the traffic on the RX AND TX side. - variety of small tweaks, like ring size, that have been seen as performance improvements. - Thanks to those that provided feedback or suggested changes, I hope I've caught all of them.

First off: update the driver README, the old one was horribly crusty, and this still isn't perfect, but its at least a bit more recent. Secondly, a few improvements to the driver from Andrew Boyer, support hint to allow devices to not attach, add VLAN_HWTSO capability so vlans can use TSO, fix in the interrupt handler to make sure the stack TX queue is processed. Oh, and also make sure IPv6 does not cause a re-init in the ioctl routine. Thanks for your efforts Andrew! Thanks to Claudio Jeker for noticing the ixgbe_xmit() routine was not correctly swapping the dma map from the first to the last descriptor in a multi-descriptor transmission, corrected this.

Update the driver to Intel version 2.1.6 - add some new hardware support for 82599 - Big change to interrupt architecture, it now uses a queue which contains an RX/TX pair as the recipient of the interrupt. This will reduce overall system interrupts/msix usage. - Improved RX mbuf handling: the old get_buf routine is no longer synchronized with rxeof, this allows the elimination of packet discards due to mbuf allocation failure. - Much simplified and improved AIM code, it now happens in the queue interrupt context and takes into account both the traffic on the RX AND TX side. - variety of small tweaks, like ring size, that have been seen as performance improvements. - Thanks to those that provided feedback or suggested changes, I hope I've caught all of them.

Update driver to version 2.3.8: CRITICAL FIX - with stats changes the older 82598 will panic and trash the stack on driver load, FCOE registers ONLY exist in 82599 and must not be read otherwise. kern/153951 - to correct incorrect media type on adapters with pluggable modules I have eliminated the old static table in favor of a new dynamic shared code routine. This also has the benefit of detecting changes when a different module is inserted. Performance/enhancement to the Flow Director code from my linux coworker (the developer of the code).

A few important fixes: - Testing TSO6 has led me to discover that HW RSC is a problematic feature, it is ONLY designed to work with IPv4 in the first place, and if IP forwarding is done it can't be disabled as LRO in the stack, also initial testing we've done at Intel shows an equal performance using TSO[46] on the TX and LRO on RX, if you ran older code on 82599 or later hardware you actually could have detrimental performance for this reason. So I am disabling the feature by default and all our adapters will now use LRO instead. - If you have flow control off and multiple queues it was possible when the buffer of one queue becomes full that all RX movement is stalled, to eliminate this problem a feature bit is now set that will allow packets to be dropped when full rather than stall. Note, the default is to have flow control on, and this keeps this from happening. - Because of the recent fixes in the stack, LRO is now auto-disabled when problematic, so I have decided to enable it by default in the capabilities in the driver. - There are some 1G modules used by some customers, a couple small tweaks to properly support those in the media code. - A note: we have now done some testing of TSO6 and using LRO with IPv6 and it all works great!! Seeing line rate in both directions in best cases. Thanks bz for your excellent work!!

Update driver to Intel version 2.0.7: This adds new feature support for the 82599, a hardware assist to LRO, doing this required a large revamp to the RX cleanup code because the descriptor ring may not be processed out of order, this necessitated the elimination of global pointers. Additionally, the RX routine now does not refresh mbufs on every descriptor, rather it will do a range, and then update the hardware pointer at that time. These are performance oriented changes. The TX side now has a cleaner simpler watchdog algorithm as well, in TX cleanup a read of ticks is stored, that can then be compared in local_timer to determine if there is a hang. Various other cleanups along the way, thanks to all who have provided input and testing.

Remove the sysctl process_limit interface, after some thought I've decided its overkill,a simple tuneable for each RX and TX limit, and then init sets the ring values based on that, should be sufficient.

Merge similar fixes from 223198 from igb to ixgbe: - Use a dedicated task to handle deferred transmits from the if_transmit method instead of reusing the existing per-queue interrupt task. Reusing the per-queue interrupt task could result in both an interrupt thread and the taskqueue thread trying to handle received packets on a single queue resulting in out-of-order packet processing and lock contention. - Don't define ixgbe_start() at all where if_transmit is used.

Update driver to Intel version 2.0.7: This adds new feature support for the 82599, a hardware assist to LRO, doing this required a large revamp to the RX cleanup code because the descriptor ring may not be processed out of order, this necessitated the elimination of global pointers. Additionally, the RX routine now does not refresh mbufs on every descriptor, rather it will do a range, and then update the hardware pointer at that time. These are performance oriented changes. The TX side now has a cleaner simpler watchdog algorithm as well, in TX cleanup a read of ticks is stored, that can then be compared in local_timer to determine if there is a hang. Various other cleanups along the way, thanks to all who have provided input and testing.

Update driver to version 2.3.8: CRITICAL FIX - with stats changes the older 82598 will panic and trash the stack on driver load, FCOE registers ONLY exist in 82599 and must not be read otherwise. kern/153951 - to correct incorrect media type on adapters with pluggable modules I have eliminated the old static table in favor of a new dynamic shared code routine. This also has the benefit of detecting changes when a different module is inserted. Performance/enhancement to the Flow Director code from my linux coworker (the developer of the code). Fixes from Michael Tuexen - a data corruption problem on the 82599 (CRITICAL), fix so the buf size correctly adjusts as the cluster changes, and max descriptors are set properly. Also added 16K clusters for those REALLY big jumbos :) In the RX path, the RX LOCK was not being released, and this causes LOR problems. Add the code that igb already has.

First off: update the driver README, the old one was horribly crusty, and this still isn't perfect, but its at least a bit more recent. Secondly, a few improvements to the driver from Andrew Boyer, support hint to allow devices to not attach, add VLAN_HWTSO capability so vlans can use TSO, fix in the interrupt handler to make sure the stack TX queue is processed. Oh, and also make sure IPv6 does not cause a re-init in the ioctl routine. Thanks for your efforts Andrew! Thanks to Claudio Jeker for noticing the ixgbe_xmit() routine was not correctly swapping the dma map from the first to the last descriptor in a multi-descriptor transmission, corrected this.

Update driver to Intel version 2.0.7: This adds new feature support for the 82599, a hardware assist to LRO, doing this required a large revamp to the RX cleanup code because the descriptor ring may not be processed out of order, this necessitated the elimination of global pointers. Additionally, the RX routine now does not refresh mbufs on every descriptor, rather it will do a range, and then update the hardware pointer at that time. These are performance oriented changes. The TX side now has a cleaner simpler watchdog algorithm as well, in TX cleanup a read of ticks is stored, that can then be compared in local_timer to determine if there is a hang. Various other cleanups along the way, thanks to all who have provided input and testing.

Add quad port probe support, this gives the admin proper information about the slot (which should be a PCIE Gen 3 slot for this adapter) by looking back thru the PCI parent devices to the slot device. The fix above also corrects the bandwidth display to GT/s rather than the incorrect Gb/s Next, allow the use of ALTQ if you select the compile option IXGBE_LEGACY_TX. Allow the use of 'unsupported' optic modules by a compile option as well.

This revision synchronizes the shared code with Intel internal current code, and note that it now includes DCB supporting code, this was necessitated by some internal changes with the code, but it also will provide the opportunity to develop this feature in the core driver down the road.

Merge similar fixes from 223198 from igb to ixgbe: - Use a dedicated task to handle deferred transmits from the if_transmit method instead of reusing the existing per-queue interrupt task. Reusing the per-queue interrupt task could result in both an interrupt thread and the taskqueue thread trying to handle received packets on a single queue resulting in out-of-order packet processing and lock contention. - Don't define ixgbe_start() at all where if_transmit is used.

Update ixgbe driver to verion 2.3.6 - This adds a VM SRIOV interface, ixv, it is however transparent to the user, it links with the ixgbe.ko, but when ixgbe is loaded in a virtualized guest with SRIOV configured this will be detected. - Sync shared code to latest - Many bug fixes and improvements, thanks to everyone who has been using the driver and reporting issues.

A few important fixes: - Testing TSO6 has led me to discover that HW RSC is a problematic feature, it is ONLY designed to work with IPv4 in the first place, and if IP forwarding is done it can't be disabled as LRO in the stack, also initial testing we've done at Intel shows an equal performance using TSO[46] on the TX and LRO on RX, if you ran older code on 82599 or later hardware you actually could have detrimental performance for this reason. So I am disabling the feature by default and all our adapters will now use LRO instead. - If you have flow control off and multiple queues it was possible when the buffer of one queue becomes full that all RX movement is stalled, to eliminate this problem a feature bit is now set that will allow packets to be dropped when full rather than stall. Note, the default is to have flow control on, and this keeps this from happening. - Because of the recent fixes in the stack, LRO is now auto-disabled when problematic, so I have decided to enable it by default in the capabilities in the driver. - There are some 1G modules used by some customers, a couple small tweaks to properly support those in the media code. - A note: we have now done some testing of TSO6 and using LRO with IPv6 and it all works great!! Seeing line rate in both directions in best cases. Thanks bz for your excellent work!!

First off: update the driver README, the old one was horribly crusty, and this still isn't perfect, but its at least a bit more recent. Secondly, a few improvements to the driver from Andrew Boyer, support hint to allow devices to not attach, add VLAN_HWTSO capability so vlans can use TSO, fix in the interrupt handler to make sure the stack TX queue is processed. Oh, and also make sure IPv6 does not cause a re-init in the ioctl routine. Thanks for your efforts Andrew! Thanks to Claudio Jeker for noticing the ixgbe_xmit() routine was not correctly swapping the dma map from the first to the last descriptor in a multi-descriptor transmission, corrected this.

Update driver to version 2.3.8: CRITICAL FIX - with stats changes the older 82598 will panic and trash the stack on driver load, FCOE registers ONLY exist in 82599 and must not be read otherwise. kern/153951 - to correct incorrect media type on adapters with pluggable modules I have eliminated the old static table in favor of a new dynamic shared code routine. This also has the benefit of detecting changes when a different module is inserted. Performance/enhancement to the Flow Director code from my linux coworker (the developer of the code). Fixes from Michael Tuexen - a data corruption problem on the 82599 (CRITICAL), fix so the buf size correctly adjusts as the cluster changes, and max descriptors are set properly. Also added 16K clusters for those REALLY big jumbos :) In the RX path, the RX LOCK was not being released, and this causes LOR problems. Add the code that igb already has. Sync with in house shared code, this was necessary for the Flow Director fix. MFC in 2 days

Update driver to Intel version 2.0.7: This adds new feature support for the 82599, a hardware assist to LRO, doing this required a large revamp to the RX cleanup code because the descriptor ring may not be processed out of order, this necessitated the elimination of global pointers. Additionally, the RX routine now does not refresh mbufs on every descriptor, rather it will do a range, and then update the hardware pointer at that time. These are performance oriented changes. The TX side now has a cleaner simpler watchdog algorithm as well, in TX cleanup a read of ticks is stored, that can then be compared in local_timer to determine if there is a hang.

Update driver to version 2.3.8: CRITICAL FIX - with stats changes the older 82598 will panic and trash the stack on driver load, FCOE registers ONLY exist in 82599 and must not be read otherwise. kern/153951 - to correct incorrect media type on adapters with pluggable modules I have eliminated the old static table in favor of a new dynamic shared code routine. This also has the benefit of detecting changes when a different module is inserted. Performance/enhancement to the Flow Director code from my linux coworker (the developer of the code). Fixes from Michael Tuexen - a data corruption problem on the 82599 (CRITICAL), fix so the buf size correctly adjusts as the cluster changes, and max descriptors are set properly. Also added 16K clusters for those REALLY big jumbos :) In the RX path, the RX LOCK was not being released, and this causes LOR problems. Add the code that igb already has. Sync with in house shared code, this was necessary for the Flow Director fix. MFC in 2 days

Update driver to Intel version 2.0.7: This adds new feature support for the 82599, a hardware assist to LRO, doing this required a large revamp to the RX cleanup code because the descriptor ring may not be processed out of order, this necessitated the elimination of global pointers. Additionally, the RX routine now does not refresh mbufs on every descriptor, rather it will do a range, and then update the hardware pointer at that time. These are performance oriented changes. The TX side now has a cleaner simpler watchdog algorithm as well, in TX cleanup a read of ticks is stored, that can then be compared in local_timer to determine if there is a hang. Various other cleanups along the way, thanks to all who have provided input and testing.

The two changes above unfortunately require an API change, so while at it add a version field and some spares to the ioctl() argument to help detect mismatches. 4. update the manual page for the two changes above; 5. update sample applications in tools/tools/netmap KERNEL: 1. simplify the internal structures moving the global wait queues to the 'struct netmap_adapter'; 2. simplify the functions that map kring<->nic ring indexes 3. normalize device-specific code, helps mainteinance; 4. start exploring the impact of micro-optimizations (prefetch etc.) in the ixgbe driver. Use 'legacy' descriptors on the tx ring and prefetch slots gives about 20% speedup at 900 MHz. Another 7-10% would come from removing the explict calls to bus_dmamap* in the core (they are effectively NOPs in this case, but it takes expensive load of the per-buffer dma maps to figure out that they are all NULL. Rx performance not investigated. I am postponing the MFC so i can import a few more improvements before merging.

* netmap_idx_n2k() handles wraparounds properly.
1. Fix the handling of link reset while in netmap more. A link reset now is completely transparent for the netmap client: even if the NIC resets its own ring (e.g. restarting from 0), the client will not see any change in the current rx/tx positions, because the driver will keep track of the offset between the two. 2. make the device-specific code more uniform across different drivers There were some inconsistencies in the implementation of the netmap support routines, now drivers have been aligned to a common code structure. 3. import netmap support for ixgbe . This is implemented as a very small patch for ixgbe.c (233 lines, 11 chunks, mostly comments: in total the patch has only 54 lines of new code) , as most of the code is in an external file sys/dev/netmap/ixgbe_netmap.h , following some initial comments from Jack Vogel about making changes less intrusive. (Note, i have emailed Jack multiple times asking if he had comments on this structure of the code; i got no reply so i assume he is fine with it). Support for other drivers (em, lem, re, igb) will come later. "ixgbe" is now the reference driver for netmap support. Both the external file (sys/dev/netmap/ixgbe_netmap.h) and the device-specific patches (in sys/dev/ixgbe/ixgbe.c) are heavily commented and should serve as a reference for other device drivers. Tested on i386 and amd64 with the pkt-gen program in tools/tools/netmap, the sender does 14.88 Mpps at 1050 Mhz and 14.2 Mpps at 900 MHz on an i7-860 with 4 cores and 82599 card. Haven't tried yet more aggressive optimizations such as adding 'prefetch' instructions in the time-critical parts of the code.

Update driver to Intel version 2.0.7: This adds new feature support for the 82599, a hardware assist to LRO, doing this required a large revamp to the RX cleanup code because the descriptor ring may not be processed out of order, this necessitated the elimination of global pointers. Additionally, the RX routine now does not refresh mbufs on every descriptor, rather it will do a range, and then update the hardware pointer at that time. These are performance oriented changes. The TX side now has a cleaner simpler watchdog algorithm as well, in TX cleanup a read of ticks is stored, that can then be compared in local_timer to determine if there is a hang. Various other cleanups along the way, thanks to all who have provided input and testing.

Update the driver to Intel version 2.1.6 - add some new hardware support for 82599 - Big change to interrupt architecture, it now uses a queue which contains an RX/TX pair as the recipient of the interrupt. This will reduce overall system interrupts/msix usage. - Improved RX mbuf handling: the old get_buf routine is no longer synchronized with rxeof, this allows the elimination of packet discards due to mbuf allocation failure. - Much simplified and improved AIM code, it now happens in the queue interrupt context and takes into account both the traffic on the RX AND TX side. - variety of small tweaks, like ring size, that have been seen as performance improvements. - Thanks to those that provided feedback or suggested changes, I hope I've caught all of them.

A number of important fixes: - mbuf reused after an RX_COPY optimized operation can sometimes have a bogus cached address, resulting in TCP hangs. Add critical save points to the cached address. Thanks to Michael and the team at Verisign for finding this problem. - A couple more spots where the rxbuf->flags member should be cleared just to be sure no incorrect RX_COPY state is left around. Thanks to Adrian for tracking these down. - Remove the rearm_queues function from the driver, this was found to be responsible for some out-of-order packets by Verisign, and was always a bandaid, with the other fixes in this delta the bandaid can finally be removed. - In the other/link interrupt handler the entire state of the EICS register was being writen back into EICR (which clears causes and thus re-enables those interrupts), this was wrong, so now mask off the queue portion of the register value, so we only clear the other/link interrupt we intend. Marc from Verisign found this. - Make the SFP+ unsupported option tuneable now, by customer request. - Finally, just a couple of minor DEBUG string fixes. I want to call out and thank all the participants in the 10G community/Intel calls for helping track down these problems and make the driver better for everyone! MFC after: 3 days, these are critical fixes for 9.2!

Patch #6 Whitespace cleanup, and removal of some very old defines (at Gleb's request). Also, change the defines around the old transmit code to IXGBE_LEGACY_TX, I do this to make it possible to define this regardless of the OS level (it is not defined by default).

#ifdef IXGBE_LEGACY_TX
This delta fixes two bugs: - When a vlan event occurs a check was not made that the event was actually for the interface, thus resulting in a panic. All three drivers have this vulnerability. Add a check for this condition. - Secondly, there was a duplicate buf_ring free in the em driver resulting in a panic on unload. Remove. Approved by: re

Thanks to Michael Tuexen for adding SCTP support for 82599, also for finding a one character bug that kept TSO from working. Sometimes with direct attach cables a failure can occur in init, the old method of calling detach was broken, there is no way to return an error to the system from init, so I have changed it to return failure thru the ioctl. And, have fixed the ALTQ code changes of Max Laier, sorry Max :)

Update driver to Intel version 2.0.7: This adds new feature support for the 82599, a hardware assist to LRO, doing this required a large revamp to the RX cleanup code because the descriptor ring may not be processed out of order, this necessitated the elimination of global pointers. Additionally, the RX routine now does not refresh mbufs on every descriptor, rather it will do a range, and then update the hardware pointer at that time. These are performance oriented changes. The TX side now has a cleaner simpler watchdog algorithm as well, in TX cleanup a read of ticks is stored, that can then be compared in local_timer to determine if there is a hang. Various other cleanups along the way, thanks to all who have provided input and testing.

Update driver to Intel version 2.0.7: This adds new feature support for the 82599, a hardware assist to LRO, doing this required a large revamp to the RX cleanup code because the descriptor ring may not be processed out of order, this necessitated the elimination of global pointers. Additionally, the RX routine now does not refresh mbufs on every descriptor, rather it will do a range, and then update the hardware pointer at that time. These are performance oriented changes. The TX side now has a cleaner simpler watchdog algorithm as well, in TX cleanup a read of ticks is stored, that can then be compared in local_timer to determine if there is a hang. Various other cleanups along the way, thanks to all who have provided input and testing.

Update the driver to Intel version 2.1.6 - add some new hardware support for 82599 - Big change to interrupt architecture, it now uses a queue which contains an RX/TX pair as the recipient of the interrupt. This will reduce overall system interrupts/msix usage. - Improved RX mbuf handling: the old get_buf routine is no longer synchronized with rxeof, this allows the elimination of packet discards due to mbuf allocation failure. - Much simplified and improved AIM code, it now happens in the queue interrupt context and takes into account both the traffic on the RX AND TX side. - variety of small tweaks, like ring size, that have been seen as performance improvements. - Thanks to those that provided feedback or suggested changes, I hope I've caught all of them.

This also has the benefit of detecting changes when a different module is inserted. Performance/enhancement to the Flow Director code from my linux coworker (the developer of the code). Fixes from Michael Tuexen - a data corruption problem on the 82599 (CRITICAL), fix so the buf size correctly adjusts as the cluster changes, and max descriptors are set properly. Also added 16K clusters for those REALLY big jumbos :) In the RX path, the RX LOCK was not being released, and this causes LOR problems. Add the code that igb already has.

This also has the benefit of detecting changes when a different module is inserted. Performance/enhancement to the Flow Director code from my linux coworker (the developer of the code). Fixes from Michael Tuexen - a data corruption problem on the 82599 (CRITICAL), fix so the buf size correctly adjusts as the cluster changes, and max descriptors are set properly. Also added 16K clusters for those REALLY big jumbos :) In the RX path, the RX LOCK was not being released, and this causes LOR problems. Add the code that igb already has.

Update driver to Intel version 2.0.7: This adds new feature support for the 82599, a hardware assist to LRO, doing this required a large revamp to the RX cleanup code because the descriptor ring may not be processed out of order, this necessitated the elimination of global pointers. Additionally, the RX routine now does not refresh mbufs on every descriptor, rather it will do a range, and then update the hardware pointer at that time. These are performance oriented changes. The TX side now has a cleaner simpler watchdog algorithm as well, in TX cleanup a read of ticks is stored, that can then be compared in local_timer to determine if there is a hang. Various other cleanups along the way, thanks to all who have provided input and testing.

Update the driver to Intel version 2.1.6 - add some new hardware support for 82599 - Big change to interrupt architecture, it now uses a queue which contains an RX/TX pair as the recipient of the interrupt. This will reduce overall system interrupts/msix usage. - Improved RX mbuf handling: the old get_buf routine is no longer synchronized with rxeof, this allows the elimination of packet discards due to mbuf allocation failure. - Much simplified and improved AIM code, it now happens in the queue interrupt context and takes into account both the traffic on the RX AND TX side. - variety of small tweaks, like ring size, that have been seen as performance improvements. - Thanks to those that provided feedback or suggested changes, I hope I've caught all of them.

1. Fix the handling of link reset while in netmap more. A link reset now is completely transparent for the netmap client: even if the NIC resets its own ring (e.g. restarting from 0), the client will not see any change in the current rx/tx positions, because the driver will keep track of the offset between the two. 2. make the device-specific code more uniform across different drivers There were some inconsistencies in the implementation of the netmap support routines, now drivers have been aligned to a common code structure. 3. import netmap support for ixgbe . This is implemented as a very small patch for ixgbe.c (233 lines, 11 chunks, mostly comments: in total the patch has only 54 lines of new code) , as most of the code is in an external file sys/dev/netmap/ixgbe_netmap.h , following some initial comments from Jack Vogel about making changes less intrusive. (Note, i have emailed Jack multiple times asking if he had comments on this structure of the code; i got no reply so i assume he is fine with it). Support for other drivers (em, lem, re, igb) will come later. "ixgbe" is now the reference driver for netmap support. Both the external file (sys/dev/netmap/ixgbe_netmap.h) and the device-specific patches (in sys/dev/ixgbe/ixgbe.c) are heavily commented and should serve as a reference for other device drivers. Tested on i386 and amd64 with the pkt-gen program in tools/tools/netmap, the sender does 14.88 Mpps at 1050 Mhz and 14.2 Mpps at 900 MHz on an i7-860 with 4 cores and 82599 card. Haven't tried yet more aggressive optimizations such as adding 'prefetch' instructions in the time-critical parts of the code.

ixgbe changes: - remove experimental code for disabling CRC - use the correct constant for conversion between interrupt rate and EITR values (the previous values were off by a factor of 2) - make dev.ix.N.queueM.interrupt_rate a RW sysctl variable. Changing individual values affects the queue immediately, and propagates to all interfaces at the next reinit. - add dev.ix.N.queueM.irqs rdonly sysctl, to export the actual interrupt counts Netmap-related changes for ixgbe: - use the "new" format for TX descriptors in netmap mode. - pass interrupt mitigation delays to the user process doing poll() on a netmap file descriptor. On the RX side this means we will not check the ring more than once per interrupt. This gives the process a chance to sleep and process packets in larger batches, thus reducing CPU usage. On the TX side we take this even further: completed transmissions are reclaimed every half ring even if the NIC interrupts more often. This saves even more CPU without any additional tx delays. Generic Netmap-related changes: - align the netmap_kring to cache lines so that there is no false sharing (possibly useful for multiqueue NICs and MSIX interrupts, which are handled by different cores).

Add quad port probe support, this gives the admin proper information about the slot (which should be a PCIE Gen 3 slot for this adapter) by looking back thru the PCI parent devices to the slot device. The fix above also corrects the bandwidth display to GT/s rather than the incorrect Gb/s Next, allow the use of ALTQ if you select the compile option IXGBE_LEGACY_TX. Allow the use of 'unsupported' optic modules by a compile option as well. Add a phy reset capability into the stop code, this is so a static configured driver will still behave properly when taken down (not being able to unload it). This revision synchronizes the shared code with Intel internal current code, and note that it now includes DCB supporting code, this was necessitated by some internal changes with the code, but it also will provide the opportunity to develop this feature in the core driver down the road. I have edited the README to get rid of some of the worse anachronisms in it as well, its by no means as robust as I might wish at this point however. Oh, I also have included some conditional stuff in the code so it will be compatible in both the 9.X and 10 environments. Performance has been a focus in recent changes and I believe this revision driver will perform very well in most workloads. MFC after: 2 weeks

Additionally, the RX routine now does not refresh mbufs on every descriptor, rather it will do a range, and then update the hardware pointer at that time. These are performance oriented changes. The TX side now has a cleaner simpler watchdog algorithm as well, in TX cleanup a read of ticks is stored, that can then be compared in local_timer to determine if there is a hang.

Heavily optimize the case of small RX packets of 160 bytes or less. For this case, allocate a plain mbuf and copy the frame into it, then send the copy up the stack, leaving the original mbuf+cluster in place in the receive ring for immediate re-use. This saves a trip through 2 of the 3 zones of the compound mbuf allocator, a trip through busdma, and a trip through the 1 of the 3 mbuf destructors. For our load at Netflix, this can lower CPU consumption by as much as 20%. The copy algorithm is based on investigative work from Luigi Rizzo earlier in the year.

Update driver to Intel version 2.0.7: This adds new feature support for the 82599, a hardware assist to LRO, doing this required a large revamp to the RX cleanup code because the descriptor ring may not be processed out of order, this necessitated the elimination of global pointers. Additionally, the RX routine now does not refresh mbufs on every descriptor, rather it will do a range, and then update the hardware pointer at that time. These are performance oriented changes. The TX side now has a cleaner simpler watchdog algorithm as well, in TX cleanup a read of ticks is stored, that can then be compared in local_timer to determine if there is a hang. Various other cleanups along the way, thanks to all who have provided input and testing.

Updated ixgbe driver - version 1.6.2 -This version has header split, and as a result a number of aspects of the code have been improved/simplified. - Interrupt handling refined for performance - Many small bugs fixed along the way MFC after: ASAP - in time for 7.1
2008-11-26 23:41:18 +00:00
- Add the RX refresh changes from igb to ixgbe - Also a couple minor tweaks to the TX code from the same source. - Add the INET ioctl code which has been missing from this driver, and which caused IP aliases to reset the interface. - Last, some minor logic changes that just reflect upcoming hardware support, but have no other functional effect now.

Update driver to version 2.3.8: CRITICAL FIX - with stats changes the older 82598 will panic and trash the stack on driver load, FCOE registers ONLY exist in 82599 and must not be read otherwise. kern/153951 - to correct incorrect media type on adapters with pluggable modules I have eliminated the old static table in favor of a new dynamic shared code routine. This also has the benefit of detecting changes when a different module is inserted. Performance/enhancement to the Flow Director code from my linux coworker (the developer of the code). Fixes from Michael Tuexen - a data corruption problem on the 82599 (CRITICAL), fix so the buf size correctly adjusts as the cluster changes, and max descriptors are set properly. Also added 16K clusters for those REALLY big jumbos :) In the RX path, the RX LOCK was not being released, and this causes LOR problems. Add the code that igb already has.

* Initialize Hardware RSC (LRO) feature on 82599

A few important fixes: - Testing TSO6 has led me to discover that HW RSC is a problematic feature, it is ONLY designed to work with IPv4 in the first place, and if IP forwarding is done it can't be disabled as LRO in the stack, also initial testing we've done at Intel shows an equal performance using TSO[46] on the TX and LRO on RX, if you ran older code on 82599 or later hardware you actually could have detrimental performance for this reason. So I am disabling the feature by default and all our adapters will now use LRO instead. - If you have flow control off and multiple queues it was possible when the buffer of one queue becomes full that all RX movement is stalled, to eliminate this problem a feature bit is now set that will allow packets to be dropped when full rather than stall. Note, the default is to have flow control on, and this keeps this from happening. - Because of the recent fixes in the stack, LRO is now auto-disabled when problematic, so I have decided to enable it by default in the capabilities in the driver. - There are some 1G modules used by some customers, a couple small tweaks to properly support those in the media code. - A note: we have now done some testing of TSO6 and using LRO with IPv6 and it all works great!! Seeing line rate in both directions in best cases. Thanks bz for your excellent work!!

This also has the benefit of detecting changes when a different module is inserted. Performance/enhancement to the Flow Director code from my linux coworker (the developer of the code). Fixes from Michael Tuexen - a data corruption problem on the 82599 (CRITICAL), fix so the buf size correctly adjusts as the cluster changes, and max descriptors are set properly. Also added 16K clusters for those REALLY big jumbos :) In the RX path, the RX LOCK was not being released, and this causes LOR problems. Add the code that igb already has. Sync with in house shared code, this was necessary for the Flow Director fix. MFC in 2 days

Update the driver to Intel version 2.1.6 - add some new hardware support for 82599 - Big change to interrupt architecture, it now uses a queue which contains an RX/TX pair as the recipient of the interrupt. This will reduce overall system interrupts/msix usage. - Improved RX mbuf handling: the old get_buf routine is no longer synchronized with rxeof, this allows the elimination of packet discards due to mbuf allocation failure. - Much simplified and improved AIM code, it now happens in the queue interrupt context and takes into account both the traffic on the RX AND TX side. - variety of small tweaks, like ring size, that have been seen as performance improvements. - Thanks to those that provided feedback or suggested changes, I hope I've caught all of them.

A bunch of netmap fixes: USERSPACE: 1. add support for devices with different number of rx and tx queues; 2. add better support for zero-copy operation, adding an extra field to the netmap ring to indicate how many buffers we have already processed but not yet released (with help from Eddie Kohler); 3. The two changes above unfortunately require an API change, so while at it add a version field and some spares to the ioctl() argument to help detect mismatches. 4. update the manual page for the two changes above; 5. update sample applications in tools/tools/netmap KERNEL: 1. simplify the internal structures moving the global wait queues to the 'struct netmap_adapter'; 2. simplify the functions that map kring<->nic ring indexes 3. normalize device-specific code, helps mainteinance; 4. start exploring the impact of micro-optimizations (prefetch etc.) in the ixgbe driver. Use 'legacy' descriptors on the tx ring and prefetch slots gives about 20% speedup at 900 MHz. Another 7-10% would come from removing the explict calls to bus_dmamap* in the core (they are effectively NOPs in this case, but it takes expensive load of the per-buffer dma maps to figure out that they are all NULL. Rx performance not investigated. I am postponing the MFC so i can import a few more improvements before merging.

Thanks to Michael and the team at Verisign for finding this problem. - A couple more spots where the rxbuf->flags member should be cleared just to be sure no incorrect RX_COPY state is left around. Thanks to Adrian for tracking these down. - Remove the rearm_queues function from the driver, this was found to be responsible for some out-of-order packets by Verisign, and was always a bandaid, with the other fixes in this delta the bandaid can finally be removed. - In the other/link interrupt handler the entire state of the EICS register was being writen back into EICR (which clears causes and thus re-enables those interrupts), this was wrong, so now mask off the queue portion of the register value, so we only clear the other/link interrupt we intend. Marc from Verisign found this. - Make the SFP+ unsupported option tuneable now, by customer request. - Finally, just a couple of minor DEBUG string fixes. I want to call out and thank all the participants in the 10G community/Intel calls for helping track down these problems and make the driver better for everyone!

Haven't tried yet more aggressive optimizations such as adding 'prefetch' instructions in the time-critical parts of the code.

A number of important fixes: - mbuf reused after an RX_COPY optimized operation can sometimes have a bogus cached address, resulting in TCP hangs. Add critical save points to the cached address. Thanks to Michael and the team at Verisign for finding this problem. - A couple more spots where the rxbuf->flags member should be cleared just to be sure no incorrect RX_COPY state is left around. Thanks to Adrian for tracking these down. - Remove the rearm_queues function from the driver, this was found to be responsible for some out-of-order packets by Verisign, and was always a bandaid, with the other fixes in this delta the bandaid can finally be removed. - In the other/link interrupt handler the entire state of the EICS register was being writen back into EICR (which clears causes and thus re-enables those interrupts), this was wrong, so now mask off the queue portion of the register value, so we only clear the other/link interrupt we intend.

Update driver to Intel version 2.0.7: This adds new feature support for the 82599, a hardware assist to LRO, doing this required a large revamp to the RX cleanup code because the descriptor ring may not be processed out of order, this necessitated the elimination of global pointers. Additionally, the RX routine now does not refresh mbufs on every descriptor, rather it will do a range, and then update the hardware pointer at that time. These are performance oriented changes. The TX side now has a cleaner simpler watchdog algorithm as well, in TX cleanup a read of ticks is stored, that can then be compared in local_timer to determine if there is a hang.

rxr->lro_enabled = FALSE;
Heavily optimize the case of small RX packets of 160 bytes or less. For this case, allocate a plain mbuf and copy the frame into it, then send the copy up the stack, leaving the original mbuf+cluster in place in the receive ring for immediate re-use. This saves a trip through 2 of the 3 zones of the compound mbuf allocator, a trip through busdma, and a trip through the 1 of the 3 mbuf destructors. For our load at Netflix, this can lower CPU consumption by as much as 20%. The copy algorithm is based on investigative work from Luigi Rizzo earlier in the year.

A few important fixes: - Testing TSO6 has led me to discover that HW RSC is a problematic feature, it is ONLY designed to work with IPv4 in the first place, and if IP forwarding is done it can't be disabled as LRO in the stack, also initial testing we've done at Intel shows an equal performance using TSO[46] on the TX and LRO on RX, if you ran older code on 82599 or later hardware you actually could have detrimental performance for this reason. So I am disabling the feature by default and all our adapters will now use LRO instead. - If you have flow control off and multiple queues it was possible when the buffer of one queue becomes full that all RX movement is stalled, to eliminate this problem a feature bit is now set that will allow packets to be dropped when full rather than stall. Note, the default is to have flow control on, and this keeps this from happening. - Because of the recent fixes in the stack, LRO is now auto-disabled when problematic, so I have decided to enable it by default in the capabilities in the driver. - There are some 1G modules used by some customers, a couple small tweaks to properly support those in the media code. - A note: we have now done some testing of TSO6 and using LRO with IPv6 and it all works great!! Seeing line rate in both directions in best cases. Thanks bz for your excellent work!!

#define IXGBE_SRRCTL_BSIZEHDRSIZE_SHIFT 2
The maximum read size of incoming packets is done in 1024-byte increments. The current code was rounding down the maximum frame size instead of routing up, resulting in a read size of 1024 bytes, in the non-jumbo frame case, and splitting the packets across multiple mbufs. Consequently the above problem exposed another issue, which is when packets were splitted across multiple mbufs, and all of the mbufs in the chain have the M_PKTHDR flag set.

Update driver to version 2.3.8: CRITICAL FIX - with stats changes the older 82598 will panic and trash the stack on driver load, FCOE registers ONLY exist in 82599 and must not be read otherwise. kern/153951 - to correct incorrect media type on adapters with pluggable modules I have eliminated the old static table in favor of a new dynamic shared code routine. This also has the benefit of detecting changes when a different module is inserted. Performance/enhancement to the Flow Director code from my linux coworker (the developer of the code). Fixes from Michael Tuexen - a data corruption problem on the 82599 (CRITICAL), fix so the buf size correctly adjusts as the cluster changes, and max descriptors are set properly. Also added 16K clusters for those REALLY big jumbos :) In the RX path, the RX LOCK was not being released, and this causes LOR problems. Add the code that igb already has. Sync with in house shared code, this was necessary for the Flow Director fix. MFC in 2 days

Update the driver to Intel version 2.1.6 - add some new hardware support for 82599 - Big change to interrupt architecture, it now uses a queue which contains an RX/TX pair as the recipient of the interrupt. This will reduce overall system interrupts/msix usage. - Improved RX mbuf handling: the old get_buf routine is no longer synchronized with rxeof, this allows the elimination of packet discards due to mbuf allocation failure. - Much simplified and improved AIM code, it now happens in the queue interrupt context and takes into account both the traffic on the RX AND TX side. - variety of small tweaks, like ring size, that have been seen as performance improvements. - Thanks to those that provided feedback or suggested changes, I hope I've caught all of them.

Update the driver to Intel version 2.1.6 - add some new hardware support for 82599 - Big change to interrupt architecture, it now uses a queue which contains an RX/TX pair as the recipient of the interrupt. This will reduce overall system interrupts/msix usage. - Improved RX mbuf handling: the old get_buf routine is no longer synchronized with rxeof, this allows the elimination of packet discards due to mbuf allocation failure. - Much simplified and improved AIM code, it now happens in the queue interrupt context and takes into account both the traffic on the RX AND TX side. - variety of small tweaks, like ring size, that have been seen as performance improvements. - Thanks to those that provided feedback or suggested changes, I hope I've caught all of them.

Update driver to version 2.3.8: CRITICAL FIX - with stats changes the older 82598 will panic and trash the stack on driver load, FCOE registers ONLY exist in 82599 and must not be read otherwise. kern/153951 - to correct incorrect media type on adapters with pluggable modules I have eliminated the old static table in favor of a new dynamic shared code routine. This also has the benefit of detecting changes when a different module is inserted. Performance/enhancement to the Flow Director code from my linux coworker (the developer of the code). Fixes from Michael Tuexen - a data corruption problem on the 82599 (CRITICAL), fix so the buf size correctly adjusts as the cluster changes, and max descriptors are set properly. Also added 16K clusters for those REALLY big jumbos :) In the RX path, the RX LOCK was not being released, and this causes LOR problems. Add the code that igb already has.

A number of important fixes: - mbuf reused after an RX_COPY optimized operation can sometimes have a bogus cached address, resulting in TCP hangs. Add critical save points to the cached address. Thanks to Michael and the team at Verisign for finding this problem. - A couple more spots where the rxbuf->flags member should be cleared just to be sure no incorrect RX_COPY state is left around. Thanks to Adrian for tracking these down. - Remove the rearm_queues function from the driver, this was found to be responsible for some out-of-order packets by Verisign, and was always a bandaid, with the other fixes in this delta the bandaid can finally be removed. - In the other/link interrupt handler the entire state of the EICS register was being writen back into EICR (which clears causes and thus re-enables those interrupts), this was wrong, so now mask off the queue portion of the register value, so we only clear the other/link interrupt we intend. Marc from Verisign found this. - Make the SFP+ unsupported option tuneable now, by customer request. - Finally, just a couple of minor DEBUG string fixes. I want to call out and thank all the participants in the 10G community/Intel calls for helping track down these problems and make the driver better for everyone!

1. Fix the handling of link reset while in netmap more. A link reset now is completely transparent for the netmap client: even if the NIC resets its own ring (e.g. restarting from 0), the client will not see any change in the current rx/tx positions, because the driver will keep track of the offset between the two. 2. make the device-specific code more uniform across different drivers There were some inconsistencies in the implementation of the netmap support routines, now drivers have been aligned to a common code structure. 3. import netmap support for ixgbe . This is implemented as a very small patch for ixgbe.c (233 lines, 11 chunks, mostly comments: in total the patch has only 54 lines of new code) , as most of the code is in an external file sys/dev/netmap/ixgbe_netmap.h , following some initial comments from Jack Vogel about making changes less intrusive. (Note, i have emailed Jack multiple times asking if he had comments on this structure of the code; i got no reply so i assume he is fine with it). Support for other drivers (em, lem, re, igb) will come later. "ixgbe" is now the reference driver for netmap support. Both the external file (sys/dev/netmap/ixgbe_netmap.h) and the device-specific patches (in sys/dev/ixgbe/ixgbe.c) are heavily commented and should serve as a reference for other device drivers. Tested on i386 and amd64 with the pkt-gen program in tools/tools/netmap, the sender does 14.88 Mpps at 1050 Mhz and 14.2 Mpps at 900 MHz on an i7-860 with 4 cores and 82599 card. Haven't tried yet more aggressive optimizations such as adding 'prefetch' instructions in the time-critical parts of the code.

use netmap_rx_irq() / netmap_tx_irq() to handle interrupts in netmap mode, removing the logic from individual drivers. (note: if_lem.c not updated yet due to some other pending modifications)

1. Fix the handling of link reset while in netmap more. A link reset now is completely transparent for the netmap client: even if the NIC resets its own ring (e.g. restarting from 0), the client will not see any change in the current rx/tx positions, because the driver will keep track of the offset between the two. 2. make the device-specific code more uniform across different drivers There were some inconsistencies in the implementation of the netmap support routines, now drivers have been aligned to a common code structure. 3. import netmap support for ixgbe . This is implemented as a very small patch for ixgbe.c (233 lines, 11 chunks, mostly comments: in total the patch has only 54 lines of new code) , as most of the code is in an external file sys/dev/netmap/ixgbe_netmap.h , following some initial comments from Jack Vogel about making changes less intrusive. (Note, i have emailed Jack multiple times asking if he had comments on this structure of the code; i got no reply so i assume he is fine with it). Support for other drivers (em, lem, re, igb) will come later. "ixgbe" is now the reference driver for netmap support.

Add quad port probe support, this gives the admin proper information about the slot (which should be a PCIE Gen 3 slot for this adapter) by looking back thru the PCI parent devices to the slot device. The fix above also corrects the bandwidth display to GT/s rather than the incorrect Gb/s Next, allow the use of ALTQ if you select the compile option IXGBE_LEGACY_TX. Allow the use of 'unsupported' optic modules by a compile option as well. Add a phy reset capability into the stop code, this is so a static configured driver will still behave properly when taken down (not being able to unload it). This revision synchronizes the shared code with Intel internal current code, and note that it now includes DCB supporting code, this was necessitated by some internal changes with the code, but it also will provide the opportunity to develop this feature in the core driver down the road. I have edited the README to get rid of some of the worse anachronisms in it as well, its by no means as robust as I might wish at this point however. Oh, I also have included some conditional stuff in the code so it will be compatible in both the 9.X and 10 environments. Performance has been a focus in recent changes and I believe this revision driver will perform very well in most workloads. MFC after: 2 weeks

Update the driver to Intel version 2.1.6 - add some new hardware support for 82599 - Big change to interrupt architecture, it now uses a queue which contains an RX/TX pair as the recipient of the interrupt. This will reduce overall system interrupts/msix usage. - Improved RX mbuf handling: the old get_buf routine is no longer synchronized with rxeof, this allows the elimination of packet discards due to mbuf allocation failure. - Much simplified and improved AIM code, it now happens in the queue interrupt context and takes into account both the traffic on the RX AND TX side. - variety of small tweaks, like ring size, that have been seen as performance improvements. - Thanks to those that provided feedback or suggested changes, I hope I've caught all of them.

Update driver to Intel version 2.0.7: This adds new feature support for the 82599, a hardware assist to LRO, doing this required a large revamp to the RX cleanup code because the descriptor ring may not be processed out of order, this necessitated the elimination of global pointers. Additionally, the RX routine now does not refresh mbufs on every descriptor, rather it will do a range, and then update the hardware pointer at that time. These are performance oriented changes. The TX side now has a cleaner simpler watchdog algorithm as well, in TX cleanup a read of ticks is stored, that can then be compared in local_timer to determine if there is a hang. Various other cleanups along the way, thanks to all who have provided input and testing.

Update the driver to Intel version 2.1.6 - add some new hardware support for 82599 - Big change to interrupt architecture, it now uses a queue which contains an RX/TX pair as the recipient of the interrupt. This will reduce overall system interrupts/msix usage. - Improved RX mbuf handling: the old get_buf routine is no longer synchronized with rxeof, this allows the elimination of packet discards due to mbuf allocation failure. - Much simplified and improved AIM code, it now happens in the queue interrupt context and takes into account both the traffic on the RX AND TX side. - variety of small tweaks, like ring size, that have been seen as performance improvements. - Thanks to those that provided feedback or suggested changes, I hope I've caught all of them.

Thanks to Michael Tuexen for adding SCTP support for 82599, also for finding a one character bug that kept TSO from working. Sometimes with direct attach cables a failure can occur in init, the old method of calling detach was broken, there is no way to return an error to the system from init, so I have changed it to return failure thru the ioctl. And, have fixed the ALTQ code changes of Max Laier, sorry Max :)

/* Now send to the stack or do LRO */
Update driver to version 2.3.8: CRITICAL FIX - with stats changes the older 82598 will panic and trash the stack on driver load, FCOE registers ONLY exist in 82599 and must not be read otherwise. kern/153951 - to correct incorrect media type on adapters with pluggable modules I have eliminated the old static table in favor of a new dynamic shared code routine. This also has the benefit of detecting changes when a different module is inserted. Performance/enhancement to the Flow Director code from my linux coworker (the developer of the code). Fixes from Michael Tuexen - a data corruption problem on the 82599 (CRITICAL), fix so the buf size correctly adjusts as the cluster changes, and max descriptors are set properly. Also added 16K clusters for those REALLY big jumbos :) In the RX path, the RX LOCK was not being released, and this causes LOR problems. Add the code that igb already has. Sync with in house shared code, this was necessary for the Flow Director fix. MFC in 2 days

I have edited the README to get rid of some of the worse anachronisms in it as well, its by no means as robust as I might wish at this point however. Oh, I also have included some conditional stuff in the code so it will be compatible in both the 9.X and 10 environments. Performance has been a focus in recent changes and I believe this revision driver will perform very well in most workloads. MFC after: 2 weeks

Update the driver to Intel version 2.1.6 - add some new hardware support for 82599 - Big change to interrupt architecture, it now uses a queue which contains an RX/TX pair as the recipient of the interrupt. This will reduce overall system interrupts/msix usage. - Improved RX mbuf handling: the old get_buf routine is no longer synchronized with rxeof, this allows the elimination of packet discards due to mbuf allocation failure. - Much simplified and improved AIM code, it now happens in the queue interrupt context and takes into account both the traffic on the RX AND TX side. - variety of small tweaks, like ring size, that have been seen as performance improvements. - Thanks to those that provided feedback or suggested changes, I hope I've caught all of them.

Thanks to Michael Tuexen for adding SCTP support for 82599, also for finding a one character bug that kept TSO from working. Sometimes with direct attach cables a failure can occur in init, the old method of calling detach was broken, there is no way to return an error to the system from init, so I have changed it to return failure thru the ioctl. And, have fixed the ALTQ code changes of Max Laier, sorry Max :)

Restructure the mbuf pkthdr to make it fit for upcoming capabilities and features. The changes in particular are: o Remove rarely used "header" pointer and replace it with a 64bit protocol/ layer specific union PH_loc for local use. Protocols can flexibly overlay their own 8 to 64 bit fields to store information while the packet is worked on. o Mechanically convert IP reassembly, IGMP/MLD and ATM to use pkthdr.PH_loc instead of pkthdr.header. o Extend csum_flags to 64bits to allow for additional future offload information to be carried (e.g. iSCSI, IPsec offload, and others). o Move the RSS hash type enumerator from abusing m_flags to its own 8bit rsstype field. Adjust accessor macros. o Add cosqos field to store Class of Service / Quality of Service information with the packet. It is not yet supported in any drivers but allows us to get on par with Cisco/Juniper in routing applications (plus MPLS QoS) with a modernized ALTQ. o Add four 8 bit fields l[2-5]hlen to store the relative header offsets from the start of the packet. This is important for various offload capabilities and to relieve the drivers from having to parse the packet and protocol headers to find out location of checksums and other information. Header parsing in drivers is a lot of copy-paste and unhandled corner cases which we want to avoid. o Add another flexible 64bit union to map various additional persistent packet information, like ether_vtag, tso_segsz and csum fields. Depending on the csum_flags settings some fields may have different usage making it very flexible and adaptable to future capabilities. o Restructure the CSUM flags to better signify their outbound (down the stack) and inbound (up the stack) use. The CSUM flags used to be a bit chaotic and rather poorly documented leading to incorrect use in many places. Bring clarity into their use through better naming. Compatibility mappings are provided to preserve the API. The drivers can be corrected one by one and MFC'd without issue. o The size of pkthdr stays the same at 48/56bytes (32/64bit architectures).

Update driver to Intel version 2.0.7: This adds new feature support for the 82599, a hardware assist to LRO, doing this required a large revamp to the RX cleanup code because the descriptor ring may not be processed out of order, this necessitated the elimination of global pointers. Additionally, the RX routine now does not refresh mbufs on every descriptor, rather it will do a range, and then update the hardware pointer at that time. These are performance oriented changes. The TX side now has a cleaner simpler watchdog algorithm as well, in TX cleanup a read of ticks is stored, that can then be compared in local_timer to determine if there is a hang. Various other cleanups along the way, thanks to all who have provided input and testing.

Add quad port probe support, this gives the admin proper information about the slot (which should be a PCIE Gen 3 slot for this adapter) by looking back thru the PCI parent devices to the slot device. The fix above also corrects the bandwidth display to GT/s rather than the incorrect Gb/s Next, allow the use of ALTQ if you select the compile option IXGBE_LEGACY_TX. Allow the use of 'unsupported' optic modules by a compile option as well. Add a phy reset capability into the stop code, this is so a static configured driver will still behave properly when taken down (not being able to unload it). This revision synchronizes the shared code with Intel internal current code, and note that it now includes DCB supporting code, this was necessitated by some internal changes with the code, but it also will provide the opportunity to develop this feature in the core driver down the road. I have edited the README to get rid of some of the worse anachronisms in it as well, its by no means as robust as I might wish at this point however. Oh, I also have included some conditional stuff in the code so it will be compatible in both the 9.X and 10 environments. Performance has been a focus in recent changes and I believe this revision driver will perform very well in most workloads. MFC after: 2 weeks

ixgbe changes: - remove experimental code for disabling CRC - use the correct constant for conversion between interrupt rate and EITR values (the previous values were off by a factor of 2) - make dev.ix.N.queueM.interrupt_rate a RW sysctl variable. Changing individual values affects the queue immediately, and propagates to all interfaces at the next reinit. - add dev.ix.N.queueM.irqs rdonly sysctl, to export the actual interrupt counts Netmap-related changes for ixgbe: - use the "new" format for TX descriptors in netmap mode. - pass interrupt mitigation delays to the user process doing poll() on a netmap file descriptor. On the RX side this means we will not check the ring more than once per interrupt. This gives the process a chance to sleep and process packets in larger batches, thus reducing CPU usage. On the TX side we take this even further: completed transmissions are reclaimed every half ring even if the NIC interrupts more often. This saves even more CPU without any additional tx delays. Generic Netmap-related changes: - align the netmap_kring to cache lines so that there is no false sharing (possibly useful for multiqueue NICs and MSIX interrupts, which are handled by different cores). It's a minor improvement but it does not cost anything. Reviewed by: Jack Vogel Approved by: Jack Vogel

IXGBE_EITR(que->msix), newitr);
Update the driver to Intel version 2.1.6 - add some new hardware support for 82599 - Big change to interrupt architecture, it now uses a queue which contains an RX/TX pair as the recipient of the interrupt. This will reduce overall system interrupts/msix usage. - Improved RX mbuf handling: the old get_buf routine is no longer synchronized with rxeof, this allows the elimination of packet discards due to mbuf allocation failure. - Much simplified and improved AIM code, it now happens in the queue interrupt context and takes into account both the traffic on the RX AND TX side. - variety of small tweaks, like ring size, that have been seen as performance improvements. - Thanks to those that provided feedback or suggested changes, I hope I've caught all of them.

Update driver to version 2.3.8: CRITICAL FIX - with stats changes the older 82598 will panic and trash the stack on driver load, FCOE registers ONLY exist in 82599 and must not be read otherwise. kern/153951 - to correct incorrect media type on adapters with pluggable modules I have eliminated the old static table in favor of a new dynamic shared code routine. This also has the benefit of detecting changes when a different module is inserted. Performance/enhancement to the Flow Director code from my linux coworker (the developer of the code). Fixes from Michael Tuexen - a data corruption problem on the 82599 (CRITICAL), fix so the buf size correctly adjusts as the cluster changes, and max descriptors are set properly. Also added 16K clusters for those REALLY big jumbos :) In the RX path, the RX LOCK was not being released, and this causes LOR problems. Add the code that igb already has. Sync with in house shared code, this was necessary for the Flow Director fix. MFC in 2 days

Update driver to Intel version 2.0.7: This adds new feature support for the 82599, a hardware assist to LRO, doing this required a large revamp to the RX cleanup code because the descriptor ring may not be processed out of order, this necessitated the elimination of global pointers. Additionally, the RX routine now does not refresh mbufs on every descriptor, rather it will do a range, and then update the hardware pointer at that time. These are performance oriented changes. The TX side now has a cleaner simpler watchdog algorithm as well, in TX cleanup a read of ticks is stored, that can then be compared in local_timer to determine if there is a hang.

The drbr(9) API appeared to be so unclear, that most drivers in tree used it incorrectly, which lead to inaccurate overrated if_obytes accounting. The drbr(9) used to update ifnet stats on drbr_enqueue(), which is not accurate since enqueuing doesn't imply successful processing by driver. Dequeuing neither mean that. Most drivers also called drbr_stats_update() which did accounting again, leading to doubled if_obytes statistics. And in case of severe transmitting, when a packet could be several times enqueued and dequeued it could have been accounted several times. o Thus, make drbr(9) API thinner. Now drbr(9) merely chooses between ALTQ queueing or buf_ring(9) queueing. - It doesn't touch the buf_ring stats any more. - It doesn't touch ifnet stats anymore. - drbr_stats_update() no longer exists. o buf_ring(9) handles its stats itself: - It handles br_drops itself. - br_prod_bytes stats are dropped. Rationale: no one ever reads them but update of a common counter on every packet negatively affects performance due to excessive cache invalidation. - buf_ring_enqueue_bytes() reduced to buf_ring_enqueue(), since we no longer account bytes. o Drivers handle their stats theirselves: if_obytes, if_omcasts. o mlx4(4), igb(4), em(4), vxge(4), oce(4) and ixv(4) no longer use drbr_stats_update(), and update ifnet stats theirselves. o bxe(4) was the most correct driver, it didn't call drbr_stats_update(), thus it was the only driver accurate under moderate load. Now it also maintains stats itself. o ixgbe(4) had already taken stats from hardware, so just - drop software stats updating. - take multicast packet count from hardware as well. o mxge(4) just no longer needs NO_SLOW_STATS define. o cxgb(4), cxgbe(4) need no change, since they obtain stats from hardware.

ixgbe changes: - remove experimental code for disabling CRC - use the correct constant for conversion between interrupt rate and EITR values (the previous values were off by a factor of 2) - make dev.ix.N.queueM.interrupt_rate a RW sysctl variable. Changing individual values affects the queue immediately, and propagates to all interfaces at the next reinit. - add dev.ix.N.queueM.irqs rdonly sysctl, to export the actual interrupt counts Netmap-related changes for ixgbe: - use the "new" format for TX descriptors in netmap mode. - pass interrupt mitigation delays to the user process doing poll() on a netmap file descriptor. On the RX side this means we will not check the ring more than once per interrupt. This gives the process a chance to sleep and process packets in larger batches, thus reducing CPU usage. On the TX side we take this even further: completed transmissions are reclaimed every half ring even if the NIC interrupts more often. This saves even more CPU without any additional tx delays. Generic Netmap-related changes: - align the netmap_kring to cache lines so that there is no false sharing (possibly useful for multiqueue NICs and MSIX interrupts, which are handled by different cores). It's a minor improvement but it does not cost anything. Reviewed by: Jack Vogel Approved by: Jack Vogel

ixgbe changes: - remove experimental code for disabling CRC - use the correct constant for conversion between interrupt rate and EITR values (the previous values were off by a factor of 2) - make dev.ix.N.queueM.interrupt_rate a RW sysctl variable. Changing individual values affects the queue immediately, and propagates to all interfaces at the next reinit. - add dev.ix.N.queueM.irqs rdonly sysctl, to export the actual interrupt counts Netmap-related changes for ixgbe: - use the "new" format for TX descriptors in netmap mode. - pass interrupt mitigation delays to the user process doing poll() on a netmap file descriptor. On the RX side this means we will not check the ring more than once per interrupt. This gives the process a chance to sleep and process packets in larger batches, thus reducing CPU usage. On the TX side we take this even further: completed transmissions are reclaimed every half ring even if the NIC interrupts more often. This saves even more CPU without any additional tx delays. Generic Netmap-related changes: - align the netmap_kring to cache lines so that there is no false sharing (possibly useful for multiqueue NICs and MSIX interrupts, which are handled by different cores). It's a minor improvement but it does not cost anything. Reviewed by: Jack Vogel Approved by: Jack Vogel

Heavily optimize the case of small RX packets of 160 bytes or less. For this case, allocate a plain mbuf and copy the frame into it, then send the copy up the stack, leaving the original mbuf+cluster in place in the receive ring for immediate re-use. This saves a trip through 2 of the 3 zones of the compound mbuf allocator, a trip through busdma, and a trip through the 1 of the 3 mbuf destructors. For our load at Netflix, this can lower CPU consumption by as much as 20%. The copy algorithm is based on investigative work from Luigi Rizzo earlier in the year.

Patch #4 - this does two things, it removes a number of statistics, these are FCOE stats (fiber channel over ethernet), something that FreeBSD does not yet have, they were mistaken for flow control by the implementor I believe. Secondly, the real flow control stats are oddly named with a 'link' tag on the front, it was requested by my validation engineer to make these stats have the same name as the igb driver for clarity and that seemed reasonable to me.

A few important fixes: - Testing TSO6 has led me to discover that HW RSC is a problematic feature, it is ONLY designed to work with IPv4 in the first place, and if IP forwarding is done it can't be disabled as LRO in the stack, also initial testing we've done at Intel shows an equal performance using TSO[46] on the TX and LRO on RX, if you ran older code on 82599 or later hardware you actually could have detrimental performance for this reason. So I am disabling the feature by default and all our adapters will now use LRO instead. - If you have flow control off and multiple queues it was possible when the buffer of one queue becomes full that all RX movement is stalled, to eliminate this problem a feature bit is now set that will allow packets to be dropped when full rather than stall. Note, the default is to have flow control on, and this keeps this from happening. - Because of the recent fixes in the stack, LRO is now auto-disabled when problematic, so I have decided to enable it by default in the capabilities in the driver. - There are some 1G modules used by some customers, a couple small tweaks to properly support those in the media code. - A note: we have now done some testing of TSO6 and using LRO with IPv6 and it all works great!! Seeing line rate in both directions in best cases. Thanks bz for your excellent work!!

First off: update the driver README, the old one was horribly crusty, and this still isn't perfect, but its at least a bit more recent. Secondly, a few improvements to the driver from Andrew Boyer, support hint to allow devices to not attach, add VLAN_HWTSO capability so vlans can use TSO, fix in the interrupt handler to make sure the stack TX queue is processed. Oh, and also make sure IPv6 does not cause a re-init in the ioctl routine. Thanks for your efforts Andrew! Thanks to Claudio Jeker for noticing the ixgbe_xmit() routine was not correctly swapping the dma map from the first to the last descriptor in a multi-descriptor transmission, corrected this.

** Thermal Shutdown Trigger
** - cause a Thermal Overtemp IRQ
Add quad port probe support, this gives the admin proper information about the slot (which should be a PCIE Gen 3 slot for this adapter) by looking back thru the PCI parent devices to the slot device. The fix above also corrects the bandwidth display to GT/s rather than the incorrect Gb/s Next, allow the use of ALTQ if you select the compile option IXGBE_LEGACY_TX. Allow the use of 'unsupported' optic modules by a compile option as well. Add a phy reset capability into the stop code, this is so a static configured driver will still behave properly when taken down (not being able to unload it). This revision synchronizes the shared code with Intel internal current code, and note that it now includes DCB supporting code, this was necessitated by some internal changes with the code, but it also will provide the opportunity to develop this feature in the core driver down the road. I have edited the README to get rid of some of the worse anachronisms in it as well, its by no means as robust as I might wish at this point however. Oh, I also have included some conditional stuff in the code so it will be compatible in both the 9.X and 10 environments. Performance has been a focus in recent changes and I believe this revision driver will perform very well in most workloads. MFC after: 2 weeks

Note, the default is to have flow control on, and this keeps this from happening. - Because of the recent fixes in the stack, LRO is now auto-disabled when problematic, so I have decided to enable it by default in the capabilities in the driver. - There are some 1G modules used by some customers, a couple small tweaks to properly support those in the media code. - A note: we have now done some testing of TSO6 and using LRO with IPv6 and it all works great!! Seeing line rate in both directions in best cases. Thanks bz for your excellent work!!
