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.

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

#ifndef IXGBE_STANDALONE_BUILD
- 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.

#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"
Add initial RSS awareness to the ixgbe(4) driver. The ixgbe(4) hardware is capable of RSS hashing RX packets and doing RSS queue selection for up to 8 queues. However, even if multi-queue is enabled for ixgbe(4), the RX path doesn't use the RSS flowid from the received descriptor. It just uses the MSIX queue id. This patch does a handful of things if RSS is enabled: * Instead of using a random key at boot, fetch the RSS key from the RSS code and program that in to the RSS redirection table. That whole chunk of code should be double checked for endian correctness. * Use the RSS queue mapping to CPU ID to figure out where to thread pin the RX swi thread and the taskqueue threads for each queue. * The software queue is now really an "RSS bucket". * When programming the RSS indirection table, use the RSS code to figure out which RSS bucket each slot in the indirection table maps to. * When transmitting, use the flowid RSS mapping if the mbuf has an RSS aware hash. The existing method wasn't guaranteed to align correctly with the destination RSS bucket (and thus CPU ID.) This code warns if the number of RSS buckets isn't the same as the automatically configured number of hardware queues. The administrator will have to tweak one of them for better performance. There's currently no way to re-balance the RSS indirection table after startup. I'll worry about that later. Additionally, it may be worthwhile to always use the full 32 bit flowid if multi-queue is enabled. It'll make things like lagg(4) behave better with respect to traffic distribution.

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.

#ifdef RSS
Fix ixgbe(4) to compile - with RSS; with ix+ixv in the kernel. * Fix the multiple same-named devclasses; the duplicate name trips up the linker. * Re-do the taskqueue stuff to use the new cpuset API, not the old pinned API. * Add includes for the new location of the RSS configuration routines. This allows ixgbe to compile as a module /and/ linked into the kernel, along with RSS working. Sponsored by: Norse Corp, Inc.

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 :)

Update to the Intel ixgbe driver: - Split the driver into independent pf and vf loadables. This is in preparation for SRIOV support which will be following shortly. This also allows us to keep a seperate revision control over the two parts, making for easier sustaining. - Make the TX/RX code a shared/seperated file, in the old code base the ixv code would miss fixes that went into ixgbe, this model will eliminate that problem. - The driver loadables will now match the device names, something that has been requested for some time. - Rather than a modules/ixgbe there is now modules/ix and modules/ixv - It will also be possible to make your static kernel with only one or the other for streamlined installs, or both.

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 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.

Fix ixgbe(4) to compile - with RSS; with ix+ixv in the kernel. * Fix the multiple same-named devclasses; the duplicate name trips up the linker. * Re-do the taskqueue stuff to use the new cpuset API, not the old pinned API. * Add includes for the new location of the RSS configuration routines. This allows ixgbe to compile as a module /and/ linked into the kernel, along with RSS working. Sponsored by: Norse Corp, Inc.

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.

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.

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.

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 to the Intel ixgbe driver: - Split the driver into independent pf and vf loadables. This is in preparation for SRIOV support which will be following shortly. This also allows us to keep a seperate revision control over the two parts, making for easier sustaining. - Make the TX/RX code a shared/seperated file, in the old code base the ixv code would miss fixes that went into ixgbe, this model will eliminate that problem. - The driver loadables will now match the device names, something that has been requested for some time. - Rather than a modules/ixgbe there is now modules/ix and modules/ixv - It will also be possible to make your static kernel with only one or the other for streamlined installs, or both.

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

/* Check PCIE slot type/speed/width */
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 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 to the Intel ixgbe driver: - Split the driver into independent pf and vf loadables. This is in preparation for SRIOV support which will be following shortly. This also allows us to keep a seperate revision control over the two parts, making for easier sustaining. - Make the TX/RX code a shared/seperated file, in the old code base the ixv code would miss fixes that went into ixgbe, this model will eliminate that problem. - The driver loadables will now match the device names, something that has been requested for some time. - Rather than a modules/ixgbe there is now modules/ix and modules/ixv - It will also be possible to make your static kernel with only one or the other for streamlined installs, or both.

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.

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.

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.

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 :)

Update to the Intel ixgbe driver: - Split the driver into independent pf and vf loadables. This is in preparation for SRIOV support which will be following shortly. This also allows us to keep a seperate revision control over the two parts, making for easier sustaining. - Make the TX/RX code a shared/seperated file, in the old code base the ixv code would miss fixes that went into ixgbe, this model will eliminate that problem. - The driver loadables will now match the device names, something that has been requested for some time. - Rather than a modules/ixgbe there is now modules/ix and modules/ixv - It will also be possible to make your static kernel with only one or the other for streamlined installs, or both.

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.

mtx_assert(&adapter->core_mtx, MA_OWNED);
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 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.

/* aka IXGBE_MAXFRS on 82599 and newer */
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.

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.

txdctl |= (8 << 16);
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.)

It is 2014 and we have a new version of netmap. Most relevant features: - netmap emulation on any NIC, even those without native netmap support. On the ixgbe we have measured about 4Mpps/core/queue in this mode, which is still a lot more than with sockets/bpf. - seamless interconnection of VALE switch, NICs and host stack. If you disable accelerations on your NIC (say em0) ifconfig em0 -txcsum -txcsum you can use the VALE switch to connect the NIC and the host stack: vale-ctl -h valeXX:em0 allowing sharing the NIC with other netmap clients. - THE USER API HAS SLIGHTLY CHANGED (head/cur/tail pointers instead of pointers/count as before). This was unavoidable to support, in the future, multiple threads operating on the same rings. Netmap clients require very small source code changes to compile again. On the plus side, the new API should be easier to understand and the internals are a lot simpler. The manual page has been updated extensively to reflect the current features and give some examples. This is the result of work of several people including Giuseppe Lettieri, Vincenzo Maffione, Michio Honda and myself, and has been financially supported by EU projects CHANGE and OPENLAB, from NetApp University Research Fund, NEC, and of course the Universita` di Pisa.

This also allows us to keep a seperate revision control over the two parts, making for easier sustaining. - Make the TX/RX code a shared/seperated file, in the old code base the ixv code would miss fixes that went into ixgbe, this model will eliminate that problem. - The driver loadables will now match the device names, something that has been requested for some time. - Rather than a modules/ixgbe there is now modules/ix and modules/ixv - It will also be possible to make your static kernel with only one or the other for streamlined installs, or both. Enjoy! Submitted by: jfv and erj

Add support for certain Intel X550 devices. These include standalone X550 adapters, X552 10GbE backplane, and X552/X557-AT 10GBASE-T; with the latter two being integrated into Xeon D SoCs. As well, this bumps the ixgbe version number to 2.8.3, and includes updates to shared code for support for the new devices.

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.

Update to the Intel ixgbe driver: - Split the driver into independent pf and vf loadables. This is in preparation for SRIOV support which will be following shortly. This also allows us to keep a seperate revision control over the two parts, making for easier sustaining. - Make the TX/RX code a shared/seperated file, in the old code base the ixv code would miss fixes that went into ixgbe, this model will eliminate that problem. - The driver loadables will now match the device names, something that has been requested for some time. - Rather than a modules/ixgbe there is now modules/ix and modules/ixv - It will also be possible to make your static kernel with only one or the other for streamlined installs, or both.

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!

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.

#ifdef IXGBE_LEGACY_TX
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

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.

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 the ixgbe driver to 1.7.4, this includes support for the new 82599 adapter family, adds header split, and many small fixes. The driver should now be added to the GENERIC kernel. MFC after: 2 weeks

Update to the Intel ixgbe driver: - Split the driver into independent pf and vf loadables. This is in preparation for SRIOV support which will be following shortly. This also allows us to keep a seperate revision control over the two parts, making for easier sustaining. - Make the TX/RX code a shared/seperated file, in the old code base the ixv code would miss fixes that went into ixgbe, this model will eliminate that problem. - The driver loadables will now match the device names, something that has been requested for some time. - Rather than a modules/ixgbe there is now modules/ix and modules/ixv - It will also be possible to make your static kernel with only one or the other for streamlined installs, or both.

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.

Update to the Intel ixgbe driver: - Split the driver into independent pf and vf loadables. This is in preparation for SRIOV support which will be following shortly. This also allows us to keep a seperate revision control over the two parts, making for easier sustaining. - Make the TX/RX code a shared/seperated file, in the old code base the ixv code would miss fixes that went into ixgbe, this model will eliminate that problem. - The driver loadables will now match the device names, something that has been requested for some time. - Rather than a modules/ixgbe there is now modules/ix and modules/ixv - It will also be possible to make your static kernel with only one or the other for streamlined installs, or both.

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 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

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

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.

Add initial RSS awareness to the ixgbe(4) driver. The ixgbe(4) hardware is capable of RSS hashing RX packets and doing RSS queue selection for up to 8 queues. However, even if multi-queue is enabled for ixgbe(4), the RX path doesn't use the RSS flowid from the received descriptor. It just uses the MSIX queue id. This patch does a handful of things if RSS is enabled: * Instead of using a random key at boot, fetch the RSS key from the RSS code and program that in to the RSS redirection table. That whole chunk of code should be double checked for endian correctness. * Use the RSS queue mapping to CPU ID to figure out where to thread pin the RX swi thread and the taskqueue threads for each queue. * The software queue is now really an "RSS bucket". * When programming the RSS indirection table, use the RSS code to figure out which RSS bucket each slot in the indirection table maps to. * When transmitting, use the flowid RSS mapping if the mbuf has an RSS aware hash. The existing method wasn't guaranteed to align correctly with the destination RSS bucket (and thus CPU ID.) This code warns if the number of RSS buckets isn't the same as the automatically configured number of hardware queues. The administrator will have to tweak one of them for better performance. There's currently no way to re-balance the RSS indirection table after startup. I'll worry about that later. Additionally, it may be worthwhile to always use the full 32 bit flowid if multi-queue is enabled. It'll make things like lagg(4) behave better with respect to traffic distribution.

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 initial RSS awareness to the ixgbe(4) driver. The ixgbe(4) hardware is capable of RSS hashing RX packets and doing RSS queue selection for up to 8 queues. However, even if multi-queue is enabled for ixgbe(4), the RX path doesn't use the RSS flowid from the received descriptor. It just uses the MSIX queue id. This patch does a handful of things if RSS is enabled: * Instead of using a random key at boot, fetch the RSS key from the RSS code and program that in to the RSS redirection table. That whole chunk of code should be double checked for endian correctness. * Use the RSS queue mapping to CPU ID to figure out where to thread pin the RX swi thread and the taskqueue threads for each queue. * The software queue is now really an "RSS bucket". * When programming the RSS indirection table, use the RSS code to figure out which RSS bucket each slot in the indirection table maps to. * When transmitting, use the flowid RSS mapping if the mbuf has an RSS aware hash. The existing method wasn't guaranteed to align correctly with the destination RSS bucket (and thus CPU ID.) This code warns if the number of RSS buckets isn't the same as the automatically configured number of hardware queues. The administrator will have to tweak one of them for better performance. There's currently no way to re-balance the RSS indirection table after startup. I'll worry about that later. Additionally, it may be worthwhile to always use the full 32 bit flowid if multi-queue is enabled. It'll make things like lagg(4) behave better with respect to traffic distribution.

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 initial RSS awareness to the ixgbe(4) driver. The ixgbe(4) hardware is capable of RSS hashing RX packets and doing RSS queue selection for up to 8 queues. However, even if multi-queue is enabled for ixgbe(4), the RX path doesn't use the RSS flowid from the received descriptor. It just uses the MSIX queue id. This patch does a handful of things if RSS is enabled: * Instead of using a random key at boot, fetch the RSS key from the RSS code and program that in to the RSS redirection table. That whole chunk of code should be double checked for endian correctness. * Use the RSS queue mapping to CPU ID to figure out where to thread pin the RX swi thread and the taskqueue threads for each queue. * The software queue is now really an "RSS bucket". * When programming the RSS indirection table, use the RSS code to figure out which RSS bucket each slot in the indirection table maps to. * When transmitting, use the flowid RSS mapping if the mbuf has an RSS aware hash. The existing method wasn't guaranteed to align correctly with the destination RSS bucket (and thus CPU ID.) This code warns if the number of RSS buckets isn't the same as the automatically configured number of hardware queues. The administrator will have to tweak one of them for better performance. There's currently no way to re-balance the RSS indirection table after startup. I'll worry about that later. Additionally, it may be worthwhile to always use the full 32 bit flowid if multi-queue is enabled. It'll make things like lagg(4) behave better with respect to traffic distribution.

Update to the Intel ixgbe driver: - Split the driver into independent pf and vf loadables. This is in preparation for SRIOV support which will be following shortly. This also allows us to keep a seperate revision control over the two parts, making for easier sustaining. - Make the TX/RX code a shared/seperated file, in the old code base the ixv code would miss fixes that went into ixgbe, this model will eliminate that problem. - The driver loadables will now match the device names, something that has been requested for some time. - Rather than a modules/ixgbe there is now modules/ix and modules/ixv - It will also be possible to make your static kernel with only one or the other for streamlined installs, or both.

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.

Since 32-bit if_baudrate isn't enough to describe a baud rate of a 10 Gbit interface, in the r241616 a crutch was provided. It didn't work well, and finally we decided that it is time to break ABI and simply make if_baudrate a 64-bit value. Meanwhile, the entire struct if_data was reviewed. o Remove the if_baudrate_pf crutch. o Make all fields of struct if_data fixed machine independent size. The notion of data (packet counters, etc) are by no means MD. And it is a bug that on amd64 we've got a 64-bit counters, while on i386 32-bit, which at modern speeds overflow within a second. This also removes quite a lot of COMPAT_FREEBSD32 code. o Give 16 bit for the ifi_datalen field. This field was provided to make future changes to if_data less ABI breaking. Unfortunately the 8 bit size of it had effectively limited sizeof if_data to 256 bytes. o Give 32 bits to ifi_mtu and ifi_metric. o Give 64 bits to the rest of fields, since they are counters. __FreeBSD_version bumped.

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.

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

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 to the Intel ixgbe driver: - Split the driver into independent pf and vf loadables. This is in preparation for SRIOV support which will be following shortly. This also allows us to keep a seperate revision control over the two parts, making for easier sustaining. - Make the TX/RX code a shared/seperated file, in the old code base the ixv code would miss fixes that went into ixgbe, this model will eliminate that problem. - The driver loadables will now match the device names, something that has been requested for some time. - Rather than a modules/ixgbe there is now modules/ix and modules/ixv - It will also be possible to make your static kernel with only one or the other for streamlined installs, or both.

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.

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.

This also allows us to keep a seperate revision control over the two parts, making for easier sustaining. - Make the TX/RX code a shared/seperated file, in the old code base the ixv code would miss fixes that went into ixgbe, this model will eliminate that problem. - The driver loadables will now match the device names, something that has been requested for some time. - Rather than a modules/ixgbe there is now modules/ix and modules/ixv - It will also be possible to make your static kernel with only one or the other for streamlined installs, or both.

Add initial RSS awareness to the ixgbe(4) driver. The ixgbe(4) hardware is capable of RSS hashing RX packets and doing RSS queue selection for up to 8 queues. However, even if multi-queue is enabled for ixgbe(4), the RX path doesn't use the RSS flowid from the received descriptor. It just uses the MSIX queue id. This patch does a handful of things if RSS is enabled: * Instead of using a random key at boot, fetch the RSS key from the RSS code and program that in to the RSS redirection table. That whole chunk of code should be double checked for endian correctness. * Use the RSS queue mapping to CPU ID to figure out where to thread pin the RX swi thread and the taskqueue threads for each queue. * The software queue is now really an "RSS bucket". * When programming the RSS indirection table, use the RSS code to figure out which RSS bucket each slot in the indirection table maps to. * When transmitting, use the flowid RSS mapping if the mbuf has an RSS aware hash. The existing method wasn't guaranteed to align correctly with the destination RSS bucket (and thus CPU ID.) This code warns if the number of RSS buckets isn't the same as the automatically configured number of hardware queues. The administrator will have to tweak one of them for better performance. There's currently no way to re-balance the RSS indirection table after startup. I'll worry about that later. Additionally, it may be worthwhile to always use the full 32 bit flowid if multi-queue is enabled. It'll make things like lagg(4) behave better with respect to traffic distribution.

However, even if multi-queue is enabled for ixgbe(4), the RX path doesn't use the RSS flowid from the received descriptor. It just uses the MSIX queue id. This patch does a handful of things if RSS is enabled: * Instead of using a random key at boot, fetch the RSS key from the RSS code and program that in to the RSS redirection table. That whole chunk of code should be double checked for endian correctness. * Use the RSS queue mapping to CPU ID to figure out where to thread pin the RX swi thread and the taskqueue threads for each queue. * The software queue is now really an "RSS bucket". * When programming the RSS indirection table, use the RSS code to figure out which RSS bucket each slot in the indirection table maps to. * When transmitting, use the flowid RSS mapping if the mbuf has an RSS aware hash. The existing method wasn't guaranteed to align correctly with the destination RSS bucket (and thus CPU ID.) This code warns if the number of RSS buckets isn't the same as the automatically configured number of hardware queues. The administrator will have to tweak one of them for better performance. There's currently no way to re-balance the RSS indirection table after startup. I'll worry about that later. Additionally, it may be worthwhile to always use the full 32 bit flowid if multi-queue is enabled. It'll make things like lagg(4) behave better with respect to traffic distribution.

Disable the ixgbe(4) UDP 4-tuple hashing for the time being. A mix of fragmented and non-fragmented UDP in a single stream will end up being hashed differently, resulting in out-of-order behaviour in the receive path. This was done in the linux e1000 driver in 2011. Discussed with: jfv

Teach ixgbe(4) about rss_gethashconfig(). If RSS is enabled, ixgbe(4) will query the RSS API for the types of hashes which should be used. It'll then only enable hashes that are exposed via the RSS layer. This way it won't try to do things like enable UDP hashing if RSS explicitly states that it isn't supported in lookups.

#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.

A few changes: When not defining header split do not allocate mbufs, this can be a BIG savings in the mbuf memory pool. Also keep seperate dma maps for the header and payload pieces when doing header split. The basis of this code was a patch done a while ago by yongari, thank you :) A number of white space changes.

Add initial RSS awareness to the ixgbe(4) driver. The ixgbe(4) hardware is capable of RSS hashing RX packets and doing RSS queue selection for up to 8 queues. However, even if multi-queue is enabled for ixgbe(4), the RX path doesn't use the RSS flowid from the received descriptor. It just uses the MSIX queue id. This patch does a handful of things if RSS is enabled: * Instead of using a random key at boot, fetch the RSS key from the RSS code and program that in to the RSS redirection table. That whole chunk of code should be double checked for endian correctness. * Use the RSS queue mapping to CPU ID to figure out where to thread pin the RX swi thread and the taskqueue threads for each queue. * The software queue is now really an "RSS bucket". * When programming the RSS indirection table, use the RSS code to figure out which RSS bucket each slot in the indirection table maps to. * When transmitting, use the flowid RSS mapping if the mbuf has an RSS aware hash. The existing method wasn't guaranteed to align correctly with the destination RSS bucket (and thus CPU ID.) This code warns if the number of RSS buckets isn't the same as the automatically configured number of hardware queues. The administrator will have to tweak one of them for better performance. There's currently no way to re-balance the RSS indirection table after startup. I'll worry about that later. Additionally, it may be worthwhile to always use the full 32 bit flowid if multi-queue is enabled. It'll make things like lagg(4) behave better with respect to traffic distribution.

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.

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

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.

if (ixgbe_max_interrupt_rate > 0)
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 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.

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 support for certain Intel X550 devices. These include standalone X550 adapters, X552 10GbE backplane, and X552/X557-AT 10GBASE-T; with the latter two being integrated into Xeon D SoCs. As well, this bumps the ixgbe version number to 2.8.3, and includes updates to shared code for support for the new devices.

This also allows us to keep a seperate revision control over the two parts, making for easier sustaining. - Make the TX/RX code a shared/seperated file, in the old code base the ixv code would miss fixes that went into ixgbe, this model will eliminate that problem. - The driver loadables will now match the device names, something that has been requested for some time. - Rather than a modules/ixgbe there is now modules/ix and modules/ixv - It will also be possible to make your static kernel with only one or the other for streamlined installs, or both.

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

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.

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 to the Intel ixgbe driver: - Split the driver into independent pf and vf loadables. This is in preparation for SRIOV support which will be following shortly. This also allows us to keep a seperate revision control over the two parts, making for easier sustaining. - Make the TX/RX code a shared/seperated file, in the old code base the ixv code would miss fixes that went into ixgbe, this model will eliminate that problem. - The driver loadables will now match the device names, something that has been requested for some time. - Rather than a modules/ixgbe there is now modules/ix and modules/ixv - It will also be possible to make your static kernel with only one or the other for streamlined installs, or both.

Various fixes to the stats in igb(4), ixgbe(4), and ixl(4). - Use hardware counters for ifnet stats in igb(4) when possible. This ensures these stats include packets that bypass the regular stack via netmap. - Don't derefence values off the end of the igb(4) VF stats structure. Instead, add a dedicated if_get_counter method for igb(4) VF interfaces. - Report missed packets on igb(4) as input queue drops rather than an input error. - Report bug_ring drop counts as output queue drops for igb(4) and ixgbe(4). - Export the buf_ring drop stats for individual rings via sysctl on ixgbe(4). - Fix a typo that in ixl(4) that caused output queue drops to be reported as input queue drops and input queue drops to be unreported.

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.

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

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!!

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 to the Intel ixgbe driver: - Split the driver into independent pf and vf loadables. This is in preparation for SRIOV support which will be following shortly. This also allows us to keep a seperate revision control over the two parts, making for easier sustaining. - Make the TX/RX code a shared/seperated file, in the old code base the ixv code would miss fixes that went into ixgbe, this model will eliminate that problem. - The driver loadables will now match the device names, something that has been requested for some time. - Rather than a modules/ixgbe there is now modules/ix and modules/ixv - It will also be possible to make your static kernel with only one or the other for streamlined installs, or both.

Update to the Intel ixgbe driver: - Split the driver into independent pf and vf loadables. This is in preparation for SRIOV support which will be following shortly. This also allows us to keep a seperate revision control over the two parts, making for easier sustaining. - Make the TX/RX code a shared/seperated file, in the old code base the ixv code would miss fixes that went into ixgbe, this model will eliminate that problem. - The driver loadables will now match the device names, something that has been requested for some time. - Rather than a modules/ixgbe there is now modules/ix and modules/ixv - It will also be possible to make your static kernel with only one or the other for streamlined installs, or both. Enjoy! Submitted by: jfv and erj
