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.

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.

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.

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.

static bool ixgbe_sfp_probe(struct adapter *);
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.

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.

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.

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 :)

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 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 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.

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 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.

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 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.

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.

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 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.

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 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.

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. 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.

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.

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 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.

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 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 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.

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.

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.

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 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 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.

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.

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.

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 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.

/* 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

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 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.

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.

A couple of changes: first, make header split on by default and remove from its dependency on LRO, my tests have shown that its always beneficial, even when doing bridging. Second, fix up a few problems in the statistics code, the adapter dependencies had gotten lost so some code that should only run on 82599 was always running, this resulted in bogus flow control numbers on 82598.

A few minor fixes: - add a moderation value to the Link vector - allow disabling HW RSC on the 82599 if LRO is not enabled. - correct error in the stats code - change optic type on the 82598 DA device Thanks to Andrew Boyer for the changes.

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.

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 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 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
