Jeff Kirsher says: ==================== 10GbE Intel Wired LAN Driver Updates 2015-12-29 This series contains updates to ixgbe and ixgbevf. William Dauchy provides a fix for ixgbevf that was implemented for ixgbe, commit 5d6002b7 ("ixgbe: Fix handling of NAPI budget when multiple queues are enabled per vector"). The issue was that the polling routine would increase the budget for receive to at least 1 per queue if multiple queues were present, which resulted in receive packets being processed when the budget was 0. Emil provides minor cleanups for ixgbevf, one being that we need to check rx_itr_setting with == and not &, since it is not a mask. Added QSFP PHY support in ixgbe to allow for more accurate reporting of port settings. Fixed the max RSS limit for X550 which is 63, not 64. Veola fixes ixgbe ethtool reporting of backplane type interfaces as 1000/10000baseT link modes, instead, report the media as KR, KX or KX4 based on the backplane interface present. Mark cleans up redundancy in the setting of hw_enc_features that makes it appear that X550 has more encapsulation features than other devices. Also do not set NETIF_F_SG any longer since that is set by the register_netdev() call. Also fixed the X550EM_x revision check, which needs to check a value, not just a bit. Alex Duyck fixes additional bugs in ixgbe_clear_vf_vlans(), one being that the mask was using a divide instead of a modulus, which resulted in the mask bit being incorrectly set to 0 or 1 based on the value of the VF being tested. Alex also found that he was not consistent in using the "word" argument as an offset or as a register offset, so made the code consistently use word as the offset in the array. v2: dropped patch 8 of the original series, as it was undoing a part of the fix Alex Duyck was doing in patch 9 of the original series. Dropped based on feedback from Emil (the author). ==================== Signed-off-by:

Sathya Perla says: ==================== be2net: patch set The following patch set contains some feature additions, code re-organization and cleanup and a few non-critical fixes. Pls consider applying this to the net-next tree. Thanks. v3 changes: add a default case to the switch statement in patch 5 to satisfy the compiler (-Wswitch). v2 changes: replaced an if/else block that checks for error values with a switch/case statement in patch 5. Patch 1 fixes VF link state transition from disabled to auto that did not work due to an issue in the FW. This issue could not be fixed in FW due to some backward compatibility issues it causes with released drivers. The issue has been fixed by introducing a new version (v2) of the cmd from 10.6 FW onwards. This patch adds support for v2 version of this cmd. Patch 2 reports a EOPNOTSUPP status to ethtool when the user tries to configure BE3/SRIOV in VEPA mode as it is not supported by the chip. Patch 3 cleansup FW flash image related constant definitions. Many of these definitions (such as section offset values) were defined in decimal format rather than hexa-decimal. This makes this part of the code un-readable. Also some defines related to BE2 are labeld "g2" and defines related to BE3 are labeled "g3". This patch cleans up all of this to make this code more readable. Patch 4 moves the FW cmd code to be_cmds.c. All code relating to FW cmds has been in be_cmds.[ch], excepting FW flash cmd related code. This patch moves these routines from be_main.c to be_cmds.c. Patch 5 adds a log message to report digital signature errors while flashing a FW image. From FW version 11.0 onwards, the FW supports a new "secure mode" feature (based on a jumper setting on the adapter.) In this mode, the FW image when flashed is authenticated with a digital signature. Patch 6 removes a line of code that has no effect. Patch 7 removes some unused variables. Patch 8 fixes port resource descriptor query via the GET_PROFILE FW cmd. An earlier commit passed a specific pf_num while issuing this cmd as FW returns descriptors for all functions when pf_num is zero. But, when pf_num is set to a non-zero value, FW does not return the port resource descriptor. This patch fixes this by setting pf_num to 0 while issuing the query cmd and adds code to pick the correct NIC resource descriptor from the list of descriptors returned by FW. Patch 9 adds support for ethtool get-dump feature. In the past when this option was not yet available, this feature was supported via the --register-dump option as a workaround. This patch removes support for FW-dump via --register-dump option as it is now available via --get-dump option. Even though the "ethtool --register-dump" cmd which used to work earlier, will now fail with ENOTSUPP error, we feel it is not an issue as this is used only for diagnostics purpose. Patch 10 bumps up the driver version. ==================== Signed-off-by: -

The VF link state setting transition from "disable" to "auto" does not work due to a bug in SET_LOGICAL_LINK_CONFIG_V1 cmd in FW. This issue could not be fixed in FW due to some backward compatibility issues it causes with some released drivers. The issue has been fixed by introducing a new version (v2) of the cmd from 10.6 FW onwards. In v2, to set the VF link state to auto, both PLINK_ENABLE and PLINK_TRACK bits have to be set to 1. The VF link state setting feature now works on Lancer chips too from FW ver 10.6.315.0 onwards. Signed-off-by:

When I had rewritten the code for ixgbe_clear_vf_vlans() it looks like I had transitioned back and forth between using word as an offset and using word as a register offset. As a result I honestly don't see how the code was working before other than the fact that resetting the VLANs on the VF like didn't do much to clear them. Another issue found is that the mask was using a divide instead of a modulus. As a result the mask bit was incorrectly being set to either bit 0 or 1 based on the value of the VF being tested. As a result the wrong VFs were having their VLANs cleared if they were enabled. I have updated the code so that word represents the offset in the array. This way we can use the modulus and xor operations and they will make sense instead of being performed on a 4 byte aligned value. I replaced the statement "(word % 2) ^ 1" with "~word % 2" in order to reduce the line length as the line exceeded 80 characters with the register name inserted. The two should be equivalent so the change should be safe. Reported-by:

X550 allows for up to 64 RSS queues, but the driver can have max of 63 (-1 MSIX vector for link). On systems with >= 64 CPUs the driver will set the redirection table for all 64 queues which will result in packets being dropped. Signed-off-by:

Clean up minor redundancy in the setting of hw_enc_features that makes it appears that X550 uniquely has more encapsulation features than other devices. The driver only supports one more feature, so make it look that way. No longer set NETIF_F_SG since that is set by the register_netdev call. Thanks to Alex Duyck for noticing this slight confusion.

With this patchset, looks the performance penalty from eBPF decreased a lot, see the following test: 1) run 'tools/biolatency' of bcc before running block test; 2) run fio to test block throught over /dev/nullb0, (randread, 16jobs, libaio, 4k bs) and the test box is one 24cores(dual sockets) VM server: - without patchset: 607K IOPS - with this patchset: 1184K IOPS - without running eBPF prog: 1492K IOPS TODO: - remove the per-hashtable atomic counter V2: - fix checking on buckets size V1: - fix the wrong 3/3 patch ==================== Signed-off-by: -

The per-hashtable spinlock is used for protecting bucket's hlist, and per-bucket lock is just enough. This patch converts the per-hashtable lock into per-bucket spinlock, so that contention can be decreased a lot. Signed-off-by:

Newer firmware will return the ring group resource when we call hwrm_func_qcaps(). To be compatible with older firmware, use the number of tx rings as the number of ring groups if the older firmware returns 0. When determining how many rx rings we can support, take the ring group resource in account as well in _bnxt_get_max_rings(). Divide and assign the ring groups to VFs. Signed-off-by:

We need to keep track of all resources, such as rx rings, tx rings, cmpl rings, rss contexts, stats contexts, vnics, after we have divided them for the VFs. Otherwise, subsequent ring changes on the PF may not work correctly. We adjust all max resources in struct bnxt_pf_info after they have been assigned to the VFs. There is no need to keep the separate max_pf_tx_rings and max_pf_rx_rings. When SR-IOV is disabled, we call bnxt_hwrm_func_qcaps() to restore the max resources for the PF. Signed-off-by:

The hardware resources required to enable NTUPLE varies depending on how many rx channels are configured. We need to make sure we have the resources before we enable NTUPLE. Add bnxt_rfs_capable() to do the checking. In addition, we need to do the same checking in ndo_fix_features(). As the rx channels are changed using ethtool -L, we call netdev_update_features() to make the necessary adjustment for NTUPLE. Calling netdev_update_features() in netif_running() state but before calling bnxt_open_nic() would be a problem. To make this work, bnxt_set_features() has to be modified to test for BNXT_STATE_OPEN for the true hardware state instead of checking netif_running(). Signed-off-by:
