Performance drop on SFC interface (around 30%)

Hello netdev, we see a performance drop (about ~30%) on sfc driver (SFC9020) when performing netperf TCP maerts test. It seems it started from 4.7-rc0. Which commit/change could cause this regression? Any hints? I opened a bugzilla [0] where you can find images with results. [0]

ixgbe: cannot enable LRO

Hello everyone, does anybody have a problem with LRO on ixge (on latest 4.6-rc5)? I cannot find a way to enable it. On stable RHEL7.2 kernel everything works fine. I opened a bug report [0]. [0] https://bugzilla.kernel.org/show_bug.cgi?id=117291 Thanks! Ota signature.asc Description: PGP

[BUG] net: performance regression on ixgbe (Intel 82599EB 10-Gigabit NIC)

Hello netdev, I probably found a performance regression on ixgbe (Intel 82599EB 10-Gigabit NIC) on v4.4-rc3. I am able to see this problem since v4.4-rc1. The bug report you can find here [0]. Can somebody take a look at it? [0] https://bugzilla.redhat.com/show_bug.cgi?id=1288124 thanks, Ota

[BUG] bnx2x_config_vlan_mac called a NULL function pointer

Hello netdev, I probably found a bug in kernel-4.3.0-0.rc5 (bnx2x driver). So I opened new bug report in our bugzilla [0]. Michal Schmidt told me the best way to solve an upstream bug is to contact you directly to netdev list.. so here I am :). Can somebody take a look at it? [0]
