I built a Wily test kernel with a cherry-pick of commit 50a9eea from mainline. The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1528466/ Can you test this kernel and confirm it resolves this bug? Also, commit 50a9eea was applied to mainline in v4.4-rc2. Commit 50a9eea states that it fixes commit facc9699f0, which was added to mainline in v4.2-rc1. That is how this bug was introduced in to Wily and the linux-lts-wily kernels. In addition, the file that is changed by commit 50a9eea is: drivers/net/ethernet/mellanox/mlx5/core/en_main.c This file was not added until v4.2-rc1 by commit f62b8bb. I'd just like to confirm you are only requesting this fix in Wily and the HWE kernels in Trusty? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1528466 Title: Mellanox ConnectX4 MTU limits: max and min Status in linux package in Ubuntu: In Progress Status in linux-lts-vivid package in Ubuntu: Incomplete Status in linux-lts-wily package in Ubuntu: In Progress Status in linux source package in Vivid: Incomplete Status in linux source package in Wily: In Progress Bug description: Max MTU limit should be 9978 Tested on Ubuntu 14.04.4 daily build, this issue exist also in 15.10. reproduce # ifconfig p2p1 mtu 9000000 SIOCSIFMTU: Invalid argument # dmesg [62898.559808] mlx5_core 0000:20:00.0 p2p1: mlx5e_change_mtu: Bad MTU (9000000) > (10000) Max [63058.512668] command failed, status bad parameter(0x3), syndrome 0x648afc Upstream commit that fix the issue commit 60825c35bf023553f8524f6695f176236e54df97 Author: Doron Tsur <dor...@mellanox.com> Date: Thu Nov 12 19:35:27 2015 +0200 net/mlx5e: Max mtu comparison fix On change mtu the driver compares between hardware queried mtu and software requested mtu.
