Comment 16 for bug 1854842

Hi Mohammad,

Can you double check that you tested with the 4.15.0-87-generic kernel from -proposed with the following uname string?

4.15.0-87-generic #87-Ubuntu SMP Fri Jan 31 19:32:37 UTC 2020

You can verify that the patches have landed in the kernel by looking at the git tree:

Checkout the code, switch to 4.15.0-87-generic tag:

$ git clone git://kernel.ubuntu.com/ubuntu/ubuntu-bionic.git
$ git checkout Ubuntu-4.15.0-87.87

Look at the git log history for the commits:

$ git log --oneline --grep "net/mlx5e: Rx, Fixup skb checksum for packets with tail padding"
d1a32cb24dfe net/mlx5e: Rx, Fixup skb checksum for packets with tail padding
$ git log --oneline --grep "net/mlx5e: Rx, Fix checksum calculation for new hardware"
786fb87b8f55 net/mlx5e: Rx, Fix checksum calculation for new hardware

Look at what version they are tagged in:

$ git describe --contains d1a32cb24dfe
Ubuntu-4.15.0-87.87~459

$ git describe --contains 786fb87b8f55
Ubuntu-4.15.0-87.87~458

Looking at the commits themselves:

$ git show d1a32cb24dfe
https://paste.ubuntu.com/p/yWs3tBqywK/
$ git show 786fb87b8f55
https://paste.ubuntu.com/p/byj34bPFjZ/

Note that:
- d1a32cb24dfe in the Ubuntu Bionic tree is 0aa1d18615c163f92935b806dcaff9157645233a upstream.
- 786fb87b8f55 in the Ubuntu Bionic tree is db849faa9bef993a1379dc510623f750a72fa7ce upstream.

I cross checked the backported commits with the upstream ones again, and they appear correct.

Can you please re-rest and double check you are running the 4.15.0-87-generic kernel from -proposed?

Thanks,
Matthew
