You should add a Fixes: tag to each commit to indicate which commit is
being fixed by your patches.

Also, I was a bit surprised by your statement that Armada 38x is also
affected by the problem, since Armada 38x is more recent than Armada
XP. but indeed, according to the Armada 38x datasheet:

  IPv4 and TCP/UDP over IPv4/IPv6 checksum generation on transmit
  frames for standard Ethernet packet size

While the Armada XP datasheet says:

  Long frames transmission (including jumbo frames), with
  IPv4/v6/TCP/UDP checksum generation

So it seems like you're right about this!

Best regards,

Thomas
