This patch series fixes the Ethernet jumbo frames support for the SoCs
Armada 370, 380 and 385. Unlike Armada XP, the Ethernet controller for
this SoCs don't support TCP/IP checksumming with a frame size larger
than 1600 bytes.

This patches should be applied to the -stable kernels 3.8 and onwards.

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!

At first, I though this was an error in the Armada 38x datasheet (maybe
a sloppy copy/paster). Therefore I have checked on an DB-88F6820-GP
board and then I can confirm that the Armada 38x is also affected.
