Bridging packets, which don't come from the IP stack, won't have
CHECKSUM_HW or similar set in the SKB checksum field. Therefore
the chip won't be told to checksum the packet on transmit.
The firmware will not mess with the packet contents at all unless
it is told to do so, and in this case (as described) it won't.

I'd like to see a real errata report supporting such a claim.
