Thanks, that makes a lot more sense.  Just to confirm, the second
part of the sender dump should be the one showing GRO, right?


OK, although this bug should only manifest itself if aggregation
occurs, which apparently isn't the case according to the dump.


BTW, when you're testing without GRO are you disabling GRO with
ethtool or loading an ixgbe driver without the patch? If the latter
please try it with ethtool (even if you don't have a patched ethtool
that supports GRO you can always disable RX checksums).

Maybe I just stuffed up the ixgbe patch.

Thanks,
