For the last couple of days, linux-next booting on a few of our Power
partitions (but not all) have produced this error (over and over):

ibmveth 3000000b: eth0: tx: h_send_logical_lan failed with rc=-4

Linus' tree seems to boot fine on these partitions.  The only commit
directly affecting ibmveth in linux-next is b9367bf3ee6d ("net: ibmveth:
convert to hw_features") which first appeared in next-20110421 which is
also the first one that failed.

Please test the following patch. It's just a blind guess, as this error
is not descriptive.

net: ibmveth: force reconfiguring checksum settings on startup

Commit b9367bf3ee6d ("net: ibmveth: convert to hw_features") accidentally
removed call to ibmveth_set_csum_offload() in ibmveth_probe(). Put the
call back where it was, but with additional error checking provided
by ibmveth_set_features().
