Kris reports that this leads to significant performance improvements
in loopback benchmarking with TCP and UDP for throughput:
RXCSUM RXCSUM+TXCSUM
TCP 15% 37%
UDP 10% 74%
More like 24% instead of 74% actually, the sender and receiver had become
unbalanced in that test.
That makes more sense -- I was surprised to see such a large win on UDP.
Thanks for the update.
