Elbert,

The ehea driver in RHEL 5.2 logs packets with a bad TCP checksum in the way
you
see in your logs. As this is obviously too noisy, the driver has meanwhile
been
modified not to log TCP checksum errors but just incremented the respective
statistics counters. RHEL 5.3 will contain this patch. Mainline kernel
contains
the patch since 2.6.24.

Regards
Thomas
