TCP checksum errors are not logged in any way on the 2.0.X kernels.
In fact, there are a whole bunch of places that packets can get dropped
in both kernels without getting counted as dropped in any statistics.
I've been thinking a bit about what we should do about this, but I
haven't reached any definite conclusions. If you want to check if
you are loosing packets to bad TCP checksums in 2.0.X I can give
you a little patch that sets up the 2.0.X kernel to report bad packets.
