XL driver checksum producing corrupted but checksum-correct packets

[Matthew Dillon]

    Well, I tried to tcpdump a session.  I managed to hit the error three
    times but in all three cases the tcpdump on the server dropped the
    particular packet I was looking for.  I'm only able to get a 70%
    retention rate in the tcpdump output on the server... its just trying
    to record too much for the machine to handle at the rate the NFS requests
    are coming in.

    I'm going to give up trying to characterize the corruption for now.
    It could very well be the PCI latency timer as previously discussed
    but I can't test that right now.
