    SubjectRE: 2.2.x kernels missend odd-sized ICMP packets

    Can you all *PLEASE* report what cpu you have with these problems as well
    as your compiler and what cpu you selected in kernel compliation?

    It appears to be a checksumming problem, and Linux has asm optimizations
    for packet checksumming, so perhaps there is a bug in one of the
    checksumming routienes.. Davem?


    FYI-

    PPRO 2.2.3 compiled w/ GCC with PPRO as kernel cpu type: OK
    CELERON 300A 2.2.5 compiled w/ GCC with PPRO as kernel CPU type: OK
