    From a quick look at bnx2.c, it seems that the driver gives the NIC
    (firmware?) a block of memory to DMA stats into, and just reads from
    that memory in its get_stats method. So if you're seeing wonky stats
    from the NIC intermittently, my best guess would be that firmware is
    occasionally writing junk into the stats block.
