commit 174a64226afe86982d6283aa3d4477da85ecf8f2
Author: Nathan Scott <nathans@xxxxxxxxxx>

    Transition Linux kernel /proc/net/snmp metrics to 64 bits
    
    The kernel exports these values as 64 bit these days, whereas
    we extract them as 64 bit and at the last minute fib and say
    they're 32 bits.  This is a more noticable problem on 64 bit
    big endian hosts, where that final transition often truncates
    to zero.  As a result, test qa/216 fails there.
    
    Adds in a logrewrite rule and test qa/827 to exercise it all.
