    snmp: 64bit ipstats_mib for all arches · 4ce3c183
    Eric Dumazet authored
    /proc/net/snmp and /proc/net/netstat expose SNMP counters.
    
    Width of these counters is either 32 or 64 bits, depending on the size
    of "unsigned long" in kernel.
    
    This means user program parsing these files must already be prepared to
    deal with 64bit values, regardless of user program being 32 or 64 bit.
    
    This patch introduces 64bit snmp values for IPSTAT mib, where some
    counters can wrap pretty fast if they are 32bit wide.
