G'day,
This small patch makes the rx_discards stat count towards the receive
error count visible in /proc/net/dev and thus in the output of ifconfig.
This stat is rarely non-zero unless you use multiple cards on the same
PCI bus under heavy load; but when it does happen you really want to
know about it.
