Subject: [PATCH] count tg3 rx_discards stat for /proc/net/dev
Date: Wed, 12 May 2004 15:02:16 +1000	[thread overview]
Message-ID: <40A1AFD8.D5593759@melbourne.sgi.com> (raw)

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.
