[PATCH] AMD Au1xx0: fix ethernet TX stats

With Au1xx0 Ethernet driver, TX bytes/packets always remain zero.

The problem seems to be that when packet has been transmitted, the
length word in DMA buffer is zero.

Attached is a patch that updates the TX stats when a buffer is fed to
DMA.

The initial 2.4 patch was posted to linux-mips@linux-mips.org by
Thomas Lange 21 Jan 2005.
