[PATCH] au1000_eth.c: use ether_crc() from <linux/crc32.h>

To: jgarzik@pobox.com
Subject: [PATCH] au1000_eth.c: use ether_crc() from <linux/crc32.h>
From: Herbert Valerio Riedel <hvr@gnu.org>
Date: Mon May 1 15:37:09 2006 +0200
Cc: netdev@vger.kernel.org, linux-mips@linux-mips.org, sshtylyov@ru.mvista.com
Original-recipient: rfc822;linux-mips@linux-mips.org
Sender: linux-mips-bounce@linux-mips.org
since the au1000 driver already selects the CRC32 routines, simply replace
the internal ether_crc() implementation with the semantically equivalent
one from <linux/crc32.h>

Signed-off-by: Herbert Valerio Riedel <hvr@gnu.org>
