Subject: au1000_eth.c: use ether_crc() from <linux/crc32.h>
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=8cd35da094bed8a41eb722c1d03eab24d57bf706;p=openwrt%2Fstaging%2Fblogic.git

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

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>
