From 1f04493123763f5b8bc6d5de9aed0222345c052c Mon Sep 17 00:00:00 2001 From: Daniel Drake Date: Thu, 24 Dec 2009 08:11:24 +0000 Subject: Fix MAC address access in 3c507, ibmlana, pcnet32 and libertas Commit f001fde5eadd915f4858d22ed70d7040f48767cf changed net_device.dev_addr from a 32-byte array to a pointer. I found 4 ethernet drivers which rely on sizeof(dev_addr), which are now only copying 4 bytes of the address information on 32bit systems. Fix them to use ETH_ALEN.
