From 9cbda726bb283d60cd4f34a3a9da8b5b48a46b0f Mon Sep 17 00:00:00 2001 From: Hauke Mehrtens Date: Tue, 10 May 2011 23:31:34 +0200 Subject: [PATCH] MIPS: BCM47xx: Fix MAC address parsing. Some devices like the Netgear WGT634u are using minuses between the blocks of the MAC address and other devices are using colons to separate them.
