From 75e0de13631e115768a97131a2d7f5259217512d Mon Sep 17 00:00:00 2001 From: Carsten Otte Date: Thu, 22 Jul 2010 23:15:04 +0000 Subject: qeth: Clear mac_bits field when switching between Layer 2 and Layer 3 This patch fixes a problem that occurs when switching from layer 3 to layer 2 mode. Resetting this mac_bits makes sure that we retrieve our mac address from the card, otherwise the interface simply would'nt work.
