From 30d9b4a58bc168620eed0fc6d90b2f05cd02a462 Mon Sep 17 00:00:00 2001 From: Luciano Coelho Date: Wed, 11 Apr 2012 11:07:28 +0300 Subject: [PATCH] wlcore/wl12xx: move MAC address reading operation to lower driver Different chip families have the factory MAC address written in different places. Add a new hardware operation to read the MAC address, if available.
