From bc2ab3b850a8c563b3910f396e5f0753ce855134 Mon Sep 17 00:00:00 2001 From: Luciano Coelho Date: Wed, 8 May 2013 12:54:56 +0300 Subject: [PATCH] wl18xx: use locally administered MAC address if not available from fuse In some R&D chips, the device may be left untrimmed and with the MAC address missing from fuse ROM. In order to support those devices, apply a random locally administered MAC address instead.
