From 299c2ceafa1c8382e0e7e7a8706ea0b56dcc3261 Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Sat, 13 Jul 2013 11:39:48 +0000 Subject: [PATCH] mac80211: tweak mac address allocation Apparently there are some broken devices out there that have the local bit already set in the factory MAC address. Move the | 0x2 over to the other side of the xor operation to fix this without affecting devices with proper addresses.
