From 30433d3b9850140ceb801c5cc2013c7b408c33de Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Thu, 24 Sep 2015 18:14:55 +0200 Subject: [PATCH] iwlwifi: mvm: prevent multiple stations with the same address As the device (and parts of the driver) cannot deal with having the same MAC address for two stations (on two virtual interfaces), add some explicit code to prevent this case. Note that in practice this cannot happen since the device doesn't support operating with two AP/GO interfaces at the same time either, and other scenarios for this are, while not impossible, not going to happen in practice.
