From 2ee8382fc6c763c76396a6aaff77a27089eed3aa Mon Sep 17 00:00:00 2001 From: Arend van Spriel Date: Sat, 10 Aug 2013 12:27:24 +0200 Subject: [PATCH] brcmfmac: ignore IF event if firmware indicates it Not every IF event from the firmware needs to result in a related interface, netdev or wdev, on the host. This is indicated in the event message. Handle that flag and effectively ignore the firmware event.
