From c261bdf8acad56717cae233709808d8d9291ce36 Mon Sep 17 00:00:00 2001 From: Roland Vossen Date: Tue, 18 Oct 2011 14:03:04 +0200 Subject: [PATCH] brcm80211: smac: indicate severe problems to Mac80211 In case the hardware crashes, a reinitialization internal to the driver was performed. Since Mac80211 must be in the know of such an event as well, ieee80211_restart_hw() is now called.
