Subject: [PATCH] wl12xx: reset 5ghz num channels on hw init
Date: Mon, 10 Jan 2011 23:04:04 +0200 [thread overview]
Message-ID: <1294693444-30807-1-git-send-email-arik@wizery.com> (raw)
The number of 5ghz channels is set to 0 when 11a is not supported in the
NVS file. When a single rmmod/insmod of wl12xx_sdio this leads to a
supported band (5ghz) with 0 supported channels, which mac80211
considers illegal.
Fix this by always resetting the number of supported 5ghz channels
before the HW is registered.
