From cd017f25e391dfabaca185bb4a5aefd02fd6c0ca Mon Sep 17 00:00:00 2001 From: Stanislaw Gruszka Date: Thu, 23 Dec 2010 15:12:30 +0100 Subject: [PATCH] iwlagn: fix scan tx antenna setting on 5Ghz band Looks that we do not set correctly antennas when scanning on 5Ghz band and when bluetooth is enabled, because priv->cfg->scan_tx_antennas[band] is only defined for IEEE80211_BAND_2GHZ. To fix we check band before limiting antennas to first one. This allow to remove hard coded cfg->scan_tx_antennas[band]. Signed-off-by: Stanislaw Gruszka Acked-by: Wey-Yi Guy Signed-off-by: John W.
