b43: fix frequency reported on G-PHY with /new/ firmware
commit 2fc68eb122c7ea6cd5be1fe7d6650c0beb2f4f40 upstream. Support for firmware rev 508+ was added years ago, but we never noticed it reports channel in a different way for G-PHY devices. Instead of offset from 2400 MHz it simply passes channel id (AKA hw_value). So far it was (most probably) affecting monitor mode users only, but the following recent commit made it noticeable for quite everybody: commit 3afc2167f60a327a2c1e1e2600ef209a3c2b75b7 Author: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Date: Tue Mar 4 16:50:13 2014 +0200 cfg80211/mac80211: ignore signal if the frame was heard on wrong channel Reported-by: Aaro Koskinen <aaro.koskinen@iki.fi> Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Tested-by: Aaro Koskinen <aaro.koskinen@iki.fi> Signed-off-by: John W.
