Subject: RE: [PATCH 1/2] mac80211/wlcore: Add ieee80211_hw variable to
 get_expected_throughput

Hi,
1) Sorry about the change log, I will try to be clearer next time.

2+3) The issue is not that the station is not known, it's that wl_sta->wl was null. 
wl member is now completely removed from wl_sta (PATCH 2/2) and hw is sent directly from mac80211 to the driver (so it can get hw->priv).

4) Sorry, I just saw now that everything has a space before the line. I used checkpatch.pl and it was ok. I will be more careful next time.

BR,
Max
