Subject: mac80211: check the correct bit for EMA AP
X-Git-Url: https://jxself.org/git/?a=commitdiff_plain;h=02b0989fc0337cb39b15c231bedc997e5cd9ed79;hp=02b0989fc0337cb39b15c231bedc997e5cd9ed79;p=carl9170fw.git

mac80211: check the correct bit for EMA AP

An AP supporting EMA (Enhanced Multi-BSSID advertisement) should set
bit 83 in the extended capabilities IE (9.4.2.26 in the 802.11ax D5 spec).
So the *3rd* bit of the 10th byte should be checked.
Also, in one place, the wrong byte was checked.
(cfg80211_find_ie returns a pointer to the beginning of the IE,
 so the data really starts at ie[2], so the 10th byte
 should be ie[12]. To avoid this confusion, use cfg80211_find_elem
 instead).
