Subject: cfg80211: add bitrate for 20MHz MCS 9
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=8fdd136f2200e6b7237e7e48453f4a591d768e3e;p=linux-beck.git

cfg80211: add bitrate for 20MHz MCS 9

Some drivers (ath10k) report MCS 9 @ 20MHz, which
technically isn't defined. To get more meaningful value
than 0 out of this however, just extrapolate a bitrate
from ratio of MCS 7 and 9 in channels where it is allowed.
