Subject: mac80211: remove 80+80 MHz rate reporting
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=f89903d53f4d39577be98940f7cfa49d66f86db5;p=linux-beck.git

mac80211: remove 80+80 MHz rate reporting

These rates are treated the same as 160 MHz in the spec,
so it makes no sense to distinguish them. As no driver
uses them yet, this is also not a problem, just remove
them.
