Subject: mac80211: indicate admission control in TX queue parameters
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=908f8d07e9774c2476e0683f6a0ce50562a2da45;p=openwrt%2Fstaging%2Fblogic.git

mac80211: indicate admission control in TX queue parameters

Some driver implementations need to know whether mandatory
admission control is required by the AP for some ACs. Add
a parameter to the TX queue parameters indicating this.

As there's currently no support for admission control in
mac80211's AP implementation, it's only ever set for the
client implementation.
