Subject: hostapd: add support for per-BSS airtime configuration
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=e289f183476b486e6f9f9590013a5b98de54c762;p=openwrt%2Fstaging%2Fmkresin.git

hostapd: add support for per-BSS airtime configuration

Add support for per-BSS airtime weight configuration. This allows to set
a airtime weight per BSS as well as a ratio limit based on the weight.

Support for this feature is only enabled in the full flavors of hostapd.

Consult the hostapd.conf documentation (Airtime policy configuration)
for more information on the inner workings of the exposed settings.
