Subject: hostapd: add support for static airtime policy configuration
X-Git-Tag: v21.02.0-rc1~1084
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=edb93eda161218af49393e2f2c68b87d5538a658;p=openwrt%2Fstaging%2Fchunkeey.git

hostapd: add support for static airtime policy configuration

* Add support for passing airtime_sta_weight into hostapd configuration.
* Since that commit it is possible to configure station weights. Set higher
  value for larger airtime share, lower for smaller share.

I have tested this functionality by modyfing /etc/config/wireless to:

config wifi-device 'radio0'
	...
        option airtime_mode '1'

config wifi-iface 'default_radio0'
	...
        list airtime_sta_weight '01:02:03:04:05:06 1024'

Now, when the station associates with the access point it has been assigned
a higher weight value.
