From: David Bauer Date: Sat, 27 Nov 2021 21:08:28 +0000 (+0100) Subject: hostapd: add OpenWrt specific statistic counters X-Git-Tag: v22.03.0-rc1~955 X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=16bcaa71faaef1462034bd410032409b18dc6430;p=openwrt%2Fopenwrt.git hostapd: add OpenWrt specific statistic counters This adds a new struct for storing statistics not (yet) tracked by hostapd regarding RRM and WNM activity. These statistics can be read using the get_status hostapd interface ubus method.
