X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6f7a8d26e2668e00de524d3da0122a4411047dd2;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

mac80211: send statistics with delete station event

Use the new cfg80211_del_sta_sinfo() function to send the
statistics about the deleted station with the delete event.
This lets userspace see how much traffic etc. the deleted
station used.
