Subject: mac80211: fix dot11MulticastTransmittedFrameCount tested address
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=85b89af07d509531cbbb51adb9ec65f90f304473;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

mac80211: fix dot11MulticastTransmittedFrameCount tested address

dot11MulticastTransmittedFrameCount should be updated according
to the DA, which might be different from A1. Checking A1 results
in the counter being 0 in case of station, as to-DS data frames
use A1 for the BSSID.

This behaviour is defined in state machines, specifically in the
sta_tx_dcf_3.1d(10) description of 802.11-2012.
