Firmware will report flag with HTT_RX_IND_MPDU_STATUS_TKIP_MIC_ERR
if MIC error, the flag will be used in mac80211.
ieee80211_rx_h_michael_mic_verify will check the flag and start TKIP
countermeasures.
Now countermeasure tests pass both with WPA only and WPA2/WPA mixed
mode.
Tested with QCA6174 SDIO with firmware
WLAN.RMH.4.4.1-00007-QCARMSWP-1.
