ath10k: add report MIC error for sdio chip (47ed1b4e) · Commits · 戴 / test

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. Signed-off-by:
