In secured mesh, the unicast mgmt frame is encrypted using the same key that used for encrypting the unicast data frame. This patch "ath9k_htc_firmware: fix the offset of CCMP header for mesh data frame" applied to open-ath9k-htc-firmware allows the ath9k_htc to be loaded without "nohwcrypt=1". Unfortunately, this is not working and we still need CCMP encryption of transmitted management frames to be done in software. So this patch allows the software encryption for transmitted management frame to be done in software but remain the hardware decryption for received management frame. This patch is tested with the following hardwares: - TP-Link TL-WN821N v3 802.11n [Atheros AR7010+AR9287] - AR9271 802.11n and managed to work with peer mesh STA equipped with ath9k.
