ath11k: clear the keys properly via DISABLE_KEY
DISABLE_KEY sets the key_len to 0, firmware will not delete the keys if key_len is 0. Changing from security mode to open mode will cause mcast to be still encrypted without vdev restart. Set the proper key_len for DISABLE_KEY cmd to clear the keys in firmware. Tested-on: IPQ6018 hw1.0 AHB WLAN.HK.2.5.0.1-01100-QCAHKSWPL_SILICONZ-1 Fixes: d5c65159f289 ("ath11k: driver for Qualcomm IEEE 802.11ax devices") Reported-by: Sven Eckelmann <sven@narfation.org> Signed-off-by: Karthikeyan Kathirvel <kathirve@codeaurora.org> [sven@narfation.org: split into separate patches, clean up commit message] Signed-off-by: Sven Eckelmann <sven@narfation.org> Signed-off-by: Kalle Valo <kvalo@codeaurora.org> Link: https://lore.kernel.org/r/20211115100441.33771-1-sven@narfation.org
