Subject: [PATCH v2 1/2] ath11k: clear the keys properly via DISABLE_KEY
Date: Mon, 15 Nov 2021 11:04:40 +0100 [thread overview]
Message-ID: <20211115100441.33771-1-sven@narfation.org> (raw)
From: Karthikeyan Kathirvel <kathirve@codeaurora.org>
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")
