Subject: [PATCH 05/12] ath11k: Add vdev start flag to disable hardware encryption
Date: Thu, 22 Jul 2021 00:20:22 +0300	[thread overview]
Message-ID: <20210721212029.142388-5-jouni@codeaurora.org> (raw)
In-Reply-To: <20210721212029.142388-1-jouni@codeaurora.org>

From: Seevalamuthu Mariappan <seevalam@codeaurora.org>

Firmware blocks all data traffic until the key is plumbed. But, with
software encryption mode, key is never plumbed to firmware. Due to this,
a traffic failure in software encryption mode has been observed. Hence,
firmware has introduced a flag to differentiate software encryption
mode. This flag can be passed during vdev_start command.

Enable WMI_VDEV_START_HW_ENCRYPTION_DISABLED flag in vdev_start command
to notify firmware to disable hardware encryption for a vdev. This is set
if raw mode software encryption is enabled.

Tested-on: IPQ8074 hw2.0 AHB WLAN.HK.2.4.0.1-01421-QCAHKSWPL_SILICONZ-1
