Subject: [PATCH 2/5] ath10k: add handler for HTT_T2H_MSG_TYPE_SEC_IND event
Date: Fri, 26 Apr 2019 09:41:08 +0300	[thread overview]
Message-ID: <1556260871-2919-3-git-send-email-kvalo@codeaurora.org> (raw)
In-Reply-To: <1556260871-2919-1-git-send-email-kvalo@codeaurora.org>

From: Wen Gong <wgong@codeaurora.org>

Add the handler for HTT_T2H_MSG_TYPE_SEC_IND event from firmware, which stores
PN for replay check implemented in the following patch.

Tested on QCA6174 SDIO with firmware WLAN.RMH.4.4.1-00007-QCARMSWP-1.
