Subject: [PATCH] ath10k: add mic bytes for pmf management packet
Date: Mon, 17 Jun 2019 15:37:59 +0800 [thread overview]
Message-ID: <1560757079-19266-1-git-send-email-wgong@codeaurora.org> (raw)
For PMF case, the action,deauth,disassoc management need to encrypt
by hardware, it need to reserve 8 bytes for encryption, otherwise
the packet will be sent out with error format, then PMF case will
fail.
After add the 8 bytes, it will pass the PMF case.
Tested with QCA6174 SDIO with firmware
WLAN.RMH.4.4.1-00005-QCARMSWP-1.
