    Subject[PATCH AUTOSEL 5.1 016/219] ath10k: Fix encoding for protected management frames
    Date
    From: Rakesh Pillai <pillair@codeaurora.org>

    [ Upstream commit 42f1bc43e6a97b9ddbe976eba9bd05306c990c75 ]

    Currently the protected management frames are
    not appended with the MIC_LEN which results in
    the protected management frames being encoded
    incorrectly.

    Add the extra space at the end of the protected
    management frames to fix this encoding error for
    the protected management frames.

    Tested HW: WCN3990
    Tested FW: WLAN.HL.3.1-00784-QCAHLSWMTPLZ-1

    Fixes: 1807da49733e ("ath10k: wmi: add management tx by reference support over wmi")
