ath10k: add mic bytes for pmf management packet (83ac2601) · Commits · 戴 / test

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. Signed-off-by:
