From: Tamizh chelvam <[email protected]> Set peer's management frame protection flag in peer assoc command, this setting will enable/disable encrytion of management frames in fw.
Setting of this flag is based on whether MFP is enabled/disabled at STA and a firmware feature flag ATH10K_FW_FEATURE_MFP_SUPPORT. This is because only firmwares 10.1.561 and above have support for MFP.
