Adaptive 11r feature that enables the AP to support FT-AKM without configuring the FT-AKM in the network. The AP will advertise non-FT akm with a vendor specific IE having Adaptive 11r bit set to 1 in the IE data. The AP also advertises the MDE in beacon/probe response. The STA should check the adaptive 11r capability if the AP advertises MDE in beacon/probe and adaptive 11r capability in vendor specific IE. If adaptive 11r capability is found, STA can advertise the FT equivalent of the non-FT AKM and connect with 11r protocol. Before sending probe request to the AP, the host driver intersects the csr_roam_profile akm with the akms advertised by the AP in the function csr_construct_rsn_ie(). Based on the intersection, RSN IE is constructed and this RSN IE will be sent over the association request frame. Add changes to fill FT-PSK akm selector if AP advertises PSK akm(00:0f:ac,4). If the AP advertises 802.1X akm, fill FT-802.1x akm(00:0f:ac,3). If the session is adaptive 11r connection, then copy the adaptive_11r flag to pe_session while sending join request. Populate the adaptive 11r vendor specific IE into association request frame. Change-Id: Iae6ea37787e96fd7cffca32fc4d9a33eb5772f26 CRs-Fixed: 2441337 |
