cfg80211: Pass TDLS peer capability information in tdls_mgmt
While framing the TDLS Setup Confirmation frame, the driver needs to know if the TDLS peer is VHT/HT/WMM capable and thus shall construct the VHT/HT operation / WMM parameter elements accordingly. Supplicant determines if the TDLS peer is VHT/HT/WMM capable based on the presence of the respective IEs in the received TDLS Setup Response frame. The host driver should not need to parse the received TDLS Response frame and thus, should be able to rely on the supplicant to indicate the capability of the peer through additional flags while transmitting the TDLS Setup Confirmation frame through tdls_mgmt operations.
