It is similar to infrastructure BSS, having an AP-like entity called PCP (PBSS Control Point), but it has few differences. For example, stations inside a PBSS can communicate directly, and the PCP role can be transferred between stations. This change adds PBSS support, and has 2 main parts: 1. When starting an AP, add an option to start as a PCP instead. This is implemented by a new PBSS flag which is passed as part of the cfg80211_ap_settings structure. 2. When connecting to a BSS, add an option to connect to a PCP instead of an AP. This is again implemented by a new PBSS flag, added to the cfg80211_connect_params structure.
