By now there is no possibility to know supported features by kernel in case of bnep. Ioctls allows only to add connection, delete connection, get connection list, get connection info. Adding connection if it's possible (establishing network device connection) is equivalent to starting bnep session. Bnep session handles data queue of transmit, receive messages over bnep channel. It means that if we add connection the received/transmitted data will be parsed immediately. In case of get bnep features we want to know before session start, if we should leave setup data on socket queue and let kernel to handle with it, or in case of no setup handling support, if we should pull this message and handle setup response within user space.
