 By default, when FreeBSD is accepting a new connection, it tries to perform a role switch and become master.
 Some older Bluetooth devices which do not support role switching will not be able to connect.
-Since role switching is performed when a new connection is being established, it is not possible to ask the remote device if it supports role switching.

+Bridge interfaces also support monitor mode, where the packets are discarded after man:bpf[4] processing and are not processed or forwarded further.
 This can be used to multiplex the input of two or more interfaces into a single man:bpf[4] stream.

+For laptop users, it is usually desirable to configure the wireless device as a secondary which is only used when the Ethernet connection is not available.
 With man:lagg[4], it is possible to configure a failover which prefers the Ethernet connection for both performance and security reasons, while maintaining the ability to transfer data over the wireless connection.
 
 This is achieved by overriding the Ethernet interface's MAC address with that of the wireless interface.
