No, it uses tap(4) interface directly with an L2CAP socket. BNEP is in the
Although a bnep(4) interface could make some aspects more efficient
(context switch is expensive on some platform?), it could also make more
difficulty (a kernel device cannot make a record for SDP) and would be
more complex overall.
I think for the lower data rate of a Bluetooth device its not so bad for
now, but perhaps a busy NAP on small hardware might be a different matter
(needs to copy packet to multiple sockets)
