can I ask again why we should be doing this. Especially for the FdOBEX
transport this is pointless. You are getting a file descriptor in the
first place. It does not have to be a socket.

And in the case this is really a socket, then you can just use SO_TYPE
to read the current type of the socket.

If it is not a socket, then it needs to treated as stream anyway.

No. Ever tried that on the linux USB gadget implementation in Linux? If a FD 
is not pointing to a socket, it can still point to a device file of whatever 
kind. You SO_TYPE won't completely help here. You can try any amount of 
guessing but isn't it easier if the application just tells you? OTOH, the 
application could just use a custom transport, then.
