New Revision: 343572
URL: https://svnweb.freebsd.org/changeset/base/343572

Log:
  Add support for Audio Sink and Audio Source profiles to sdpd(8).
  
  This allows user-space programs like virtual_oss(8) to act
  as a Bluetooth speaker device.
  
  MFC after:		1 week
  Sponsored by:		Mellanox Technologies
