Hi Fred,
> This patch extends the current bluetooth socket option to add BT_VOICE.
> This is intended to choose voice data type at runtime. It only applies to SCO
> sockets.
> Incoming connections shall be setup during defered setup. Outgoing connections
> shall be setup before connect(). The desired setting is stored in the sco
> socket info.
> This patch declares needed members, modifies getsockopt() and setsockopt().
