[Discuss-gnuradio] initial raw frame transmit code try #2 checked in

[George Nychis]

Okay I checked in some new raw frame transmit code in again.  This is visible in 
revision 4965.

The one thing that I wasn't sure of, is where to set the start of burst and end 
of burst flags.  Can a single frame have multiple burst and end of bursts?

Basically I don't know what defines our burst... all of the fragments which 
define a frame, or USB bus.

The way it's coded now, a burst is a frame.  Changing it to the USB bus should 
be fairly easy.

If it's defined by the USB bus, do we want to create a burst worth of packets, 
send them, create another burst, send them ... or create them all at once and 
send them burst by burst?

Basically I wanted to get something in ASAP so you could look over my packet 
creation method using the pmt u8 vector and make sure I was doing all of that 
okay.  If I have to change some semantics, no problem!
