Log Message:
new: add a raw_threshold for raw mode.   this basically tells the driver
        to ignore inbound data sizes less than the threshold.  otherwise, 
        when connected to a video aal0 input the driver gives us a massive 
        stream of 56 byte mbufs each with one aal0 cell in it and the 
        system just can't keep up with it, especially if the socket buffer 
        size is large [it hangs until you turn off the video source].

fixes: when turning off a vc, try and check the freshest copy of the mode
        when seeing if we need to enter the "drain" state.   also, don't
        panic if we get unexpected rx interrupt on a VCI (instead make sure
        the VC is off, print a warning, and move on!).
