    new-reno was artifically limiting the max number of in-transit 
    packets to 4.  This is probably why the USB ethernet worked
    with 4.3, but it destroyed TCP performance for everything else
    and was removed.

    I don't think there is kernel solution to the USB problems, short
    of fixing the driver (if that's even possible).  The packets are
    being sent from the server and the only thing the client has
    control over is the receive window advertisement.  You could artifically
    reduce the window advertisement on the client to deal with lots of small
    packets but it would destroy performance for larger packets / data
    streams.
