   When sending out to a local peer, ethernet and point-to-point devices will
buffer the initial burst of packets with the local buffers draining at the
speed of the available link bandwidth, so I don't see why you would want to
do slow start in this case. This is different than the case of a congested
upstream circuit where you don't know about the congestion and have no
control over the buffering.
