Probably.
On the the "listening" side it may work to set it on the listen socket,
but probably not..
Hope I manage to spur a discussion around this, as I don't code myself...
Having the decision made by routing similar to how MSS & window sizes etc
can be decided surely makes most sense, but I would not bet that someone
finds this sufficiently interesting to implement it out of the void for
you.
But it should not be much more than adding a new value to RTM_METRICS, and
a dst_metrics() lookup at the appropriate place plus additions to iproute
to allow the value to be sent to the kernel, but there is complications in
that the current RTM_METRICS is all based arount integers while the
congestion control algorithms is all named by strings. But on the other
hand this probably should be changed for efficiency anyway if doing this
as doing a string based lookup for the congestion control algorithm on
each new tcp connection is probably not wanted.
