Re: Asserting ECN from userspace?

And twiddling them, on a per stream basis, for a single packet, would
seem to require something more robust than setsockopt/getsockopt
(although that would work for udp streams)

With netfilter nf_queue you can construct a rule that passes packets
through user space and reinjects them.

I would suggest to just use that to modify the ECN bits.

I'm sure with reasonable google skills you can find some examples
how to do this on the web.
