Hello!
I am thinking about advancing the ipv4/tcp_ecn knob in linux to
distinguish between ipv4 and ipv6 transport and enable ecn signaling
on outgoing ipv6 connections by default (for me, at least). I am
currently doing so with the help of iptables (echo 1 > tcp_ecn and -j
ECN --ecn-tcp-remove).
Any particular reason you aren't willing/able to just flip the
net.ipv4.tcp_ecn sysctl to turn it on for both? FWIW, that is what I
have done on netperf.org, with an eye towards seeing what ceases
working. Thusfar things seem OK. At least I've not had anyone contact
me to say "Hey! Why can't I reach netperf.org!" ...
happy benchmarking,
