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,
