OK, but do not limit it to FRTO, I think all TCP features should be handle'able this way. Actually, this is a problem with using an RTAX_* that is a bitmask or single binary. You need a "don't care" value, and thus effectively a trinary route entry state to do this properly. Right? In this way, you have a global default, but you can also FORCE something off per-route. People can work-around ECN-fux0red sites without obviating ECN completely. Or perhaps you can come up with another method by which to achieve this? > Okay, what about WESTWOOD? ... > What about tcp_westwood which is new? Just don't change sysctl numbers, even we keep them perfectly sync'd between 2.6.x and 2.4.x sources. - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
