I'd like it very much if we could co-ordinate our efforts. I've had several folk volunteer their efforts, could use more. Also... Over the weekend, Dan Siemons uncovered a possible bad interaction between ECN and the default pfifo_fast qdisc in Linux. http://www.coverfire.com/archives/2011/03/13/pfifo_fast-and-ecn/ Perhaps some people could look into this, determine the extent that this is a real problem (it seems very bad to me that acks would get tossed into different queues based on interpreting mmc instead of ecn) and figure out where the right place(s) are for a patch? -- Dave Taht http://nex-6.taht.net
