any chance to see update/implementation on-topic ?
even w/o say PURPLE queues ( f-GREEN and s-GREEN are not ECN-dependant) there was TOO much tech in modern networking that fail to work or Severely underperfrom w/o ECN support(both support, requence, enforcement, enabled/toggled in all kinds/points of gear/networks).
its rather "simple update" to ROS, not demanding newer kernel or newer code, just extra checkbox(like say "routing cache" enabling or one for "syncookie" or for "RP Filter"(if MT decide to implement all 3 options for)in option for ROS to be aware in bootime about dat option/switch to perform according to. so there was no need to wait for ROS7 or much manpower/hours of work needed i suppose.
for anyone new to topic:
https://en.wikipedia.org/wiki/Explicit_ ... tification
as basic introduction.
same about "enabling/disabling timestamps" - sometimes they Should be disabled, sometimes they are Lifesavers so there was "always should option about" such things in general.
