There is no excuse these days for stuff not to be ECN aware. That GREATLY =
mitigates things as it makes hosts aware pretty much immediately that there=
is congestion and they don't have to wait for a lost packet to time out. =
I brought it up to a Brocade engineer once asking for the option to set ECN=
rather than drop the packet and he said "nobody uses it". I told him nobo=
dy uses it because you don't have the feature available. How can anyone us=
e it if you don't have the feature?
