For startes, can you fix
oss.software.ibm.com so it respects ECN?

In regards to policing SYNs i am not sure what additional
value you provide to the mechanisms currently available under
2.4 ingress traffic policing; the simplest example we provided
was on SYN policing albeit for DoS prevention.
Since i refuse to turn off ECN, i cant access your web page
You can use the skbmark to prioritize based on policies
installed on the ingress and drop early ...

Incase you are using this scheme already you should stick to the
ingress policer which uses a dual Token Bucket not what netfilter uses..

cheers,
jamal
