Hi

The already-existing PIE Linux code maintained at
ftp://ftpeng.cisco.com/pie/ does not support ECN. Studying the interaction
of ECN and AQM algos is probably of interest of some of us. I have added
ECN support to PIE Linux code and have given it some basic sanity tests.

The modified code is available at
http://heim.ifi.uio.no/naeemk/research/PIE/

I would appreciate any feedback.

Regards,
Naeem
