Subject: Re: [PATCH net] codel: fix maxpacket/mtu confusion

I long ago dropped the maxpacket check and the statistic/statistic
collection from various test versions of codel in favor of either a
constant (1500 byte) check or none at all. There is always some level
of buffering underneath codel. I have always wanted the big
GRO/TSO/GRO superpackets to get peeled apart also - the present system
worked OK with ECN in most cases, but seemed  like it could get ugly
if we started dropping 64k worth of superpacket.
