I am not sure 64K GRO packets that must be segmented are going to be
faster than 22K packets without segmentation at all (TSO path on xmit)

Indeed that is a tough call, but I think conceptually the 64K
case is much nicer than a sysctl that gets magically turned off.

Also at some point we'll want to do >64K GRO/GSO too so we'll
have to face this complexity one day.

Not sure how this is possible with the IP datagram length limit. (Am I
missing something, like pkt chaining?)
