Wake up and smell the new millennium. Networking has all grown up while you were asleep. We have these new cool things called "switches", NICs with bigger buffers,...
The 8k limit that you find in RFC1094 was an ad-hoc "limit" based purely on testing using pre-1989 hardware. AFAIK most if not all of the commercial vendors (Solaris, AIX, Windows/Hummingbird, EMC and Netapp) are all currently setting the defaults to 32k block sizes for both TCP and UDP. Most of them want to bump that to a couple of Mbyte in the very near future.
Linux 2.4 didn't have support for anything beyond 8k. BSD sets 32k for TCP, and 8k for UDP for some reason.
