If your mtu is much bigger than 8KB you will want to make sure you've got at
least afs 3.5 on each end, and you'll want to increase RX_JUMBOBUFFERSIZE.
Even with an 8KB mtu you can get some increase in performance by increasing
this, because you'll be getting more data per rx packet, and will have to do
less jumbogram unpacking.

CITI Tech Report 01-3, "Improving File Fetches in AFS," talks a bit about rx
mtu issues.
