Yes, there's value in it. NFS can benefit greatly if you can stuff a
single read/write block into a single ethernet frame (rather than
splitting it across 3 or 4). It's also helpful for wringing maximum
throughput out of your network at higher speeds. Think about the
interrupt rate to send 1Gb/s with 1500B frames and compare that to
6000B frames. Even if your card is totally insane, you've just got 4
times more data out of one interrupt.

Check the manpages for the various network drivers...

GDB has a 'break' feature; why doesn't it have 'fix' too?
