One has to ask why. I assume this is based on an assumption that you can 
get 1Gbps out of some other device, which is surely misplaced. I've 
never seen a gigabit interface attached to a server doing more than 
about 120Mbps while doing anything useful with the data involved (cue 
disagreement from people who just do disk benchmarks using `dd 
if=/dev/zero...`)

Not really; 1Gbps also looks like 32MHz * 32 bits wide. You wouldn't be 
able to do much else besides, apart from push the bits out somewhere 
else though :)
