True. My point is that the speed of a particular card is pretty useless
by itself. It really depends on what the rest of the network does. Jumbo
frame speed is irrelevant if the rest of the network doesn't support it.
Gigabit is not relevant if everything else on the network is 10/100.
If you know that your LAN is Gigabit and supports jumbo frames, then that
is a good decision.
