How do I verify the speed of my NIC?

I just installed a new gigabit network interface card (NIC) in Linux. How do I tell if it is really set to gigabit speeds? I see ethtool has an option to set the speed, but I can't seem to figure out how to report its current speed.

How long do managed gigabit ethernet switches take to boot up?

One critical drawback that I have found in researching managed-switches, and one that I have some past experience with is that anything with "lots" of firmware is going to have lots of issues associated with that firmware. We are in the middle of…
