It was even a decade ago, but the world moved on. virtualization has
supported newer NICs for years.

Ed(4) doesn't do DMA and is quite limited in terms of what it can do.

But even so, we'd set the threshold at 5 or 10 installed machines running
11 or newer. If Julian legit has that many machines, then we can remove it
from the list. In the initial period of this process, all the folks that
were concerned turned put to not have machines. The nycbug dmesg stats also
showed no use after 8 or so.
