I think that cmdline.txt should be described in plan9.ini(8)

The performance of the usb/ether driver without etherusb is much,
much worse. I think is a good idea to move it to port. Those devices
are very common nowadays, and can save your day if your ethernet
card breaks, or if your new computer has incompatible drivers, etc.

What I would love to see is the kernel creating the '#l' device
when a usb ethernet card is attached, and destroy it when the card
is unplugged. But that's the dream of an ignorant, that would already
been done if it were feasible, I suppose.
