Document how to change MAC addresses

This article points out how to change MAC addresses on all major platforms. It's a common procedure, specifically in the WiFi world, and thus needs get incorporated into the hacksheet.

iproute version:

ip link set eth0 down
ip link set eth0 address 00:01:02:03:04:05

I don't believe this part: "Normally you have to bring the interface down before the change."

When I was doing a lot of WiFi stuff in the past (5+ years ago), at least on Linux, it was necessary to bring down the interface for the change to be effective. Maybe that has changed since?!
