MAC Address vs MAC controls
There are a few places where the option for MAC address is labeled as MAC controls (interfaces, DHCP static mapping edit, etc.).
Is this intentional? I've never seen it referred to like that before. Seems kind of odd like that.
A MAC (Media Access Control) address is what is being entered into the option field. Not a MAC (Media Access Control) control.
It probably isn't the best naming convention in the world, but it's short for "control of MAC address". I'd be fine with renaming all those "MAC Address" if you want to submit a PR.
