[BusyBox] [PATCH] macadddr command

[Jason Schoon]

It's been quite a while since I included ifconfig in my system, but it
seems to me that it was quite a pig.  I could see wanting this small
utility instead, if ifconfig was not being used for other tasks.

We have a small utilty named ifethmac that does nothing more than set
the MAC address of an interface.  Perhaps I should marry that with
this mac-addr code to create an ifethmacgetset type of thing.

Just my thoughts...
