Sync ether_ioctl() with ioctl(2) and ifnet.if_ioctl

Browse Source 
as to the type of the command argument: int -> u_long.
These types have different widths in the 64-bit world.

Add a note to UPDATING because the change breaks KBI
on 64-bit platforms.

The ether_ioctl() function has been synchronized with ioctl(2)
and ifnet.if_ioctl. Due to that, the size of one of its arguments
has changed on 64-bit architectures. All kernel modules using
ether_ioctl() need to be rebuilt on such architectures.
