	src/sys/lkm/net/ethfoo/ethfoo: Makefile ethfoo_lkm.c
Added Files:
	src/sys/lkm/net/ethfoo/ethfoo: ethfoo.h

Log Message:
Turn ethfoo(4) into a cloning device, following the MOVEFD semantics (like
bpf(4)).

While doing that, still keep around the full cdevsw interface, so that the
ethfoo interfaces can be accessed either through /dev/ethfooN or through
the cloning device /dev/ethfoo (whose minor number is 0xfffff).  Interfaces
created through the cloning device are destroyed at close() time.

Also add an ioctl() to be used by the cloning interface user to know the
minor number of the created interface, so it can be manipulated later to
get an address set and turned up (otherwise EHOSTDOWN is returned on read
and write).

Document some of the new functions, but read, write, ioctl and kqfilter
still has to be commented.
