[uml-devel] [PATCH 16/20] UML - Use of a public MAC is a warning, not an error

[Jeff Dike <jdike@addtoit.com>]

Downgrade one of the MAC validity checks.  If it's one that could be
possibly assigned to a physical NIC, then nothing will break.  So,
emit a warning in this case, but keep the requested MAC.
