[PATCH] Whitelist NICs that violate MAC assignement scheme

[PATCH] Whitelist NICs that violate MAC assignement scheme

[Lubomir Rintel]

According to list of assigned ethernet codes [1] referred to by
IANA [2] certain global addresses do not follow the assignement
scheme and use numbers reserved for local use. Several such adapters
are quite widely used, generate rules for them.
