[PATCH 1/2] mac_pton: support MAC addresses with other delimiters

[Michael Pratt]

From: Michael Pratt <mcpratt@xxxxx>

Some network hardware vendors may do something unique
when storing the MAC address into hardware in ASCII,
like using hyphens as the delimiter.

Allow parsing of MAC addresses with a non-standard
delimiter (punctuation other than a colon).

e.g. aa-bb-cc-dd-ee-ff
