Subject: [PATCH v1 0/2] mac_pton: support more MAC address formats

Currently, mac_pton() strictly requires the standard ASCII MAC address format
with colons as the delimiter, however,
some hardware vendors don't store the address like that.

If there is no delimiter, one could use strtoul()
but that would leave out important checks to make sure
that each character in the string is hexadecimal.

This series adds support for other delimiters
and lack of any delimiter to the mac_pton() function.

Tested with Openwrt on a MIPS system (ar9344).
