Subject: [ETHER 07/18]: Bring back MAC_FMT

[ETHER]: Bring back MAC_FMT

The print_mac function is not very suitable for debugging printks
in performance critical paths since without ifdefs it will always
get called. MAC_FMT can be used with pr_debug without any overhead
when debugging is disabled.
