Other Match Extensions
The other two extensions in the netfilter package are demonstration
extensions, which (if installed) can be invoked with the `-m' option.
mac
This module must be explicitly specified with `-m mac' or `--match mac'.
It is used for matching incoming packet's source Ethernet (MAC) address, and
thus only useful for packets traversing the INPUT and FORWARD chains. It
provides only one option:
--mac-source
followed by an optional `!', then an ethernet address in colon-separated
hexbyte notation, eg `--mac-source 00:60:08:91:CC:B7'. "
