Make net.link.ether.ipfw read-write so users of ipfw2 can
set it to 1 to try MAC filtering of layer2 packets.

It also works with ipfw, but 1) you are not supposed to know,
and 2) ipfw does not have instructions to match MAC fields.

See the commit log for rev.1.111 of this file to understand
when the firewall is invoked. We do not have separate firewall
chains yet so if you are not careful the same packet can be
processed by ipfw up to 4 times.
