>Description:
For user specified firewall types (rc.conf $firewall_type), rc.firewall
simply calls ipfw with $firewall_type as the only argument.  It
would be nice if there was a mechanism to pass additional flags
to ipfw, such as "-p /usr/bin/cpp".

Attached is a small patch to allows, but does not require,
$firewall_flags to set in rc.conf and for these flags to be
passed to ipfw when a user has specified an alternative
firewall type.

It is meant to be used as follows:
firewall_enable="YES"
firewall_script="/etc/rc.firewall"
firewall_type="/etc/firewall.ipfw"
firewall_quiet="YES"
firewall_flags="-p /usr/bin/cpp -D router"
