4) Previously, if the 'optional' option was given to an interface with
a wildcard physical name, specific instances of the interface were
never considered usable.
Example:
/etc/shorewall/interfaces:
#ZONE INTERFACE BROADCAST OPTIONS
net ppp+ - optional
/etc/shorewall/providers:
#PROVIDER NUMBER MARK DUPLICATE INTERFACE ...
XYZTEL 1 - main ppp0
The XYZTEL provider was never usable.
This configuration now generates a compile-time error.
