[package] firewall:
- solve scoping issues when multiple values are used, thanks Daniel Dickinson - ignore src_port/dest_port for proto icmp rules, ignore icmp_type for non-icmp rules - properly handle icmp when proto is given in numerical form (1, 58) - support negated icmp types git-svn-id: svn://svn.openwrt.org/openwrt/trunk@27500 3c298f89-4303-0410-b956-a3cf2f4a3e73
