Subject: [PATCH] firewall (#7355) - partially revert r21486, start firewall on
 init again - skip iface hotplug events if base fw is not up yet - get ifname
 and up state with uci_get_state() in iface setup since the values gathered by
 scan_interfaces() may be outdated when iface coldplugging happens (observed
 with pptp) - ignore up state when bringing down interfaces because ifdown
 reverts state vars before dispatching the iface event - bump package revision
