and fix assigning IP addresses to the gif(4) interface when it is a
member of a if_bridge(4) interface.
When setting the sysctl net.link.bridge.member_ifaddrs to 1, if_bridge(4)
can eliminate unnecessary walk of the member list to determine whether
the inbound unicast packets are for us or not.
Well when a gif(4) interface is member of a if_bridge(4) interface, it
acts as the tunnel endpoint to tunnel Ethernet frames over IP network,
aka the EtherIP protocol, so the IP addresses configured on it are
independent of the if_bridge(4) interface or other if_bridge(4) members,
hence the sysctl net.link.bridge.member_ifaddrs should not have any
influnce over gif(4) interfaces's behavior of assigning IP addresses.
