+BREAKING: man:ifconfig[8] will no longer accept misconfigured man:bridge[4]s.
+The Internet Protocol requires IP addresses to be assigned to the bridge, not the underlying member interfaces.
+To temporarily bypass this safeguard, use the net.link.bridge.member_ifaddrs man:sysctl[8]. This sysctl is expected to be removed in FreeBSD 16.

 ARP (man:arp[4]) support for 802-standard networks has been restored; it had been accidentally removed with FDDI support.
 (This is different than the Ethernet standard encapsulation.)
