        - incoming queries to the server with TC bit on are replied FORMERR.
+       - interface-automatic replied the wrong source address on localhost
+         queries. Seems to be due to ifnum=0 in recvmsg PKTINFO. Trying
+         to use ifnum=-1 to mean 'no interface, use kernel route'.

        - interface-automatic feature. experimental. Nice for anycast.
