- weaken logging priority for /etc/resolv.conf open failure
- gather stats, emit stats by SIGUSR1
- use SIOCGIFMTU to get interface MTU (just a matter of #ifdef)

+#   Mainly IPv6 prefixes are configured in this part. However, rtadvd
+#   automatically learns appropriate prefixes from the kernel's routing
+#   table and advertises the prefixes, so you don't have to configure
+#   this part, either.
+#   If you don't want the automatic advertisement, invoke rtadvd with
+#   the -s option and configure this part by hand.
