+Subject: [PATCH 09/10] Do unsolicited RAs for interfaces which appear after
+ dnsmasq startup.
+
+I noticed that dnsmasq often wasn't sending any unsolicited RAs for me.
+
+This turned out to happen when the interface (a bridge interface) wasn't
+created yet at the time dnsmasq started. When dnsmasq is started after
+the interface is created, it sends RAs as expected. I assume this also
+extends to other types of virtual interfaces that are created after
+dnsmasq starts.
+
+Digging into the source, it seems to be caused by a missing call to
+ra_start_unsolicited for non-template contexts in construct_worker from
+src/dhcp6.c. The attached patch adds that call, but only if the
+interface index or address changed to prevent doing fast RAs for no reason.
+
+I tested it on my own server and it appears to work as expected. When
+the interface is created and configured, dnsmasq does fast RAs for a
+while and then settles into slow RAs.
