+Subject: [PATCH] Linux: Improve learning IPv6 address flags
+
+Rather than matching addresses during netlink message processing,
+extract the local, address and flag parts.
+Once done, then match local and address to the address we are
+looking for and if equal apply the flags.
+
+Fixes #201 and maybe #149.
