+Subject: [PATCH] kernel_netlink: Convert src_plen to v4mapped encoding on
+ import
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+src_plen for IPv4 routes imported from kernel has not been adjusted
+to v4mapped encoding. Therefore IPv4 xroutes used an inconsistent encoding
+which lead to failed comparisons when sending updates.
+
+Routes received from neighbors with the same prefix as xroutes therefore
+have been announced to neighbours instead.
+
+This issue is fixed by converting src_plen on import.
+
