+Subject: [PATCH] Fix IPv6-only connectivity
+
+Commit a5dd38ec8 ("Assign Address-IP6 field to netmask instead of address")
+broke IPv6-only configurations, because we only check for ip_info.addr
+and ip_info.addr6 being NULL. We need to allow the connection to continue
+when ip_info.netmask6 is non-NULL too.
