+- check_ircd: Remove the perl-IO-Socket-INET6 dependency.
+  * Remove the dependency on perl(IO::Socket::INET6) as it has been
+    deprecated by upstream, is no longer suitable for use and its not
+    being maintained. A compatible replacement for this package is
+    perl(IO::Socket::IP) which is shipped by the perl-base package.
+  * Add monitoring-plugins-ircd-INET6-deprecation.patch
