+          SEG6 is an special target for IPv6 Segment Routing encapsualted
+          packets. It supports a set of Segment Routing specific actions
+          that are based on SRH information. It is useful for SRv6 Service
+          Function chaining use-cases.
+
+          To compile it as a module, choose M here.  If unsure, say N.
