	  A feature to update locator(s) of a given IPsec security

	  where mobile nodes change their attachment point to the Internet.

	  If unsure, say N.

	  This statistics is not a SNMP/MIB specification but shows

	  Add a PF_KEY MIGRATE message to PF_KEYv2 socket family.
	  The PF_KEY MIGRATE message is used to dynamically update
	  locator(s) of a given IPsec security association.
	  This feature is required, for instance, in a Mobile IPv6
	  environment with IPsec configuration where mobile nodes
