I'll add the new extra text from the Kconfig help text in the next patch set. Here it is now though:

	  Information on the IP-TFS/AGGFRAG encapsulation can be found
	  in RFC 9347. This feature supports demand driven (i.e.,
	  non-constant send rate) IP-TFS to take advantage of the
	  AGGFRAG ESP payload encapsulation. This payload type
	  supports aggregation and fragmentation of the inner IP
	  packet stream which in turn yields higher small-packet
	  bandwidth as well as reducing MTU/PMTU issues. Congestion
	  control is unimplementated as the send rate is demand driven
	  rather than constant.

Thanks!
Chris.
