+ depends on XFRM
+ help
+ 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.
