tristate "IPsec IP-TFS/AGGFRAG (RFC 9347) encapsulation support"
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.
