Add IP-TFS mode to xfrm
|
expand
|
From: Christian Hopps <chopps@labn.net> This patchset adds a new xfrm mode implementing on-demand IP-TFS. IP-TFS (AggFrag encapsulation) has been standardized in RFC9347. Link: https://www.rfc-editor.org/rfc/rfc9347.txt 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. In order to allow loading this fucntionality as a module a set of callbacks xfrm_mode_cbs has been added to xfrm as well.
