Upon receiving the now encrypted packet it is passed to the next layer either by sending it to the Linux stack for routing or doing a direct tail call if an overlay is in use. 6 (on/off/module) IPsec user configuration interface depends on INET && XFRM Support for IPsec user configuration The Linux Kernel documentation ¶ This is the top level of the kernel’s documentation tree. For the Linux operating system, there are two choices for an IPsec implementation, the default builtin NETKEY (aka XFRM) IPsec stack, or the libreswan native KLIPS IPsec stack. The name XFRM stands for "transform" referencing the transformation of IP packets as per the IPSec protocol.

This is a complete redesign of the architecture, that makes use of the xfrm framework. After successful IKE negotiation the ipsec service (charon in the strongSwan project) installs a policy that tells the kernel to use encryption if the packet matches the security association (SA). ip xfrm policy set configure the policy hash table Security policies whose address prefix lengths are greater than or equal policy hash table thresholds are hashed. The purpose of these interfaces is to overcome the design limitations that the existing VTI devices have. The driver exports debug information such as internal statistics, debug information, MAC and DMA registers etc. Help dialogs for these items do not list module names; suggests to me devs preferred builtin; fact that they can be modules suggests modules are okay.
