Summary
VPP add IPsec netlink XFRM settings. Add configuration mode.
Use case
The purpose of introducing Linux XFRM netlink support in the linux_nl_plugin
is to mirror Linux XFRM configurations to the VPP IPsec subsystem. These
configurations can be manually set using ip commands or via keying daemons
like StrongSwan. In both cases, the netlink notifications generated from
Linux are read by this XFRM module and translated into VPP's IPsec configuration.
