nfp: add framework to support ipsec offloading
A new metadata type and config structure are introduced to
interact with firmware to support ipsec offloading. This
feature relies on specific firmware that supports ipsec
encrypt/decrypt by advertising related capability bit.
The xfrm callbacks which interact with upper layer are
implemented in the following patch.
Based on initial work of Norm Bagley <norman.bagley@netronome.com>.
