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>.

To reduce the coupling of slow path ring implementations and their
callers, use callbacks instead.
Changes to Jakub's work:
* Also use callbacks for xmit functions

In preparation for support for a new datapath format move all
ring and fast path logic into separate files. It is basically
a verbatim move with some wrapping functions, no new structures
and functions added.
The current data path is called NFD3 from the initial version
of the driver ABI it used. The non-fast path, but ring related
functions are moved to nfp_net_dp.c file.
Changes to Jakub's work:
* Rebase on xsk related code.
* Split the patch, move the callback changes to next commit.
