Merge branch 'nfp-update-to-control-structures'

Jakub Kicinski says:

====================
nfp: update to control structures

This series prepares NFP control structures for crypto offloads.
So far we mostly dealt with configuration requests under rtnl lock.
This will no longer be the case with crypto.  Additionally we will
try to reuse the BPF control message format, so we move common code
out of BPF.
