====================
nfp: more set actions and notifier refactor

This series brings updates to flower offload code.  First Pieter adds
support for setting TTL, ToS, Flow Label and Hop Limit fields in IPv4
and IPv6 headers.

Remaining 5 patches deal with factoring out netdev notifiers from flower
code.  We already have two instances, and more is coming, so it's time
to move to one central notifier which then feeds individual feature
handlers.

I start that part by cleaning up the existing notifiers.  Next a central
notifier is added, and used by flower offloads.
