====================
nfp: refactor app init, and minor flower fixes

This series is a part 2 to what went into net as a simpler fix.
In net we simply moved when existing callbacks are invoked to
ensure flower app does not still use representors when lower
netdev has already been destroyed.  In this series we add a
callback to notify apps when vNIC netdevs are fully initialized
and they are about to be destroyed.  This allows flower to spawn
representors at the right time, while keeping the start/stop
callbacks for what they are intended to be used - FW initialization
over control channel.

Patch 4 improves drop monitor interaction and patch 5 changes
the default Kconfig selection of flower offload.  Patch 6 fixes
locking around representor updates which got lost in net-next.
