net: marvell: prestera: Propagate nh state from hw to kernel
We poll nexthops in HW and call for each active nexthop appropriate
neighbour.
Also we provide implicity neighbour resolving.
For example, user have added nexthop route:
# ip route add 5.5.5.5 via 1.1.1.2
But neighbour 1.1.1.2 doesn't exist. In this case we will try to call
neigh_event_send, even if there is no traffic.
This is useful, when you have add route, which will be used after some
time but with a lot of traffic (burst). So, we has prepared, offloaded
route in advance.

net: prestera: manage matchall and flower priorities
matchall rules can be added only to chain 0 and their priorities have
limitations:
- new matchall ingress rule's priority must be higher (lower value)
than any existing flower rule;
- new matchall egress rule's priority must be lower (higher value)
than any existing flower rule.
The opposite works for flower rule adding:
- new flower ingress rule's priority must be lower (higher value)
than any existing matchall rule;
- new flower egress rule's priority must be higher (lower value)
than any existing matchall rule.
This is a hardware limitation and thus must be properly handled in
driver by reporting errors to the user when newly added rule has such a
priority that cannot be installed into the hardware.
To achieve this, the driver must maintain both min/max matchall
priorities for every flower block when user adds/deletes a matchall
rule, as well as both min/max flower priorities for chain 0 for every
adding/deletion of flower rules for chain 0.
