NFP only supports SWITCHDEV_ATTR_ID_PORT_PARENT_ID, which makes it a
great candidate to be converted to use the ndo_get_port_parent_id() NDO
instead of implementing switchdev_port_attr_get().
Since NFP uses switchdev_port_same_parent_id() convert it to use
netdev_port_same_parent_id().

PCI PFs can host more than one logical endpoint. In NFP terms
this means having more than one vNIC for PCIe PF. The vNICs
are usually corresponding 1:1 to Ethernet ports. In core NIC
we use the legacy idea of vNIC *being* the Ethernet port,
hence netdevs put pX(sY) in their phys_port_name, like Ethernet
ports would. When ASIC ports are fully represented we need to
be able to name different PCIe PF ports, too. Use a scheme
similar to Ethernet ports - pfXsY, for PCIe PF number X,
sub-port Y.

Current control firmware does not cater too well to multi-host
applications. There is no way to check which hosts are up or
otherwise negotiate what the state of the external port (the
Ethernet port) should be. Make sure the link is up when driver
loads, and don't take it down when Ethernet port netdev is
closed.

All netdevs which can accept TC offloads must implement
.ndo_set_features(). nfp_reprs currently do not do that, which
means hw-tc-offload can be turned on and off even when offloads
are active.
Whether the offloads are active is really a question to nfp_ports,
so remove the per-app tc_busy callback indirection thing, and
simply count the number of offloaded items in nfp_port structure.

When a netdev (PF netdev or representor) is opened or closed, set the
physical port config bit appropriately - which powers UP/DOWN the PHY
module for the physical interface.
The PHY is powered first in the HW/FW configuration step when opening
the netdev and again last in the HW/FW configuration step when closing
the netdev.
This is only applicable when there is a physical port associated with
the netdev and if the NSP support this. Otherwise we silently ignore
this step.
The 'nfp_eth_set_configured' can actually return positive values -
updated the function documentation appropriately.
