The ipvlan code already knows how to detect when a duplicate address is
about to be assigned to an ipvlan device. However, that failure is not
propogated outward and leads to a silent failure.
Introduce a validation step at ip address creation time and allow device
drivers to register to validate the incoming ip addresses. The ipvlan
code is the first consumer. If it detects an address in use, we can
return an error to the user before beginning to commit the new ifa in
the networking code.
This can be especially useful if it is necessary to provision many
ipvlans in containers. The provisioning software (or operator) can use
this to detect situations where an ip address is unexpectedly in use.

because devices may potentially learn FDB that are not directly related

1. Mixed SW/HW bridge - FDBs that point to the ASICs external devices
should be offloaded as CPU traps in order to
perform forwarding in slow path.
2. EVPN - Externally learned FDBs for the vtep device.

We add driver support for offload these partial re-writes, by setting

The 1st bit set in the mask specifies both the offset and the right

NFD ABI 0.5 is equivalent to NFD ABI 3.0 but requires that the
driver checks the APP id symbol and makes sure it can support
given app. Most advanced apps will likely require control vNIC
(ability to exchange control messages between the driver and
app FW). Detailed app version checking and capability exchange
is left to app-specific code.

When driver encounters an nfp_app which has a control message handler
defined, allocate a control vNIC. This control channel will be used
to exchange data with the application FW such as flow table programming,
statistics and global datapath control.

Thus far the code assumed all vNICs will request similar number of IRQs.
This will be no longer true with control vNICs (where 1 IRQ will suffice).

We want to be able to create a special vNIC for control messages.
This vNIC should be created before any netdev is registered to allow
nfp_app logic to exchange messages with the FW app before any netdev
is visible to user space. Unfortunately we can't enable IRQs until
we know how many vNICs we will need to spawn.
Divide the function which spawns netdevs for vNICs into three parts:
- vNIC/memory allocation;
- IRQ allocation;
- netdev init and register.
This will help us insert the initialization of the control channel
after IRQ allocation but before netdev init and register.

Reading fw version from the BAR is trivial. Don't pass it around
through layers of init functions, simply read it again where needed.
This commit has the side effect of each vNIC having the exact NFD
version from its own control memory, rather than all data vNICs
assuming the version of the first one. This should not result in
user-visible changes, though. Capabilities of data vNICs of trival
apps are identical.

Our open/close implementations have 3 stages:
- allocation/freeing of ring resources, irqs etc.,
- device config,
- device/stack enable (can't fail).
Right now all of those stages are placed in separate functions,
apart from allocation during open. Fix that. It will make it
easier for us to allocate resources for netdev-less vNICs.
Because we want to reuse allocation code in netdev-less vNICs
leave the netif_set_real_num_[rt]x_queues() calls inside open.

Add phylib support for the Marvell Alaska X 10 Gigabit PHY (MV88X3310).
This phy is able to operate at 10G, 1G, 100M and 10M speeds, and only
supports Clause 45 accesses.
The PHY appears (based on the vendor IDs) to be two different vendors
IP, with each devad containing several instances.
This PHY driver has only been tested with the RJ45 copper port, fiber
port and a Marvell Armada 8040-based ethernet interface.
It should be noted that to use the full range of speeds, MAC drivers
need to also reconfigure the link mode as per phydev->interface, since
the PHY automatically changes its interface mode depending on the
negotiated speed.
