Currently, when port netdevs (or their uppers) are enslaved to a bridge,
we simply propagate the CHANGEUPPER event all the way down and lose the
context of the actual netdevice used as the bridge port.

This leads to a lot of information hanging off the ports (and vPorts),
which doesn't logically belong there, such as mrouter indication and
unknown unicast flood state.

Following patches are going to put the mlxsw_sp_port struct on diet and
instead introduce a bridge port struct, where the above mentioned
information belongs. But in order to do that, we need to be able to
determine the bridge port netdevice, so propagate it down.

We're going to get rid of vPorts completely later in the patchset, but
the router code is self-contained, so it's a good candidate to start the
transition with.

Convert all the functions that expects to operate on a vPort to operate

When a vPort is destroyed, it leaves the FID it's currently mapped to
(if any) and drops the reference. The FID's leave function expects to
get the vPort as its argument, but this will have to change when the
vPort model is retired.

Change the function signature to expect a Port-VLAN struct instead and
patch the call sites accordingly.

The code introduced in this patch will be removed later in the patchset,
but this intermediary step is required in order to ease the code review.

This is the first step in the transition from the vPort model to a
unified Port-VLAN structure. The new structure is defined and created /
destroyed upon invocation of the 8021q ndos, but it's not actually used
throughout the code.

Subsequent patches will initialize it correctly and also create /
destroy it upon switchdev's VLAN object.

We currently transition the port to "Virtual mode" upon the creation of
its first VLAN upper, as we need to classify incoming packets to a FID
using {Port, VID} and not only the VID.

However, it's more appropriate to transition the port to this mode when
the {Port, VID} are actually mapped to a FID. Either during the
enslavement of the VLAN upper to a VLAN-unaware bridge or the
configuration of a router port.

Do this change now in preparation for the introduction of the FID core,
where this operation will be encapsulated.

To prevent regressions, this patch also explicitly configures an OVS
slave to "Virtual mode". Otherwise, a packet that didn't hit an ACL rule
could be classified to an existing FID based on a global VID-to-FID
mapping, thus not incurring a FID mis-classification, which would
otherwise trap the packet to the CPU to be processed by the OVS daemon.

There's a rare pci_driver.probe failure of the VF driver that's caused by
PF/VF handshake going out of sync.  The culprit is octeon_mbox_write() who
ignores an ack timeout condition; it just keeps unconditionally writing all

The mlxfw module is in charge of common logic needed to flash Mellanox
devices firmware, which consists of:
 - Parse the Mellanox Firmware Archive version 2 (MFA2) format, which is
   the format used to store the Mellanox firmware. The MFA2 format file can
   hold firmware for many different silicon variants, differentiated by a
   unique ID called PSID. In addition, the MFA2 file data section is
   compressed using xz compression to save both file-system space and
   memory at extraction time.
 - Implement the firmware flash state machine logic, which is a common
   logic for Mellanox products needed to flash the firmware to the device.

As the module is shared between different Mellanox products, it defines a
set of callbacks to be implemented by the specific driver for hardware
interaction.

Moreover the struct link member speed and port are hard to guess their

So this patch replace speed/port by simpler

directly without using the struct link. This patch convert also their
