In case we got an FDB notification for a port that doesn't exist we
execute an FDB entry delete to prevent it from re-appearing the next
time we poll for notifications.
If the operation failed we would trigger a NULL pointer dereference as
'mlxsw_sp_port' is NULL.
Fix it by reporting the error using the underlying bus device instead.

In virtual mode, packets are classified to FIDs based on their ingress
port and VLAN whereas in non-virtual mode only the VLAN is taken into
account.
Currently ports are initialized to use virtual mode due to the presence
of the PVID vPort. However, we're going to transition ports between both
modes based on the FIDs they use and not merely based on the presence on
a VLAN upper. Therefore, during initialization, no mode will be
explicitly set.
Since the Programmer's Reference Manual (PRM) doesn't specify a default,
explicitly set the port to non-virtual mode and later transition the
port between both modes based on the FIDs it uses.
In a follow-up patchset, this step will be moved to the common FID core
where it logically belongs.

switchdev's VLAN object has the ability to describe a range of VLAN IDs,
but this is only used when VLAN operations are done using the SELF flag,
which is something we would like to remove as it allows one to bypass
the bridge driver.

preparing it for refactoring in a follow-up patchset.

When a netdev is enslaved to a VRF master, its router interface (RIF)
needs to be destroyed (if exists) and a new one created using the
corresponding virtual router (VR).
>From the driver's perspective, the above is equivalent to an inetaddr
event sent for this netdev. Therefore, when a port netdev (or its
uppers) are enslaved to a VRF master, call the same function that
would've been called had a NETDEV_UP was sent for this netdev in the
inetaddr notification chain.
This patch also fixes a bug when a LAG netdev with an existing RIF is
enslaved to a VRF. Before this patch, each LAG port would drop the
reference on the RIF, but would re-join the same one (in the wrong VR)
soon after. With this patch, the corresponding RIF is first destroyed
and a new one is created using the correct VR.

When there is no FID set for a specific packet, the HW will drop it.
However, by default these packets are useful to be delivered to CPU as
it can inspect them and program HW accordingly. So add this trap.
This would only ever happen when port is enslaved to an OVS master.
Otherwise, packets would be dropped during VLAN / STP filtering,
before FID classification.

So far, mlxsw_sp_port_vlan_set range is limited by
MLXSW_REG_SPVM_REC_MAX_COUNT. In spectrum_switchdev code this is
wrapped up by a helper function which actually does multiple calls
to FW for bigger ranges. Move the code into mlxsw_sp_port_vlan_set
and use it always. That allows caller not to care about the range.
