Currently, the devlink_port structure is stored within the ice_pf. This
made sense because we create a single devlink_port for each PF. This
setup does not mesh with the abstractions in the driver very well, and
led to a flow where we accidentally call devlink_port_unregister twice
during error cleanup.
In particular, if devlink_port_register or devlink_port_unregister are
called twice, this leads to a kernel panic. This appears to occur during
some possible flows while cleaning up from a failure during driver
probe.
If register_netdev fails, then we will call devlink_port_unregister in
ice_cfg_netdev as it cleans up. Later, we again call
devlink_port_unregister since we assume that we must cleanup the port
that is associated with the PF structure.
This occurs because we cleanup the devlink_port for the main PF even
though it was not allocated. We allocated the port within a per-VSI
function for managing the main netdev, but did not release the port when
cleaning up that VSI, the allocation and destruction are not aligned.
Instead of attempting to manage the devlink_port as part of the PF
structure, manage it as part of the PF VSI. Doing this has advantages,
as we can match the de-allocation of the devlink_port with the
unregister_netdev associated with the main PF VSI.
Moving the port to the VSI is preferable as it paves the way for
handling devlink ports allocated for other purposes such as SR-IOV VFs.
Since we're changing up how we allocate the devlink_port, also change
the indexing. Originally, we indexed the port using the PF id number.
This came from an old goal of sharing a devlink for each physical
function. Managing devlink instances across multiple function drivers is
not workable. Instead, lets set the port number to the logical port
number returned by firmware and set the index using the VSI index
(sometimes referred to as VSI handle).

Add devlink reload action to allow the user to request a specific reload
action. The action parameter is optional, if not specified then devlink
driver re-init action is used (backward compatible).
Note that when required to do firmware activation some drivers may need
to reload the driver. On the other hand some drivers may need to reset
the firmware to reinitialize the driver entities. Therefore, the devlink
reload command returns the actions which were actually performed.
Reload actions supported are:
driver_reinit: driver entities re-initialization, applying devlink-param
and devlink-resource values.
fw_activate: firmware activate.
command examples:
$devlink dev reload pci/0000:82:00.0 action driver_reinit
reload_actions_performed:
driver_reinit
$devlink dev reload pci/0000:82:00.0 action fw_activate

When adding support for version 3 of the GEO_TX_POWER_LIMIT command,
the table argument of iwl_sar_geo_init was changed from a pointer a 1d
array of now-removed iwl_per_chain_offset_group_v1 to a pointer to a 2d
array of iwl_per_chain_offset (iwl_per_chain_offset_group_v1 was a
struct containing 2 copies of iwl_per_chain_offset).
So even for version 2 where the second dimension is of length 2, which
means that the underlying memory layout of the array didn't change, this
requires a small change in the way we loop over it, and this was missed.
Additionally, for the case of version 3 where the second dimension is now
3, in order to fill the first two elements of each row correctly (lb and
hb), iwl_sar_geo_init must get the true number of bands supported.
But because we don't yet store any values for the 3rd (uhb) band, skip
that band.
