While debugging a recent failure to update the flash of an ice device,
I found it helpful to add additional logging which helped determine the
root cause of the problem being a timeout issue.

Add some extra dev_dbg() logging messages which can be enabled using the
dynamic debug facility, including one for ice_aq_wait_for_event that
will use jiffies to capture a rough estimate of how long we waited for
the completion of a firmware command.

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).

Moshe Shemesh says:

====================
Add devlink reload action and limit options

Introduce new options on devlink reload API to enable the user to select
the reload action required and constrains limits on these actions that he
may want to ensure. Complete support for reload actions in mlx5.
The following reload actions are supported:
  driver_reinit: driver entities re-initialization, applying devlink-param
                 and devlink-resource values.
  fw_activate: firmware activate.

The uAPI is backward compatible, if the reload action option is omitted
from the reload command, the driver reinit action will be used.
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.

By default reload actions are not limited and driver implementation may
include reset or downtime as needed to perform the actions.
However, if reload limit is selected, the driver should perform only if
it can do it while keeping the limit constraints.
Reload limit added:
  no_reset: No reset allowed, no down time allowed, no link flap and no
            configuration is lost.

Each driver which supports devlink reload command should expose the
reload actions and limits supported.

Add reload stats to hold the history per reload action per limit.
For example, the number of times fw_activate has been done on this
device since the driver module was added or if the firmware activation
was done with or without reset.

Patch 1 changes devlink_reload_supported() param type to enable using
        it before allocating devlink.
Patch 2-3 add the new API reload action and reload limit options to
          devlink reload.
Patch 4-5 add reload stats and remote reload stats. These stats are
          exposed through devlink dev get.
Patches 6-11 add support on mlx5 for devlink reload action fw_activate
            and handle the firmware reset events.
Patches 12-13 add devlink enable remote dev reset parameter and use it
             in mlx5.
Patches 14-15 mlx5 add devlink reload limit no_reset support for
              fw_activate reload action.

reached yet the received, either the worker or recvmsg()
can find a subflow with the data_avail flag set - since
the current mapping is valid and in sequence - but no
skbs in the receive queue - since the other entity just
processed them.

The above will lead to an unbounded loop in __mptcp_move_skbs()

This change addresses the issue stopping the __mptcp_move_skbs()

   - last minute fix / improvement of a MRP netlink (uAPI) interface
     introduced in 5.9 (current) release

   - fix "unresolved symbol" build error under CONFIG_NET w/o
     CONFIG_INET due to missing tcp_timewait_sock and inet_timewait_sock
     BTF.

   - fix 32 bit sub-register bounds tracking in the bpf verifier for OR
     case

   - tcp: fix receive window update in tcp_add_backlog()

   - openvswitch: handle DNAT tuple collision in conntrack-related code

   - r8169: wait for potential PHY reset to finish after applying a FW
     file, avoiding unexpected PHY behaviour and failures later on

   - mscc: fix tail dropping watermarks for Ocelot switches

   - avoid use-after-free in macsec code after a call to the GRO layer

   - avoid use-after-free in sctp error paths

   - add a device id for Cellient MPL200 WWAN card

   - rxrpc fixes:
      - fix the xdr encoding of the contents read from an rxrpc key
      - fix a BUG() for a unsupported encoding type.
      - fix missing _bh lock annotations.
      - fix acceptance handling for an incoming call where the incoming
        call is encrypted.
      - the server token keyring isn't network namespaced - it belongs
        to the server, so there's no need. Namespacing it means that
        request_key() fails to find it.
      - fix a leak of the server keyring"

Remove propmt for selecting MLX5_VDPA by the user and modify
MLX5_VDPA_NET to select MLX5_VDPA. Also modify MLX5_VDPA_NET to depend
on mlx5_core.

This fixes an issue where configuration sets 'y' for MLX5_VDPA_NET while
MLX5_CORE is compiled as a module causing link errors.

A VM with mlx5 vDPA has below warnings while being reset:

vhost VQ 0 ring restore failed: -1: Resource temporarily unavailable (11)
vhost VQ 1 ring restore failed: -1: Resource temporarily unavailable (11)

We should allow userspace emulating the virtio device be
able to get to vq's avail_index, regardless of vDPA device
status. Save the index that was last seen when virtq was
stopped, so that userspace doesn't complain.

De-referencing skb after call to gro_cells_receive() is not allowed.
We need to fetch skb->len earlier.
