a83d958504 Bluetooth: Fix VIRTIO_ID_BT assigned number
It turned out that the VIRTIO_ID_* are not assigned in the virtio_ids.h
file in the upstream kernel. Picking the next free one was wrong and
there is a process that has been followed now.

See https://github.com/oasis-tcs/virtio-spec/issues/108 for details.

f8e0a68bab net/smc: avoid possible duplicate dmb unregistration
smc_lgr_cleanup() calls smcd_unregister_all_dmbs() as part of the link
group termination process. This is a leftover from the times when
smc_lgr_cleanup() scheduled a worker to actually free the link group.
Nowadays smc_lgr_cleanup() directly calls smc_lgr_free() without any
delay so an earlier dmb unregistration is no longer needed.
So remove smcd_unregister_all_dmbs() and the call to it.

c356be0574 Merge branch 'xpcs-phylink_pcs_ops'
Vladimir Oltean says:

====================
Convert xpcs to phylink_pcs_ops

Background: the sja1105 DSA driver currently drives a Designware XPCS
for SGMII and 2500base-X, and it would be nice to reuse some code with
the xpcs module. This would also help consolidate the phylink_pcs_ops,
since the only other dedicated PCS driver, currently, is the lynx_pcs.

Therefore, this series makes the xpcs expose the same kind of API that
the lynx_pcs module does. The main changes are getting rid of struct
mdio_xpcs_ops, being compatible with struct phylink_pcs_ops and being
less reliant on the phy_interface_t passed to xpcs_probe (now renamed to
xpcs_create).

This patch series is partially tested (some code paths have been covered
on the NXP SJA1105 and some others with the help of Vee Khee Wong on
Intel Tiger Lake / stmmac) but further testing on 10G setups would be
appreciated, if possible.

11059740e6 net: pcs: xpcs: convert to phylink_pcs_ops
Since all the remaining members of struct mdio_xpcs_ops have direct
equivalents in struct phylink_pcs_ops, it is about time we remove it
altogether.

Since the phylink ops return void, we need to remove the error
propagation from the various xpcs methods and simply print an error
message where appropriate.

Since xpcs_get_state_c73() detects link faults and attempts to reset the
link on its own by calling xpcs_config(), but xpcs_config() now has a
lot of phylink arguments which are not needed and cannot be simply
fabricated by anybody else except phylink, the actual implementation has
been moved into a smaller xpcs_do_config().

The const struct mdio_xpcs_ops *priv->hw->xpcs has been removed, so we
need to look at the struct mdio_xpcs_args pointer now as an indication
whether the port has an XPCS or not.

2cac15dae2 net: pcs: xpcs: convert to mdio_device
Unify the 2 existing PCS drivers (lynx and xpcs) by doing a similar
thing on probe, which is to have a *_create function that takes a
struct mdio_device * given by the caller, and builds a private PCS
structure around that.

This changes stmmac to hold only a pointer to the xpcs, as opposed to
the full structure. This will be used in the next patch when struct
mdio_xpcs_ops is removed. Currently a pointer to struct mdio_xpcs_ops
is used as a shorthand to determine whether the port has an XPCS or not.
We can do the same now with the mdio_xpcs_args pointer.

9900074ecc net: pcs: xpcs: make the checks related to the PHY interface mode stateless
The operating mode of the driver is currently to populate its
struct mdio_xpcs_args::supported and struct mdio_xpcs_args::an_mode
statically in xpcs_probe(), based on the passed phy_interface_t,
and work with those.

However this is not the operation that phylink expects from a PCS
driver, because the port might be attached to an SFP cage that triggers
changes of the phy_interface_t dynamically as one SFP module is
unpluggged and another is plugged.

To migrate towards that model, the struct mdio_xpcs_args should not
cache anything related to the phy_interface_t, but just look up the
statically defined, const struct xpcs_compat structure corresponding to
the detected PCS OUI/model number.

So we delete the "supported" and "an_mode" members of struct
mdio_xpcs_args, and add the "id" structure there (since the ID is not
expected to change at runtime).

Since xpcs->supported is used deep in the code in _xpcs_config_aneg_c73(),
we need to modify some function headers to pass the xpcs_compat from all
callers. In turn, the xpcs_compat is always supplied externally to the
xpcs module:
- Most of the time by phylink
- In xpcs_probe() it is needed because xpcs_soft_reset() writes to
  MDIO_MMD_PCS or to MDIO_MMD_VEND2 depending on whether an_mode is clause
  37 or clause 73. In order to not introduce functional changes related
  to when the soft reset is issued, we continue to require the initial
  phy_interface_t argument to be passed to xpcs_probe() so we can pass
  this on to xpcs_soft_reset().
- stmmac_open() wants to know whether to call stmmac_init_phy() or not,
  and for that it looks inside xpcs->an_mode, because the clause 73
  (backplane) AN modes supposedly do not have a PHY. Because we moved
  an_mode outside of struct mdio_xpcs_args, this is now no longer
  directly possible, so we introduce a helper function xpcs_get_an_mode()
  which protects the data encapsulation of the xpcs module and requires
  a phy_interface_t to be passed as argument. This function can look up
  the appropriate compat based on the phy_interface_t.

a54a8b71f6 net: pcs: xpcs: there is only one PHY ID
The xpcs driver has an apparently inadequate structure for the actual
hardware it drives.

These defines and the xpcs_probe() function would suggest that there is
one PHY ID per supported PHY interface type, and the driver simply
validates whether the mode it should operate in (the argument of
xpcs_probe) matches what the hardware is capable of:

	#define SYNOPSYS_XPCS_USXGMII_ID	0x7996ced0
	#define SYNOPSYS_XPCS_10GKR_ID		0x7996ced0
	#define SYNOPSYS_XPCS_XLGMII_ID		0x7996ced0
	#define SYNOPSYS_XPCS_SGMII_ID		0x7996ced0
	#define SYNOPSYS_XPCS_MASK		0xffffffff

but that is not the case, because upon closer inspection, all the above
4 PHY ID definitions are in fact equal.

So it is the same XPCS that is compatible with all 4 sets of PHY
interface types.

This change introduces an array of struct xpcs_compat which is populated
by the single struct xpcs_id instance. It also eliminates the bogus
defines for multiple Synopsys XPCS PHY IDs and replaces them with a
single XPCS_ID, which better reflects the way in which the hardware
operates.

Because we are touching this area of the code anyway, the new array of
struct xpcs_compat, as well as the array of xpcs_id, have been moved
towards the end of the file, since they are variable declarations not
definitions. If whichever of struct xpcs_compat or struct xpcs_id need
to gain a function pointer member in the future, it is easier to
reference functions (no forward declarations needed) if we have the
const variable declarations at the end of the file.

Commit c7a219048e ("ice: Remove xsk_buff_pool from VSI structure")
silently introduced a regression and broke the Tx side of AF_XDP in copy
mode. xsk_pool on ice_ring is set only based on the existence of the XDP
prog on the VSI which in turn picks ice_clean_tx_irq_zc to be executed.
That is not something that should happen for copy mode as it should use
the regular data path ice_clean_tx_irq.

This results in a following splat when xdpsock is run in txonly or l2fwd
scenarios in copy mode:

Fix this by introducing the bitmap of queues that are zero-copy enabled,
where each bit, corresponding to a queue id that xsk pool is being
configured on, will be set/cleared within ice_xsk_pool_{en,dis}able and
checked within ice_xsk_pool(). The latter is a function used for
deciding which napi poll routine is executed.
Idea is being taken from our other drivers such as i40e and ixgbe.

5379260852 igb: Fix XDP with PTP enabled
When using native XDP with the igb driver, the XDP frame data doesn't point to
the beginning of the packet. It's off by 16 bytes. Everything works as expected
with XDP skb mode.

Actually these 16 bytes are used to store the packet timestamps. Therefore, pull
the timestamp before executing any XDP operations and adjust all other code
accordingly. The igc driver does it like that as well.

Tested with Intel i210 card and AF_XDP sockets.

Driver can be used in different environments and moreover, when compiled
with !OF, the compiler may issue a warning due to unused mrf24j40_of_match
variable. Hence drop unneeded of_match_ptr() call.

While at it, update headers block to reflect above changes.

ad6f5cc5f6 net/ieee802154: drop unneeded assignment in llsec_iter_devkeys()
In order to keep the code style consistency of the whole file,
redundant return value ‘rc’ and its assignments should be deleted

The clang_analyzer complains as follows:
net/ieee802154/nl-mac.c:1203:12: warning: Although the value stored to
'rc' is used in the enclosing expression, the value is never actually
read from 'rc'

No functional change, only more efficient.
