Change lynx_pcs_create() to return an error-pointer on failure to
allocate memory, rather than returning NULL. This allows the removal
of the conversion in lynx_pcs_create_fwnode() and
lynx_pcs_create_mdiodev().

We no longer need to export lynx_pcs_create() for drivers to use as we

MIPS Boston board, which is using MIPS_GENERIC kernel is using

Dependency of PCH_GBE, PTP_1588_CLOCK_PCH is also fixed for

Note that CONFIG_PCH_GBE is selected in arch/mips/configs/generic/
board-boston.config for a while, some how it's never wired up

As per the new udp tunnel framework, drivers which need to know the
details of a port entry (i.e. port type) when it gets deleted should
use the .set_port / .unset_port callbacks.
Implementing the current .udp_tunnel_sync callback would mean that the
deleted tunnel port entry would be all zeros. This used to work on
older firmware because it would not check the input when deleting a
tunnel port. With newer firmware, the delete will now fail and
subsequent tunnel port allocation will fail as a result.

The firmware can send PHC_RTC_UPDATE async event on a PF that may not
have PTP registered. In such a case, there will be a null pointer
deference for bp->ptp_cfg when we try to handle the event.
Fix it by not registering for this event with the firmware if !bp->ptp_cfg.
Also, check that bp->ptp_cfg is valid before proceeding when we receive
the event.

We need to call bnxt_hwrm_func_qcfg() on a VF to query the default
VLAN that may be setup by the PF. If a default VLAN is enabled,
the VF cannot support VLAN acceleration on the receive side and
the VNIC must be setup to strip out the default VLAN tag. If a
default VLAN is not enabled, the VF can support VLAN acceleration
on the receive side. The VNIC should be set up to strip or not
strip the VLAN based on the RX VLAN acceleration setting.
Without this call to determine the default VLAN before calling
bnxt_setup_vnic(), the VNIC may not be set up correctly. For
example, bnxt_setup_vnic() may set up to strip the VLAN tag based
on stale default VLAN information. If RX VLAN acceleration is
not enabled, the VLAN tag will be incorrectly stripped and the
RX data path will not work correctly.

Only older NIC controller's firmware uses the PROC AP reset type.
Firmware on 5731X/5741X and newer chips does not support this reset
type. When bnxt_reset() issues a series of resets, this PROC AP
reset may actually fail on these newer chips because the firmware
is not ready to accept this unsupported command yet. Avoid this
unnecessary error by skipping this reset type on chips that don't
support it.

txgbe_shutdown() relies on txgbe_dev_shutdown() to initialise
wake by passing it by reference. However, txgbe_dev_shutdown()
doesn't use this parameter at all.
wake is then passed uninitialised by txgbe_dev_shutdown()
to pci_wake_from_d3().
Resolve this problem by:
* Removing the unused parameter from txgbe_dev_shutdown()
* Removing the uninitialised variable wake from txgbe_dev_shutdown()
* Passing false to pci_wake_from_d3() - this assumes that
although uninitialised wake was in practice false (0).
I'm not sure that this counts as a bug, as I'm not sure that
it manifests in any unwanted behaviour. But in any case, the issue
was introduced by:
3ce7547e5b71 ("net: txgbe: Add build support for txgbe")
Flagged by Smatch as:

The current ice driver's GNSS write implementation buffers writes and
works through them asynchronously in a kthread. That's bad because:
- The GNSS write_raw operation is supposed to be synchronous[1][2].
- There is no upper bound on the number of pending writes.
Userspace can submit writes much faster than the driver can process,
consuming unlimited amounts of kernel memory.
A patch that's currently on review[3] ("[v3,net] ice: Write all GNSS
buffers instead of first one") would add one more problem:
- The possibility of waiting for a very long time to flush the write
work when doing rmmod, softlockups.
To fix these issues, simplify the implementation: Drop the buffering,
the write_work, and make the writes synchronous.
I tested this with gpsd and ubxtool.

In some cases, the PHY can use an external clock source instead of a
crystal.
Add an optional clock in the phy node to make sure that the clock source
is enabled, if specified, before probing.

Commit 699b045a8e43 ("net: virtio_net: notifications coalescing
support") added coalescing command support for virtio_net. However,
the coalesce commands are using buffers on the stack, which is causing
the device to see DMA errors. There should also be a complaint from
check_for_stack() in debug_dma_map_xyz(). Fix this by adding and using
coalesce params from the control_buf struct, which aligns with other
commands.

Commit 523847df1b37 ("pds_core: add devcmd device interfaces") included
initial support for FW recovery detection. Unfortunately, the ordering
in pdsc_is_fw_good() was incorrect, which was causing FW recovery to be
undetected by the driver. Fix this by making sure to update the cached
fw_status by calling pdsc_is_fw_running() before setting the local FW
gen.

The KSZ9477 PHY errata handling code has now been moved into the Micrel
PHY driver, so it is no longer needed inside the DSA switch driver.
Remove it.

The ksz9477 DSA switch driver is currently updating some MMD registers
on the internal port PHYs to address some chip errata. However, these
errata are really a property of the PHY itself, not the switch they are
part of, so this is kind of a layering violation. It makes more sense for
these writes to be done inside the driver which binds to the PHY and not
the driver for the containing device.
This also addresses some issues where the ordering of when these writes
are done may have been incorrect, causing the link to erratically fail to
come up at the proper speed or at all. Doing this in the PHY driver
during config_init ensures that they happen before anything else tries to
change the state of the PHY on the port.
The new code also ensures that autonegotiation is disabled during the
register writes and re-enabled afterwards, as indicated by the latest
version of the errata documentation from Microchip.
