net: dsa: microchip: ksz8: fixes for stable

changes v2:
- use proper Fixes tag
- add Acked-by: Arun Ramadoss <arun.ramadoss@microchip.com> on all
  reviewed patches except the ksz8863_smi patch.

These fixes address issues such as incomplete FDB extraction, incorrect
FID extraction and configuration, incorrect timestamp extraction, and
ghost entry extraction from an empty dynamic MAC table. These updates
ensure proper functioning of the FDB/MDB functionality for the
ksz8863/ksz8873 series of chips.

FID is directly mapped to VID. However, configuring a MAC address with a
VID != 0 resulted in incorrect configuration due to an incorrect bit
mask. This kernel commit fixed the issue by correcting the bit mask and
ensuring proper configuration of MAC addresses with non-zero VID.

Current regmap bulk access is broken, resulting to wrong reads/writes
if ksz_read64/ksz_write64 functions are used.
Mostly this issue was visible by using ksz8_fdb_dump(), which returned
corrupt MAC address.

The reason is that regmap was configured to have max_raw_read/write,
even if ksz8863_mdio_read/write functions are able to handle unlimited
read/write accesses. On ksz_read64 function we are using multiple 32bit
accesses by incrementing each access by 1 instead of 4. Resulting buffer
had 01234567.12345678 instead of 01234567.89abcdef.

We have multiple ways to fix it:
- enable 4 byte alignment for 32bit accesses. Since the HW do not have
  this requirement. It will break driver.
- disable max_raw_* limit.

This patch is removing max_raw_* limit for regmap accesses in ksz8863_smi.

Smatch complains that:
drivers/ptp/ptp_qoriq.c ptp_qoriq_probe()
warn: 'base' from ioremap() not released.

Fix this by revising the parameter from 'ptp_qoriq->base' to 'base'.
This is only a bug if ptp_qoriq_init() returns on the
first -ENODEV error path.
For other error paths ptp_qoriq->base and base are the same.
And this change makes the code more readable.

Currently, vmxnet3 uses GRO callback only if LRO is disabled. However,
on smartNic based setups where UPT is supported, LRO can be enabled
from guest VM but UPT devicve does not support LRO as of now. In such
cases, there can be performance degradation as GRO is not being done.

This patch fixes this issue by calling GRO API when UPT is enabled. We
use updateRxProd to determine if UPT mode is active or not.

To clarify few things discussed over the thread:
The patch is not neglecting any feature bits nor disabling GRO. It uses
GRO callback when UPT is active as LRO is not available in UPT.
GRO callback cannot be used as default for all cases as it degrades
performance for non-UPT cases or for cases when LRO is already done in
ESXi.

The probe function sets priv->chip_data to (void *)priv + sizeof(*priv)
with the expectation that priv has enough trailing space.

However, only realtek-smi actually allocated this chip_data space.
Do likewise in realtek-mdio to fix out-of-bounds accesses.

These accesses likely went unnoticed so far, because of an (unused)
buf[4096] member in struct realtek_priv, which caused kmalloc to
round up the allocated buffer to a big enough size, so nothing of
value was overwritten. With a different allocator (like in the barebox
bootloader port of the driver) or with KASAN, the memory corruption
becomes quickly apparent.

dp83869 internally uses a look-up table for mapping supported delays in
nanoseconds to register values.
When specific delays are defined in device-tree, phy_get_internal_delay
does the lookup automatically returning an index.

The default case wrongly assigns the nanoseconds value from the lookup
table, resulting in numeric value 2000 applied to delay configuration
register, rather than the expected index values 0-7 (7 for 2000).
Ultimately this issue broke RX for 1Gbps links.

Fix default delay configuration by assigning the intended index value
directly.

At NIC reset, some offload features related to encapsulated traffic
might have changed (this mainly happens if the firmware-variant is
changed with the sfboot userspace tool). Because of this, features are
checked and set again at reset time.

However, this was not done right, and some features were improperly
overwritten at NIC reset:
- Tunneled IPv6 segmentation was always disabled
- Features disabled with ethtool were reenabled
- Features that becomes unsupported after the reset were not disabled

Also, checking if the device supports IPV6_CSUM to enable TSO6 is no
longer necessary because all currently supported devices support it.
Additionally, move the assignment of some other features to the
EF10_OFFLOAD_FEATURES macro, like it is done in ef100, leaving the
selection of features in efx_pci_probe_post_io a bit cleaner.

To loop a variable-length array, hci_init_stage_sync(stage) considers
that stage[i] is valid as long as stage[i-1].func is valid.
Thus, the last element of stage[].func should be intentionally invalid
as hci_init0[], le_init2[], and others did.
However, amp_init1[] and amp_init2[] have no invalid element, letting
hci_init_stage_sync() keep accessing amp_init1[] over its valid range.

On most devices using the btqcomsmd driver (e.g. the DragonBoard 410c
and other devices based on the Qualcomm MSM8916/MSM8909/... SoCs)
the Bluetooth firmware seems to become unresponsive for a while after
setting the BD address. On recent kernel versions (at least 5.17+)
this often causes timeouts for subsequent commands, e.g. the HCI reset
sent by the Bluetooth core during initialization:

    Bluetooth: hci0: Opcode 0x c03 failed: -110

Unfortunately this behavior does not seem to be documented anywhere.
Experimentation suggests that the minimum necessary delay to avoid
the problem is ~150us. However, to be sure add a sleep for > 1ms
in case it is a bit longer on other firmware versions.

Older kernel versions are likely also affected, although perhaps with
slightly different errors or less probability. Side effects can easily
hide the issue in most cases, e.g. unrelated incoming interrupts that
cause the necessary delay.

It turns out that reverting commit 970343cd ("GFS2: free disk inode

evicting inodes that were unlinked on a different cluster node.

We could also have simply added a call to d_mark_dontcache() to function
gfs2_try_evict(), but the original pre-revert code is better tested and
proven.

Move lowering the TRGMII Tx clock driving to mt7530_setup(), after setting

Move the code which looks like it lowers the TRGMII Rx clock driving to
after the TRGMII Tx clock driving is lowered. This is run after lowering
the Tx clock driving on the U-Boot MediaTek ethernet driver as well.

This way, the switch should consume less power regardless of port 6 being
used.

"modprobe asix ; rmmod asix ; modprobe asix" fails with:
   sysfs: cannot create duplicate filename \
   	'/devices/virtual/mdio_bus/usb-003:004'

Issue was originally reported by Anton Lundin on 2022-06-22 (link below).

Chrome OS team hit the same issue in Feb, 2023 when trying to find
work arounds for other issues with AX88172 devices.

The use of devm_mdiobus_register() with usbnet devices results in the
MDIO data being associated with the USB device. When the asix driver
is unloaded, the USB device continues to exist and the corresponding
"mdiobus_unregister()" is NOT called until the USB device is unplugged
or unauthorized. So the next "modprobe asix" will fail because the MDIO
phy sysfs attributes still exist.

The 'easy' (from a design PoV) fix is to use the non-devm variants of
mdiobus_* functions and explicitly manage this use in the asix_bind
and asix_unbind function calls. I've not explored trying to fix usbnet
initialization so devm_* stuff will work.

The link speed is never changed for the uptime of a VM, and the current
implementation sends an admin queue command for each call. Admin queue
command invocations have nontrivial overhead (e.g., VM exits), which can
be disruptive to users if triggered frequently. Our telemetry data shows
that there are VMs that make frequent calls to this admin queue command.
Caching the result of the original admin queue command would eliminate
the need to send multiple admin queue commands on subsequent calls to
retrieve link speed.
