Testing in two circumstances:
1. back to back optical SFP+ connection between two LS1028A-QDS ports
with the SCH-26908 riser card
2. T1042 with on-board AQR115 PHY using "OCSGMII", as per
https://lore.kernel.org/lkml/aIuEvaSCIQdJWcZx@FUE-ALEWI-WINX/
strongly suggests that enabling in-band auto-negotiation is actually
possible when the lane baud rate is 3.125 Gbps.
It was previously thought that this would not be the case, because it
was only tested on 2500base-x links with on-board Aquantia PHYs, where
it was noticed that MII_LPA is always reported as zero, and it was
thought that this is because of the PCS.
Test case #1 above shows it is not, and the configured MII_ADVERTISE on
system A ends up in the MII_LPA on system B, when in 2500base-x mode
(IF_MODE=0).
Test case #2, which uses "SGMII" auto-negotiation (IF_MODE=3) for the
3.125 Gbps lane, is actually a misconfiguration, but it is what led to
the discovery.
There is actually an old bug in the Lynx PCS driver - it expects all
register values to contain their default out-of-reset values, as if the
PCS were initialized by the Reset Configuration Word (RCW) settings.
There are 2 cases in which this is problematic:
- if the bootloader (or previous kexec-enabled Linux) wrote a different
IF_MODE value
- if dynamically changing the SerDes protocol from 1000base-x to
2500base-x, e.g. by replacing the optical SFP module.
Specifically in test case #2, an accidental alignment between the
bootloader configuring the PCS to expect SGMII in-band code words, and
the AQR115 PHY actually transmitting SGMII in-band code words when
operating in the "OCSGMII" system interface protocol, led to the PCS
transmitting replicated symbols at 3.125 Gbps baud rate. This could only
have happened if the PCS saw and reacted to the SGMII code words in the
first place.
Since test #2 is invalid from a protocol perspective (there seems to be
no standard way of negotiating the data rate of 2500 Mbps with SGMII,
and the lower data rates should remain 10/100/1000), in-band auto-negotiation
for 2500base-x effectively means Clause 37 (i.e. IF_MODE=0).
Make 2500base-x be treated like 1000base-x in this regard, by removing
all prior limitations and calling lynx_pcs_config_giga().
This adds a new feature: LINK_INBAND_ENABLE and at the same time fixes
the Lynx PCS's long standing problem that the registers (specifically
IF_MODE, but others could be misconfigured as well) are not written by
the driver to the known valid values for 2500base-x.

nvme_fc_ctrl_put can acquire the rport lock when freeing the
ctrl object:
nvme_fc_ctrl_put
nvme_fc_ctrl_free
spin_lock_irqsave(rport->lock)
Thus we can't hold the rport lock when calling nvme_fc_ctrl_put.
Justin suggested use the safe list iterator variant because
nvme_fc_ctrl_put will also modify the rport->list.

Currently, nvmet_pci_epf_init_dma() has two dev_dbg() calls intended to
print debug information about the DMA channels for RX and TX. However,
both calls mistakenly are made for the TX channel. Fix it by referreing
to 'nvme_epf->rx_chan' and 'nvme_epf->tx_chan' and instead of the local
variable 'chan'.

For DMA initialization to work across all EPC drivers, the DMA
initialization has to be done in the .init() callback.
This is because not all EPC drivers will have a refclock (which is often
needed to access registers of a DMA controller embedded in a PCIe
controller) at the time the .bind() callback is called.
However, all EPC drivers are guaranteed to have a refclock by the time
the .init() callback is called.
Thus, move the DMA initialization to the .init() callback.
This change was already done for other EPF drivers in
commit 60bd3e039aa2 ("PCI: endpoint: pci-epf-{mhi/test}: Move DMA
initialization to EPC init callback").

Pull cred guard updates from Christian Brauner:
"This contains substantial credential infrastructure improvements
adding guard-based credential management that simplifies code and
eliminates manual reference counting in many subsystems.
Features:
- Kernel Credential Guards
Add with_kernel_creds() and scoped_with_kernel_creds() guards that
allow using the kernel credentials without allocating and copying
them. This was requested by Linus after seeing repeated
prepare_kernel_creds() calls that duplicate the kernel credentials
only to drop them again later.
The new guards completely avoid the allocation and never expose the
temporary variable to hold the kernel credentials anywhere in
callers.
- Generic Credential Guards
Add scoped_with_creds() guards for the common override_creds() and
revert_creds() pattern. This builds on earlier work that made
override_creds()/revert_creds() completely reference count free.
- Prepare Credential Guards
Add prepare credential guards for the more complex pattern of
preparing a new set of credentials and overriding the current
credentials with them:
- prepare_creds()
- modify new creds
- override_creds()
- revert_creds()
- put_cred()
Cleanups:
- Make init_cred static since it should not be directly accessed
- Add kernel_cred() helper to properly access the kernel credentials
- Fix scoped_class() macro that was introduced two cycles ago
- coredump: split out do_coredump() from vfs_coredump() for cleaner
credential handling
- coredump: move revert_cred() before coredump_cleanup()
- coredump: mark struct mm_struct as const
- coredump: pass struct linux_binfmt as const
- sev-dev: use guard for path"

The new platform uses the QCA2066 chip along with a new board ID, which
requires a dedicated firmware file to ensure proper initialization.
Without this entry, the driver cannot locate and load the correct
firmware, resulting in Bluetooth bring-up failure.
This patch adds a new entry to the firmware table for QCA2066 so that
the driver can correctly identify the board ID and load the appropriate
firmware from 'qca/QCA2066/' in the linux-firmware repository.

Some Qualcomm Bluetooth controllers, e.g., QCNFA765 with WCN6855
chip, send debug packets as ACL frames with header 0x2EDC.
The kernel misinterprets these as malformed ACL packets, causing
repeated errors:
Bluetooth: hci0: ACL packet for unknown connection handle 3804
This can occur hundreds of times per minute, greatly cluttering logs.
On my computer, I am observing approximately 7 messages per second
when streaming audio to a speaker.
For Qualcomm controllers exchanging over UART, hci_qca.c already
filters out these debug packets. This patch is for controllers
not going through UART, but USB.
This patch uses the classify_pkt_type callback to reclassify the
packets with handle 0x2EDC as HCI_DIAG_PKT before they reach the
HCI layer. This change is only applied to Qualcomm devices marked
as BTUSB_QCA_WCN6855.

The UART-based H5 protocol supports CRC data integrity checks for
reliable packets. The host sets bit 5 in the configuration field of the
CONFIG link control message to indicate that CRC is supported. The
controller sets the same bit in the CONFIG RESPONSE message to indicate
that CRC may be used from then on.

Previously, h5_open() called h5_link_control() to send a SYNC message.
But h5_link_control() only enqueues the packet and requires the caller
to call hci_uart_tx_wakeup(). Thus, after H5_SYNC_TIMEOUT ran out
(100ms), h5_timed_event() would be called and, realizing that the state
was still H5_UNINITIALIZED, it would re-enqueue the SYNC and call
hci_uart_tx_wakeup(). Consequently, two SYNC packets would be sent and
initialization would unnecessarily wait for 100ms.
The naive solution of calling hci_uart_tx_wakeup() in h5_open() does not
work because it will only schedule tx work if the HCI_PROTO_READY bit is
set and hci_serdev only sets it after h5_open() returns. This patch
removes the extraneous SYNC being enqueued and makes h5_timed_event()
wake up on the next jiffy.

Support the platform Bluetooth to be reset by hardware pin,
when a Bluetooth exception occurs, attempt to reset the
Bluetooth module using the hardware reset pin, as this
method is generally more stable and reliable than a
software reset. If the hardware reset pin is not specified
in the device tree, fall back to the existing software
reset mechanism to ensure backward compatibility.

however, this would also incorrectly set the per-cpu migration
task's->sched_class to rt_sched_class, even after unload, the per-cpu
migration task's->sched_class remains sched_rt_class.

l2tp_dfs_seq_tunnel_show prints two groups of tunnel statistics. The
first group reports transmit counters, but the code labels it as rx.
Set the label to "tx" so the debugfs output reflects the actual meaning.

New NIPA installation had been reporting a few flaky tests.
arp_ndisc_evict_nocarrier is most flaky of them all.
I suspect that the flakiness is due to udev swapping the MAC
addresses on the interfaces. Extend the message in
arp_ndisc_evict_nocarrier to hint at this potential issue.
Having the neigh get fail right after ping is rather unusual,
unless udev changes the MAC addr causing a flush in the meantime.

Following up on the old discussion [1]. Let the BaseExceptions out of
defer()'ed cleanup. And handle it in the main loop. This allows us to
exit the tests if user hit Ctrl-C during defer().

This patch fixes multiple spelling mistakes in dl2k driver comments:
- "deivices" -> "devices"
- "Ttransmit" -> "Transmit"
- "catastronphic" -> "catastrophic"
- "Extened" -> "Extended"
Also fix incorrect unit description: `rx_timeout` uses 640ns increments,
not 64ns.
- "64ns" -> "640ns"
These are comment-only changes and do not affect runtime behavior.

Breno Leitao says:
====================
net: freescale: migrate to .get_rx_ring_count() ethtool callback
This series migrates Freescale network drivers to use the new .get_rx_ring_count()
ethtool callback introduced in commit 84eaf4359c36 ("net: ethtool: add
get_rx_ring_count callback to optimize RX ring queries").
The new callback simplifies the .get_rxnfc() implementation by removing
ETHTOOL_GRXRINGS handling and moving it to a dedicated callback. This provides
a cleaner separation of concerns and aligns these drivers with the modern
ethtool API.
The series updates the following Freescale drivers:
- enetc
- dppa2
- gianfar

Convert the enetc driver to use the new .get_rx_ring_count
ethtool operation instead of implementing .get_rxnfc for handling
ETHTOOL_GRXRINGS command. This simplifies the code in two ways:
1. For enetc_get_rxnfc(): Remove the ETHTOOL_GRXRINGS case from the
switch statement while keeping other cases for classifier rules.
2. For enetc4_get_rxnfc(): Remove it completely and use
enetc_get_rxnfc() instead.
Now on, enetc_get_rx_ring_count() is the callback that returns the
number of RX rings for enetc driver.
Also, remove the documentation around enetc4_get_rxnfc(), which was not
matching what the function did(?!).

Convert the dpaa2 driver to use the new .get_rx_ring_count
ethtool operation instead of implementing .get_rxnfc for handling
ETHTOOL_GRXRINGS command. This simplifies the code by removing the
ETHTOOL_GRXRINGS case from the switch statement and replacing it with
a direct return of the queue count.
The driver still maintains .get_rxnfc for other commands including
ETHTOOL_GRXCLSRLCNT, ETHTOOL_GRXCLSRULE, and ETHTOOL_GRXCLSRLALL.
