When both the RHBA and RPA FDMI requests time out, fnic reuses a frame to
send ABTS for each of them. On send completion, this causes an attempt to
free the same frame twice that leads to a crash.
Fix crash by allocating separate frames for RHBA and RPA, and modify ABTS
logic accordingly.
Tested by checking MDS for FDMI information.
Tested by using instrumented driver to:
- Drop PLOGI response
- Drop RHBA response
- Drop RPA response
- Drop RHBA and RPA response
- Drop PLOGI response + ABTS response
- Drop RHBA response + ABTS response
- Drop RPA response + ABTS response
- Drop RHBA and RPA response + ABTS response for both of them

With the ATA error model, an NCQ command failure always triggers an abort
(termination) of all NCQ commands queued on the device. In such case, the
SAT or the host must handle the failed command according to the command
sense data and immediately retry all other NCQ commands that were aborted
due to the failed NCQ command.
For SAS HBAs controlled by the mpt3sas driver, NCQ command aborts are not
handled by the HBA SAT and sent back to the host, with an ioc log
information equal to 0x31080000 (IOC_LOGINFO_PREFIX_PL with the PL code
PL_LOGINFO_CODE_SATA_NCQ_FAIL_ALL_CMDS_AFTR_ERR). The function
_scsih_io_done() always forces a retry of commands terminated with the
status MPI2_IOCSTATUS_SCSI_IOC_TERMINATED using the SCSI result
DID_SOFT_ERROR, regardless of the log_info for the command. This
correctly forces the retry of collateral NCQ abort commands, but with the
retry counter for the command being incremented. If a command to an ATA
device is subject to too many retries due to other NCQ commands failing
(e.g. read commands trying to access unreadable sectors), the collateral
NCQ abort commands may be terminated with an error as they run out of
retries. This violates the SAT specification and causes hard-to-debug
command errors.
Solve this issue by modifying the handling of the
MPI2_IOCSTATUS_SCSI_IOC_TERMINATED status to check if a command is for an
ATA device and if the command loginfo indicates an NCQ collateral
abort. If that is the case, force the command retry using the SCSI result
DID_IMM_RETRY to avoid incrementing the command retry count.

For some PWMs applying a configuration doesn't sleep. For these enabling
and disabling can be done in the clk callbacks .enable() and .disable()
instead of .prepare() and .unprepare().
Do that to possibly reduce the time the PWM is enabled and so save some

pwm_config() is an old function that I'd like to remove. So convert this
driver to use pwm_apply_might_sleep().
There is a minor change in behaviour as the explicitly calculated
duty_cycle used an uprounding division while pwm_set_relative_duty_cycle()
rounds down. I don't expect that difference to matter in practice though.

The SCMI clock driver currently assumes that parent clocks are always
initialized before their children. However, this assumption can fail if
a child clock is encountered before its parent during probe.
This leads to an issue during initialization of the parent_data array:
sclk->parent_data[i].hw = hws[sclk->info->parents[i]];
If the parent clock's hardware structure has not been initialized yet,
this assignment results in invalid data.
To resolve this, allocate all struct scmi_clk instances as a contiguous
array at the beginning of the probe and populate the hws[] array
upfront. This ensures that any parent referenced later is already
initialized, regardless of the order in which clocks are processed.
Note that we can no longer free individual scmi_clk instances if
scmi_clk_ops_init() fails which shouldn't be a problem if the SCMI
platform has proper per-agent clock discovery.

'ref_tracker-add-ability-to-register-a-debugfs-file-for-a-ref_tracker_dir'
Jeff Layton says:
====================
ref_tracker: add ability to register a debugfs file for a ref_tracker_dir
For those just joining in, this series adds a new top-level
"ref_tracker" debugfs directory, and has each ref_tracker_dir register a
file in there as part of its initialization. It also adds the ability to
register a symlink with a more human-usable name that points to the
file, and does some general cleanup of how the ref_tracker object names
are handled.

A later patch in the series will be adding debugfs files for each
ref_tracker that get created in ref_tracker_dir_init(). The format will
be "class@%px". The current "name" string can vary between
ref_tracker_dir objects of the same type, so it's not suitable for this
purpose.
Add a new "class" string to the ref_tracker dir that describes the
the type of object (sans any individual info for that object).
Also, in the i915 driver, gate the creation of debugfs files on whether
the dentry pointer is still set to NULL. CI has shown that the
ref_tracker_dir can be initialized more than once.

Replace custom statistics tracking with the kernel's dstats infrastructure
to simplify code and improve consistency with other network drivers.
This change:
- Sets dev->pcpu_stat_type = NETDEV_PCPU_STAT_DSTATS for automatic
automatic allocation and deallocation.
- Removes manual stats fields and their update
- Replaces custom nsim_get_stats64() with dev_get_stats()
- Uses dev_dstats_tx_add() and dev_dstats_tx_dropped() helpers
- Eliminates the need for manual synchronization primitives
The dstats framework provides the same functionality with less code.

MANA supports RDMA in PF mode. The driver should record the doorbell
physical address when in PF mode.
The doorbell physical address is used by the RDMA driver to map
doorbell pages of the device to user-mode applications through RDMA
verbs interface. In the past, they have been mapped to user-mode while
the device is in VF mode. With the support for PF mode implemented,
also expose those pages in PF mode.
Support for PF mode is implemented in

Refactor Energy-Efficient Ethernet (EEE) support in the LAN78xx driver to

- Replacing direct calls to `phy_ethtool_get_eee` and `phy_ethtool_set_eee`
with `phylink_ethtool_get_eee` and `phylink_ethtool_set_eee`.
- Implementing `.mac_enable_tx_lpi` and `.mac_disable_tx_lpi` to control
LPI transitions via phylink.
- Configuring `lpi_timer_default` to align with recommended values from
LAN7800 documentation.
- ensure EEE is disabled on controller reset

Refactor lan78xx_get_link_ksettings and lan78xx_set_link_ksettings to
use the phylink API (phylink_ethtool_ksettings_get and
phylink_ethtool_ksettings_set) instead of directly interfacing with the
PHY. This change simplifies the code and ensures better integration with
the phylink framework for link management.
Additionally, the explicit calls to usb_autopm_get_interface() and
usb_autopm_put_interface() have been removed. These were originally
needed to manage USB power management during register accesses. However,
lan78xx_mdiobus_read() and lan78xx_mdiobus_write() already handle USB
auto power management internally, ensuring that the interface remains
active when necessary. Since there are no other direct register accesses
in these functions that require explicit power management handling, the
extra calls have become redundant and are no longer needed.

The EVENT_LINK_RESET macro currently triggers deferred work after a PHY
interrupt. Prior to PHYLINK conversion, this work included reconfiguring
the MAC and PHY, effectively performing a 'link reset'.
However, after porting the driver to the PHYLINK framework, the logic
associated with this event now solely handles the acknowledgment of
the PHY interrupt. The MAC and PHY reconfiguration is now managed by
PHYLINK's dedicated callbacks.
To accurately reflect its current, narrowed functionality, rename
EVENT_LINK_RESET to EVENT_PHY_INT_ACK.

Convert the LAN78xx USB Ethernet driver to use the PHYLINK framework for
managing PHY and MAC interactions. This improves consistency with other
network drivers, simplifies pause frame handling, and enables cleaner
suspend/resume support.
Key changes:
- Replace all PHYLIB-based logic with PHYLINK equivalents:
- Replace phy_connect()/phy_disconnect() with phylink_connect_phy()
- Replace phy_start()/phy_stop() with phylink_start()/phylink_stop()
- Replace pauseparam handling with phylink_ethtool_get/set_pauseparam()
- Introduce lan78xx_phylink_setup() to configure PHYLINK
- Add phylink MAC operations:
- lan78xx_mac_config()
- lan78xx_mac_link_up()
- lan78xx_mac_link_down()
- Remove legacy link state handling:
- lan78xx_link_status_change()
- lan78xx_link_reset()
- Handle fixed-link fallback for LAN7801 using phylink_set_fixed_link()
- Replace deprecated flow control handling with phylink-managed logic
Power management:
- Switch suspend/resume paths to use phylink_suspend()/phylink_resume()
- Ensure proper use of rtnl_lock() where required
- Note: full runtime testing of power management is currently limited
due to hardware setup constraints
Note: Conversion of EEE (Energy Efficient Ethernet) handling to the
PHYLINK-managed API will be done in a follow-up patch. For now, the
legacy EEE enable logic is preserved in mac_link_up().
