phylink
The function allows for the configuration of a fixed link state for a given
phylink instance. This addition is particularly useful for network devices that
operate with a fixed link configuration, where the link parameters do not change
dynamically. By using `phylink_set_fixed_link()`, drivers can easily set up
the fixed link state during initialization or configuration changes.

After commit 0edb555a65d1 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.
Convert all can drivers to use .remove(), with the eventual goal to drop
struct platform_driver::remove_new(). As .remove() and .remove_new() have
the same prototypes, conversion is done by just changing the structure
member name in the driver initializer.

for non-continous port maps"
This reverts commit ab8d66d132bc8f1992d3eb6cab8d32dda6733c84 because it
breaks codecs using non-continuous masks in source and sink ports. The
commit missed the point that port numbers are not used as indices for
iterating over prop.sink_ports or prop.source_ports.
Soundwire core and existing codecs expect that the array passed as
prop.sink_ports and prop.source_ports is continuous. The port mask still
might be non-continuous, but that's unrelated.

Since recently in the commit e469e2045f1b ("ALSA: memalloc: Let IOMMU
handle S/G primarily"), the SG buffer allocation code was modified to
use the standard DMA code primarily and the fallback is applied only
limitedly. This made the Xen PV specific workarounds we took in the
commit 53466ebdec61 ("ALSA: memalloc: Workaround for Xen PV") rather
superfluous.
It was a hackish workaround for the regression at that time, and it
seems that it's causing another issues (reportedly memory
corruptions). So it's better to clean it up, after all.

The icache will be flushed in switch_to() if force_icache_flush is true,
or in flush_icache_deferred() if icache_stale_mask is set. Between
setting force_icache_flush to false and calculating the new
icache_stale_mask, preemption needs to be disabled. There are two
reasons for this:
1. If CPU migration happens between force_icache_flush = false, and the
icache_stale_mask is set, an icache flush will not be emitted.
2. smp_processor_id() is used in set_icache_stale_mask() to mark the
current CPU as not needing another flush since a flush will have
happened either by userspace or by the kernel when performing the
migration. smp_processor_id() is currently called twice with preemption
enabled which causes a race condition. It allows
icache_stale_mask to be populated with inconsistent CPU ids.
Resolve these two issues by setting the icache_stale_mask before setting
force_icache_flush to false, and using get_cpu()/put_cpu() to obtain the
smp_processor_id().

ice: support devlink subfunction
Michal Swiatkowski says:
Currently ice driver does not allow creating more than one networking
device per physical function. The only way to have more hardware backed
netdev is to use SR-IOV.
Following patchset adds support for devlink port API. For each new
pcisf type port, driver allocates new VSI, configures all resources
needed, including dynamically MSIX vectors, program rules and registers
new netdev.
This series supports only one Tx/Rx queue pair per subfunction.
Example commands:
devlink port add pci/0000:31:00.1 flavour pcisf pfnum 1 sfnum 1000
devlink port function set pci/0000:31:00.1/1 hw_addr 00:00:00:00:03:14
devlink port function set pci/0000:31:00.1/1 state active
devlink port function del pci/0000:31:00.1/1
Make the port representor and eswitch code generic to support
subfunction representor type.
VSI configuration is slightly different between VF and SF. It needs to
be reflected in the code.

HW-Managed Flow Steering in mlx5 driver
Yevgeny Kliteynik says:
=======================
1. Overview
-----------
ConnectX devices support packet matching, modification, and redirection.
This functionality is referred as Flow Steering.
To configure a steering rule, the rule is written to the device-owned
memory. This memory is accessed and cached by the device when processing
a packet.
The first implementation of Flow Steering was done in FW, and it is
referred in the mlx5 driver as Device-Managed Flow Steering (DMFS).
Later we introduced SW-managed Flow Steering (SWS or SMFS), where the
driver is writing directly to the device's configuration memory (ICM)
through RC QP using RDMA operations (RDMA-read and RDAM-write), thus
achieving higher rates of rule insertion/deletion.
Now we introduce a new flow steering implementation: HW-Managed Flow
Steering (HWS or HMFS).
In this new approach, the driver is configuring steering rules directly
to the HW using the WQs with a special new type of WQE. This way we can
reach higher rule insertion/deletion rate with much lower CPU utilization
compared to SWS.
The key benefits of HWS as opposed to SWS:
+ HW manages the steering decision tree
- HW calculates CRC for each entry
- HW handles tree hash collisions
- HW & FW manage objects refcount
+ HW keeps cache coherency:
- HW provides tree access locking and synchronization
- HW provides notification on completion
+ Insertion rate isn’t affected by background traffic
- Dedicated HW components that handle insertion
2. Performance
--------------
Measuring Connection Tracking with simple IPv4 flows w/o NAT, we
are able to get ~5 times more flows offloaded per second using HWS.
3. Configuration
----------------
The enablement of HWS mode in eswitch manager is done using the same
devlink param that is already used for switching between FW-managed
steering and SW-managed steering modes:
# devlink dev param set pci/<PCI_ID> name flow_steering_mode cmod runtime value hmfs
4. Upstream Submission
----------------------
HWS support consists of 3 main components:
+ Steering:
- The lower layer that exposes HWS API to upper layers and implements
all the management of flow steering building blocks
+ FS-Core
- Implementation of fs_hws layer to enable fs_core to use HWS instead
of FW or SW steering
- Create HW steering action pools to utilize the ability of HWS to
share steering actions among different rules
- Add support for configuring HWS mode through devlink command,
similar to configuring SWS mode
+ Connection Tracking
- Implementation of CT support for HW steering
- Hooks up the CT ops for the new steering mode and uses the HWS API
to implement connection tracking.
Because of the large number of patches, we need to perform the submission
in several separate patch series. This series is the first submission that
lays the ground work for the next submissions, where an actual user of HWS
will be added.
5. Patches in this series
-------------------------
This patch series contains implementation of the first bullet from above.

bnxt_en: MSIX improvements
This patchset makes some improvements related to MSIX. The first
patch adjusts the default MSIX vectors assigned for RoCE. On the
PF, the number of MSIX is increased to 64 from the current 9. The
second patch allocates additional MSIX vectors ahead of time when
changing ethtool channels if dynamic MSIX is supported. The 3rd
patch makes sure that the IRQ name is not truncated.

The name field of struct bnxt_irq is written using snprintf in
bnxt_setup_msix(). Make the field large enough to fit the maximal
formatted string to prevent truncation. Truncated IRQ names are
less meaningful to the user. For example, "enp4s0f0np0-TxRx-0"
gets truncated to "enp4s0f0np0-TxRx-" with the existing code.
Make sure we have space for the extra characters added to the IRQ
names:
- the characters introduced by the static format string: hyphens
- the maximal static substituted ring type string: "TxRx"
- the maximum length of an integer formatted as a string, even
though reasonable ring numbers would never be as long as this.

bnxt_check_rings() is called to ensure that we have the hardware ring
resources before committing to reinitialize with the new number of
rings. MSIX vectors are never checked at this point, because up
until recently we must first disable MSIX before we can allocate the
new set of MSIX vectors.
Now that we support dynamic MSIX allocation, check to make sure we
can dynamically allocate the new MSIX vectors as the last step in
bnxt_check_rings() if dynamic MSIX is supported.
For example, the IOMMU group may limit the number of MSIX vectors
for the device. With this patch, the ring change will fail more
gracefully when there is not enough MSIX vectors.
It is also better to move bnxt_check_rings() to be called as the last
step when changing ethtool rings.

If RocE is supported on the device, set the number of RoCE MSIX vectors
to the number of online CPUs + 1 and capped at these maximums:
VF: 2
NPAR: 5
PF: 64
For the PF, the maximum is now increased from the previous value
of 9 to get better performance for kernel applications.
Remove the unnecessary check for BNXT_FLAG_ROCE_CAP.
bnxt_set_dflt_ulp_msix() will only be called if the flag is set.

sch_cake uses a cache of the first 16 values of the inverse square root
calculation for the Cobalt AQM to save some cycles on the fast path.
This cache is populated when the qdisc is first loaded, but there's
really no reason why it can't just be pre-populated. So change it to be
pre-populated with constants, which also makes it possible to constify
it.
This gives a modest space saving for the module (not counting debug data):
