The current implementation allocates page-sized rx buffers.
As traffic may consist of different types and sizes of packets,
in various cases, buffers are not fully used.
This change (Dynamic RX Buffers - DRB) uses part of the allocated rx
page needed for the incoming packet, and returns the rest of the
unused page to be used again as an rx buffer for future packets.
A threshold of 2K for unused space has been set in order to declare
whether the remainder of the page can be reused again as an rx buffer.
As a page may be reused, dma_sync_single_for_cpu() is added in order
to sync the memory to the CPU side after it was owned by the HW.
In addition, when the rx page can no longer be reused, it is being
unmapped using dma_page_unmap(), which implicitly syncs and then
unmaps the entire page. In case the kernel still handles the skbs
pointing to the previous buffers from that rx page, it may access
garbage pointers, caused by the implicit sync overwriting them.
The implicit dma sync is removed by replacing dma_page_unmap() with
dma_unmap_page_attrs() with DMA_ATTR_SKIP_CPU_SYNC flag.
The functionality is disabled for XDP traffic to avoid handling
several descriptors per packet.

In case user wants to configure the SFs, for example: to use only vdpa
functionality, he needs to fully probe a SF, configure what he wants,
and afterward reload the SF.
In order to save the time of the reload, local SFs will probe without
any auxiliary sub-device, so that the SFs can be configured prior to
its full probe.
The defaults of the enable_* devlink params of these SFs are set to
false.
Usage example:
Create SF:
$ devlink port add pci/0000:08:00.0 flavour pcisf pfnum 0 sfnum 11
$ devlink port function set pci/0000:08:00.0/32768 \
hw_addr 00:00:00:00:00:11 state active
Enable ETH auxiliary device:
$ devlink dev param set auxiliary/mlx5_core.sf.1 \
name enable_eth value true cmode driverinit
Now, in order to fully probe the SF, use devlink reload:
$ devlink dev reload auxiliary/mlx5_core.sf.1
At this point the user have SF devlink instance with auxiliary device
for the Ethernet functionality only.

There was a change previously to stop SR-IOV and LAG from existing on the
same interface. This was to prevent the violation of LACP (Link
Aggregation Control Protocol). The method to achieve this was to add a
no-op Rx handler onto the netdev when SR-IOV VFs were present, thus
blocking bonding, bridging, etc from claiming the interface by adding
its own Rx handler. Also, when an interface was added into a aggregate,
then the SR-IOV capability was set to false.
There are some users that have in house solutions using both SR-IOV and
bridging/bonding that this method interferes with (e.g. creating duplicate
VFs on the bonded interfaces and failing between them when the interface
fails over).
It makes more sense to provide the most functionality
possible, the restriction on co-existence of these features will be
removed. No additional functionality is currently being provided beyond
what existed before the co-existence restriction was put into place. It is
up to the end user to not implement a solution that would interfere with
existing network protocols.

====================
mlx5-updates-2023-04-20
1) Dragos Improves RX page pool, and provides some fixes to his previous
series:
1.1) Fix releasing page_pool for striding RQ and legacy RQ nonlinear case
1.2) Hook NAPIs to page pools to gain more performance.
2) From Roi, Some cleanups to TC and eswitch modules.
3) Maher migrates vnic diagnostic counters reporting from debugfs to a
dedicated devlink health reporter
Maher Says:
===========
net/mlx5: Expose vnic diagnostic counters using devlink
Currently, vnic diagnostic counters are exposed through the following
debugfs:
$ ls /sys/kernel/debug/mlx5/0000:08:00.0/esw/vf_0/vnic_diag/
cq_overrun
quota_exceeded_command
total_q_under_processor_handle
invalid_command
send_queue_priority_update_flow
nic_receive_steering_discard
The current design does not allow the hypervisor to view the diagnostic
counters of its VFs, in case the VFs get bound to a VM. In other words,
the counters are not exposed for representor interfaces.
Furthermore, the debugfs design is inconvenient future-wise, in case more
counters need to be reported by the driver in the future.
As these counters pertain to vNIC health, it is more appropriate to
utilize the devlink health reporter to expose them.
Thus, this patchest includes the following changes:
* Drop the current vnic diagnostic counters debugfs interface.
* Add a vnic devlink health reporter for PFs/VFs core devices, which
when diagnosed will dump vnic diagnostic counter values that are
queried from FW.
* Add a vnic devlink health reporter for the representor interface, which
serves the same purpose listed in the previous point, in addition to
allowing the hypervisor to view its VFs diagnostic counters, even when
the VFs are bounded to external VMs.
Example of devlink health reporter usage is:
$devlink health diagnose pci/0000:08:00.0 reporter vnic
vNIC env counters:
total_error_queues: 0 send_queue_priority_update_flow: 0
comp_eq_overrun: 0 async_eq_overrun: 0 cq_overrun: 0
invalid_command: 0 quota_exceeded_command: 0

The recycle parameter used during page release is no longer
necessary: the page pool can detect when the page cannot be
recycled to the cache or ring without any outside hint.
The page pool will also take care of cleaning up after itself
once all the inflight pages have been released. So no need to
explicitly release pages to the system.
Remove the internal page_cache stats as the mlx5e_page_cache
struct no longer exists.
Delete the documentation entries along with the stats.

The canonical location for the tracefs filesystem is at /sys/kernel/tracing.
But, from Documentation/trace/ftrace.rst:
Before 4.1, all ftrace tracing control files were within the debugfs
file system, which is typically located at /sys/kernel/debug/tracing.
For backward compatibility, when mounting the debugfs file system,
the tracefs file system will be automatically mounted at:
/sys/kernel/debug/tracing
Many parts of Documentation still reference this older debugfs path, so
let's update them to avoid confusion.

Previously support for GNSS was implemented as a TTY driver, it allowed
to access GNSS receiver on /dev/ttyGNSS_<bus><func>.
Use generic GNSS subsystem API instead of implementing own TTY driver.
The receiver is accessible on /dev/gnss<id>. In case of multiple receivers
in the OS, correct device can be found by enumerating either:
- /sys/class/net/<eth port>/device/gnss/
- /sys/class/gnss/gnss<id>/device/
Using GNSS subsystem is superior to implementing own TTY driver, as the
GNSS subsystem was designed solely for this purpose. It also implements
TTY driver but in a common and defined way.
From user perspective, there is no difference in communicating with a
device, except new path to the device shall be used. The device will
provide same information to the userspace as the old one, and can be used
in the same way, i.e.:
old # gpsmon /dev/ttyGNSS_2100_0
new # gpsmon /dev/gnss0
There is no other impact on userspace tools.
User expecting onboard GNSS receiver support is required to enable
CONFIG_GNSS=y/m in kernel config.

dpaa2_mac_is_type_fixed() is a header with no implementation and no
callers, which is referenced from the documentation though. It can be
deleted.
On the other hand, it would be useful to reuse the code between
dpaa2_eth_is_type_phy() and dpaa2_switch_port_is_type_phy(). That common
code should be called dpaa2_mac_is_type_phy(), so let's create that.
The removal and the addition are merged into the same patch because,
in fact, is_type_phy() is the logical opposite of is_type_fixed().
