====================
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
    nic_receive_steering_discard: 0

Create a vnic devlink health reporter for PFs/VFs interfaces.
The reporter's diagnose callback displays the values of vNIC/vport
transport debug counters of PFs/VFs, as follows:

$ 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
    nic_receive_steering_discard: 0

Moreover, add documentation on the reporter functionality and the
counters description.

While at it, expose the vNIC counters diagnose function to be used by
the downstream patch, which will reveal the counters for representor
interfaces.

This reverts commit fe998a3c77b9f989a30a2a01fb00d3729a6d53a4.

Paul reports that it causes a regression with IB on CX4
and FW 12.18.1000. In addition I think that the concept
of "management PF" is not fully accepted and requires
a discussion.

Commit cited in "fixes" tag added bulk support for flow counters but it
didn't account that's also possible to query a counter using a non-base id
if the counter was allocated as bulk.

When a user performs a query, validate the flow counter id given in the
mailbox is inside the valid range taking bulk value into account.

When a user performs a query, validate the flow counter id given in the
mailbox is inside the valid range taking bulk value into account.

<title>net/mlx5: Update relaxed ordering read HCA capabilities</title>

Rename existing HCA capability relaxed_ordering_read to
relaxed_ordering_read_pci_enabled. This is in accordance with recent PRM
change to better describe the capability, as it's set only if both the
device supports relaxed ordering (RO) read and RO is enabled in PCI
config space.

In addition, add new HCA capability relaxed_ordering_read which is set
if the device supports RO read, regardless of RO in PCI config space.
This will be used in the following patch to allow RO in VFs and VMs.

Patches overview:

- Patch 1 adds hardware definition bits for capabilities required to replicate
  multicast packets to multiple per-port tables. These bits are used by
  following patches to only attempt multicast offload if firmware and hardware
  provide necessary support.

- Pathces 2-4 patches are preparations and refactoring.

- Patch 5 implements necessary infrastructure to toggle multicast offload
  via SWITCHDEV_ATTR_ID_BRIDGE_MC_DISABLED port object attribute notification.
  This also enabled IGMP and MLD snooping.

- Patch 6 implements per-port multicast replication tables. It only supports
  filtering of loopback packets.

- Patch 7 extends per-port multicast tables with VLAN pop support for 'untagged'
  VLANs.

- Patch 8 handles SWITCHDEV_OBJ_ID_PORT_MDB port object notifications. It
  creates MDB replication rules in egress table that can replicate packets to
  multiple per-port multicast tables.

- Patch 9 adds tracepoints for MDB events.

==============

2) Parav Create a new allocation profile for SFs, to save on memory

3) Yevgeny provides some initial patches for upcoming software steering
   support new pattern/arguments type of modify_header actions.

Starting with ConnectX-6 DX, we use a new design of modify_header FW object.
The current modify_header object allows for having only limited number of
these FW objects, which means that we are limited in the number of offloaded
flows that require modify_header action.

As a preparation Yevgeny provides the following 4 patches:
 - Patch 1: Add required mlx5_ifc HW bits
 - Patch 2, 3: Add new WQE type and opcode that is required for pattern/arg
   support and adds appropriate support in dr_send.c
 - Patch 4: Add ICM pool for modify-header-pattern objects and implement
   patterns cache, allowing patterns reuse for different flows

Patches overview:

- Patch 1 adds hardware definition bits for capabilities required to replicate
  multicast packets to multiple per-port tables. These bits are used by
  following patches to only attempt multicast offload if firmware and hardware
  provide necessary support.

- Pathces 2-4 patches are preparations and refactoring.

- Patch 5 implements necessary infrastructure to toggle multicast offload
  via SWITCHDEV_ATTR_ID_BRIDGE_MC_DISABLED port object attribute notification.
  This also enabled IGMP and MLD snooping.

- Patch 6 implements per-port multicast replication tables. It only supports
  filtering of loopback packets.

- Patch 7 extends per-port multicast tables with VLAN pop support for 'untagged'
  VLANs.

- Patch 8 handles SWITCHDEV_OBJ_ID_PORT_MDB port object notifications. It
  creates MDB replication rules in egress table that can replicate packets to
  multiple per-port multicast tables.

- Patch 9 adds tracepoints for MDB events.

==============

2) Parav Create a new allocation profile for SFs, to save on memory

3) Yevgeny provides some initial patches for upcoming software steering
   support new pattern/arguments type of modify_header actions.

Starting with ConnectX-6 DX, we use a new design of modify_header FW object.
The current modify_header object allows for having only limited number of
these FW objects, which means that we are limited in the number of offloaded
flows that require modify_header action.

As a preparation Yevgeny provides the following 4 patches:
 - Patch 1: Add required mlx5_ifc HW bits
 - Patch 2, 3: Add new WQE type and opcode that is required for pattern/arg
   support and adds appropriate support in dr_send.c
 - Patch 4: Add ICM pool for modify-header-pattern objects and implement
   patterns cache, allowing patterns reuse for different flows
