devlink: Support setting max_io_eqs

2024-04-08T13:10:45+00:00

Many devices send event notifications for the IO queues,
such as tx and rx queues, through event queues.

Enable a privileged owner, such as a hypervisor PF, to set the number
of IO event queues for the VF and SF during the provisioning stage.

example:
Get maximum IO event queues of the VF device::

  $ devlink port show pci/0000:06:00.0/2
  pci/0000:06:00.0/2: type eth netdev enp6s0pf0vf1 flavour pcivf pfnum 0 vfnum 1
      function:
          hw_addr 00:00:00:00:00:00 ipsec_packet disabled max_io_eqs 10

Set maximum IO event queues of the VF device::

  $ devlink port function set pci/0000:06:00.0/2 max_io_eqs 32

  $ devlink port show pci/0000:06:00.0/2
  pci/0000:06:00.0/2: type eth netdev enp6s0pf0vf1 flavour pcivf pfnum 0 vfnum 1
      function:
          hw_addr 00:00:00:00:00:00 ipsec_packet disabled max_io_eqs 32

Documentation: Fix counter name of mlx5 vnic reporter

2024-02-06T00:45:50+00:00

Fix counter name in documentation of mlx5 vnic health reporter diagnose
output: total_error_queues.

While here fix alignment in the documentation file of another counter,
comp_eq_overrun, as it should have its own line and not be part of
another counter's description.

Example:
$ devlink health diagnose  pci/0000:00:04.0 reporter vnic
 vNIC env counters:
    total_error_queues: 0 send_queue_priority_update_flow: 0

Documentation: mlx5.rst: Add note for eswitch MD

2024-01-27T14:29:20+00:00

Add a note when using esw_port_metadata. The parameter has runtime
mode but setting it does not take effect immediately. Setting it must
happen in legacy mode, and the port metadata takes effects when the
switchdev mode is enabled.

Disable eswitch port metadata::
  $ devlink dev param set pci/0000:06:00.0 name esw_port_metadata value \
    false cmode runtime
Change eswitch mode to switchdev mode where after choosing the metadata value::
  $ devlink dev eswitch set pci/0000:06:00.0 mode switchdev

Note that other mlx5 devlink runtime parameters, esw_multiport and
flow_steering_mode, do not have this limitation.
