  net/mlx5: Implement management PF Ethernet profile (2023-12-20 16:54:27 -0800)

----------------------------------------------------------------
mlx5-updates-2023-12-20

mlx5 Socket direct support and management PF profile.

Tariq Says:
===========
Support Socket-Direct multi-dev netdev

This series adds support for combining multiple devices (PFs) of the
same port under one netdev instance. Passing traffic through different
devices belonging to different NUMA sockets saves cross-numa traffic and
allows apps running on the same netdev from different numas to still
feel a sense of proximity to the device and achieve improved
performance.

We achieve this by grouping PFs together, and creating the netdev only
once all group members are probed. Symmetrically, we destroy the netdev
once any of the PFs is removed.

The channels are distributed between all devices, a proper configuration
would utilize the correct close numa when working on a certain app/cpu.

We pick one device to be a primary (leader), and it fills a special
role.  The other devices (secondaries) are disconnected from the network
in the chip level (set to silent mode). All RX/TX traffic is steered
through the primary to/from the secondaries.

Currently, we limit the support to PFs only, and up to two devices
(sockets).

Armen Says:
===========
Management PF support and module integration

This patch rolls out comprehensive support for the Management Physical
Function (MGMT PF) within the mlx5 driver. It involves updating the
mlx5 interface header to introduce necessary definitions for MGMT PF
and adding a new management PF netdev profile, which will allow the host
side to communicate with the embedded linux on Blue-field devices.
