Merge branch 'devlink-mlx5-add-new-parameters-for-link-management-and-sriov-eswitch-configurations'
Saeed Mahameed says:
====================
devlink, mlx5: Add new parameters for link management and SRIOV/eSwitch configurations [part]
This patch series introduces several devlink parameters improving device
configuration capabilities, link management, and SRIOV/eSwitch, by adding
NV config boot time parameters.
Implement the following parameters:
a) total_vfs Parameter:
-----------------------
Adds support for managing the number of VFs (total_vfs) and enabling
SR-IOV (enable_sriov for mlx5) through devlink. These additions enhance
user control over virtualization features directly from standard kernel
interfaces without relying on additional external tools. total_vfs
functionality is critical for environments that require flexible num VF
configuration.
b) CQE Compression Type:
------------------------
Introduces a new devlink parameter, cqe_compress_type, to configure the
rate of CQE compression based on PCIe bus conditions. This setting
provides a balance between compression efficiency and overall NIC
performance under different traffic loads.
