Subject: [PATCH net-next 00/14] net/mlx5: qos: Refactor esw qos to support new features

Hi,

This patch series by Cosmin and Carolina prepares the mlx5 qos infra for
the upcoming feature of cross E-Switch scheduling.

Noop cleanups:
net/mlx5: qos: Flesh out element_attributes in mlx5_ifc.h
net/mlx5: qos: Rename vport 'tsar' into 'sched_elem'.
net/mlx5: qos: Consistently name vport vars as 'vport'
net/mlx5: qos: Refactor and document bw_share calculation
net/mlx5: qos: Rename rate group 'list' as 'parent_entry'

Refactor the code with the goal of moving groups out of E-Switches:
net/mlx5: qos: Maintain rate group vport members in a list
net/mlx5: qos: Always create group0
net/mlx5: qos: Drop 'esw' param from vport qos functions
net/mlx5: qos: Store the eswitch in a mlx5_esw_rate_group

Move groups from an E-Switch into an mlx5_qos_domain:
net/mlx5: qos: Store rate groups in a qos domain

Refactor locking to use a new mutex in the qos domain:
net/mlx5: qos: Refactor locking to a qos domain mutex

In follow-up patchsets, we'll allow qos domains to be shared
between E-Switches of the same NIC.

The two top patches are simple enhancements.

Series generated against:
commit f95b4725e796 ("net: phy: mxl-gpy: add missing support for TRIGGER_NETDEV_LINK_10")

Regards,
Tariq
