Subject: [PATCH mlx5-next v1 00/11] Convert mlx5 to use auxiliary bus

From: Leon Romanovsky <leonro@...dia.com>

Changelog:
v1:
 * Renamed _mlx5_rescan_driver to be mlx5_rescan_driver_locked like in
   other parts of the mlx5 driver.
 * Renamed MLX5_INTERFACE_PROTOCOL_VDPA to tbe MLX5_INTERFACE_PROTOCOL_VNET as
   a preparation to coming series from Eli C.
 * Some small naming renames in mlx5_vdpa.
 * Refactored adev index code to make Parav's SF series to apply more easily.
 * Fixed devlink reload bug that caused to lost TCP connection.

--------------------------------------------------------------

Hi,

This patch set converts mlx5 driver to use auxiliary bus [1].

In this series, we are connecting three subsystems (VDPA, netdev and
RDMA) through mlx5_core PCI driver. That driver is responsible to create
proper devices based on supported firmware.

First four patches are preparitions and fixes that were spotted during
code development, rest is the conversion itself.

Thanks
