====================
mlx5-next auxbus support

This pull request is targeting net-next and rdma-next branches.

This series provides mlx5 support for auxiliary bus devices.

It starts with a merge commit of tag 'auxbus-5.11-rc1' from
gregkh/driver-core into mlx5-next, then the mlx5 patches that will convert
mlx5 ulp devices (netdev, rdma, vdpa) to use the proper auxbus
infrastructure instead of the internal mlx5 device and interface management
implementation, which Leon is deleting at the end of this patchset.
