[PATCH v2] vdpa/mlx5: Enable user to add/delete vdpa device

From: Eli Cohen <hidden>
Date: 2021-02-18 08:50:03

Allow to control vdpa device creation and destruction using the vdpa
management tool.

Examples:
1. List the management devices
$ vdpa mgmtdev show
pci/0000:3b:00.1:
  supported_classes net

2. Create vdpa instance
$ vdpa dev add mgmtdev pci/0000:3b:00.1 name vdpa0

3. Show vdpa devices
$ vdpa dev show
vdpa0: type network mgmtdev pci/0000:3b:00.1 vendor_id 5555 max_vqs 16 \
max_vq_size 256
