[PATH v4 0/3] vdpa: support set mac address from vdpa tool

[Cindy Lu]

Add support for setting the MAC address using the VDPA tool.
This feature will allow setting the MAC address using the VDPA tool.
For example, in vdpa_sim_net, the implementation sets the MAC address
to the config space. However, for other drivers, they can implement their
own function, not limited to the config space.

Changelog v2
 - Changed the function name to prevent misunderstanding
 - Added check for blk device
 - Addressed the comments
Changelog v3
 - Split the function of the net device from vdpa_nl_cmd_dev_attr_set_doit
 - Add a lock for the network device's dev_set_attr operation
 - Address the comments
Changelog v4
 - Address the comments
 - Add a lock for the vdap_sim_net device's dev_set_attr operation
