Subject: [PATCH net-next V2 5/8] net/mlx5: Set driver version infrastructure

Add driver_version capability bit is enabled, and set driver
version command in mlx5_ifc firmware header.  The only purpose
of this command is to store a driver version/OS string in FW
to be reported and displayed in various management systems,
such as IPMI/BMC.
