     5	 * These are definitions for the command interface for mlx5 HW. mlx5 FW has a
     6	 * User Context mechanism which allows the FW to understand a security scope.
     7	 * FWCTL binds each FD to a FW user context and then places the User Context ID
     8	 * (UID) in each command header. The created User Context has a capability set
     9	 * that is appropriate for FWCTL's security model.
    10	 *
    11	 * Command formation should use a copy of the structs in mlx5_ifc.h following
    12	 * the Programmers Reference Manual. A open release is available here:
