 * These are definitions for the command interface for mlx5 HW. mlx5 FW has a
 * User Context mechanism which allows the FW to understand a security scope.
 * FWCTL binds each FD to a FW user context and then places the User Context ID
 * (UID) in each command header. The created User Context has a capability set
 * that is appropriate for FWCTL's security model.
 *
 * Command formation should use a copy of the structs in mlx5_ifc.h following
