| 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. |

| 11 | * Command formation should use a copy of the structs in mlx5_ifc.h following |
