|
| 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:
