| * 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 | |
| * the Programmers Reference Manual. A open release is available here: | |
| * | |
| * https://network.nvidia.com/files/doc-2020/ethernet-adapters-programming-manual.pdf | |
