* The following opcodes are defined:
* VFXPF_TESTLOOP_OPCODE_NOP_ will return no data.
* VFXPF_TESTLOOP_OPCODE_BUSY_ will reply with BUSY response first.
* VFXPF_TESTLOOP_OPCODE_RETRY_ will reply with RETRY response instead.
* VFXPF_TESTLOOP_OPCODE_ECHO_ will return same data as received.
* VFXPF_TESTLOOP_OPCODE_FAIL_ will always fail with error.
