If no daemon is announced as present
If no command call announces that a daemon is present, the MMC automatically uses the
default timeout time 0 (endless wait) during the Hot Swap process. But if the timeout time
was set to a value 1…255 this time will be used in any case while waiting for the sleep state
(signal).

Byte Data Field
1 Control bits:
[7] - 1b = set quiesce wait timeout
[6] - 1b = quiescence acknowledge (OS ready)
[5] - 1b = OS daemon present
[4:0] Reserved
Request data
2 Quiesce wait timeout [sec]
a) An OS daemon is present (refer to bits above):
This is the maximum time from the moment on that the
MMC receives FRU Control (Quiesce) request until
it sends back the appropriate Module Hot Swap event
message.
b) No OS daemon is present (refer to bits above):
This is the maximum time from the moment on that the
MMC receives FRU Control (Quiesce) request until
it sends back the appropriate Module Hot Swap event
message.
If sleep state is recognized before timeout then the
Module Hot Swap event message will be sent
immediately. If the time is set to 0 (default after reset)
then the Module Hot Swap event message will only be
sent after recognition of sleep state (signal).
