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).

2 Control bits:
[7] - Reserved
[6] - 1b = quiescence acknowledge (OS ready)
[5] - 1b = OS daemon present
[4] - 1b = quiesce request (FRU Control)
[3] - Reserved
[2] - 1b = graceful reboot request (FRU Control)
[1] - 1b = quiescence reached (MMC acknowledge)
[0] - 1b = module hot swap switch opened
Response data
3 Quiesce wait timeout (valid only if OS daemon present = 1)
Settings changed with this command are volatile (in particular quiesce timeout and OS
daemon present). Bits [6:5] are always settable, but once the quiesce request comes they
cannot be cleared until quiescence state is entered and exited.
