[ofw] [COMMITS] 3121, 3122 - IOC poll on demand.

[Smith, Stan]

Set IOC poll on demand (IOC rescan in batches instead of continuous intervals or not at all) as the default behavior.
White-space clean up - previous pretty print invocations broke up some lines when they comfortably could exist as a single line; collapse to one.

Message:
[CORE-AL+BUS] IOC poll on demand.
g_ioc_poll_interval = 1;
/* 0 == no IOC polling,
 * 1 == IOC poll on demand (IB_PNP_SM_CHANGE, IB_PNP_PORT_ACTIVE,
 *         QUERY_DEVICE_RELATIONS for device 'IB Bus'); 1 batch of IOC rescans
 * > 1 == poll interval in millisecond units.
 */
Poll on demand is implemented as a batch(IOC_RESWEEPS) of IOC rescans with IOC_RESWEEP_WAIT between rescan (see al_ioc_pnp.c).
Batching was the least complicated approach to resolve the issue of continuous IOC polling, as IBAL/cl_pnp() was not really designed to handle PENDING IRPs.
A device rescan (devmgmt.msc) is required in order for diskmgmt.msc to see new SRP targets when demand polling.
