[OFW][patch] partition - amended

[Slava Strebkov]

Hi Sean,
The application can order to bus driver what PDO to create (dynamically)
by IOCTL.
PnP manager will update the registry hardware key for newly created
device and load the function driver (IPoIB).
What registry update did you mean?

My thoughts:  The suggestion is for the bus driver to read from the
registry.
It can do this when loading.  The IOCTL call is a way to indicate to the
bus
driver that it needs to re-read the registry for possible changes.

The benefit is that you remove the policy for searching for IOU's,
IOC's, etc.
out of the kernel and into userspace.  The bus driver can create PDOs
for known
devices, but when a new device is added, a configuration utility for
that device
is run as part of an installation process on the system that should
control it.
The utility can update the registry, then signal the bus driver to
re-read it.
