[Anatoly Greenblatt]

Hi All,

The hardware id of default (primary) partition does not change. The
iba\ipoibp used to id only new partitions, other than default. It is
done to ease the recognition of partitions in device manager / network
connections. Otherwise the user had to look for device instance id to
figure out if the network connection is on primary (default) or new
partition.
 
And I agree with Stan that uninstall should remove iba\ipoibp devices
(if exist)

Regards,
Anatoly.

I don't understand why the hardware ID would change based on partition.
The device didn't change, the driver didn't change...  I can understand
adding the partition key to the unique ID, but not to the HW ID.
Keeping the default partition key out of the unique ID also means that
someone can upgrade drivers without losing the settings for the NIC
(otherwise it shows up as a new NIC).  So I'd like to see IBA\IPoIB
remain the HW ID for at a minimum the default partition (primary).
