[openib-general] problems on device/ports initialization

[Shirley Ma]

> If the MAD code encounters an issue initializing a device,  it will 
cleanup all resources allocated to that device.  The error handling is per 
device, rather than per port.

I am not convinced. First only MAD resouce not all resouces allocated to 
that device gets cleanup. (Some resources are still allocated for all 
ports, and if you continue loading ib_ipoib modules, you can see the ib 
interface with no QP1, but configuring the interface will fail, and hung 
in the kernel.)
Second, the port usability(QP1 & QP0 have both have been created 
successfully) depends on other port is not a good design.
