I am not convinced. First only MAD resouce not all resouces allocated to
that device gets cleanup. (Some resources are still allocated for all
I was only referring to the MAD code.
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.
This is an error handling issue that can be fixed. Although, I don't think that
it's necessarily worth doing, since errors should be very rare.
The error wrt to ipoib hanging the kernel, if an earlier error should occur,
needs to be fixed however. The problem could be in the MAD layer, SA code, or
ipoib itself.
