A patch for this would be accepted.  I should note that other modules, such as 
the CM, follow this same error recovery.  If an error occurs trying to 
initialize any of the ports, the entire device is not used by that module.

Ipoib appears to handle each port separately, however, so that a failure on one 
port does not mark the others as invalid.  Roland should know for certain, but 
at least that's the way the code looks to me.
