#242 IPoIB: a bug about port down and active

[penglonggen]

When loading IPoIB module(SM is running),the AL pnp
events series are: port add >> port active. After
configured IP address,if you unplug the cable,the net
device will be unregistered,but IPoIB module is still exist
in system. In this case,plug the cable again,the host OS
will be dead.
It seens when the port down (unpluged the
cable),IPoIB have not free the port's resource
properly.When pluged the cable again,IPoIB can not
handle the port active event properly.
I can not find any IPoIB traces in /var/log/messages
after OS restart.
