[openib-general] [PATCH]proposal for enabling partial ports on HCA

[Shirley Ma]

> One thing that strikes me is to have a single "bit map" (or it's 
equivalent, implemented in say
ib_device). This single "bit map" corresponds to the physical ports. So, 
each of the higher level modules
only references this "bit map" and one does not have mad client "bit map", 
sa client "bit map" and so on 
-is my understanding of your proposal correct?
With multiple "bit maps" isn't there a risk of these not being in sync, 
resulting in hard to detect problems?

There is not a really bitmap there. I just use it to be easily understood. 
The client registration has sequence. Checking resouce dependency is 
needed to start upper client registration on that port.
