[openib-general] What is the correct method of determining the number of ports

[Kevin Reilly]

Thanks you Roland and Shirley for your responses!!

Roland,  Do you know other things that are missing that you can rattle off
the top of your head?
Else we keep looking for what we need then ask questions if we don't find
them.

Unfortunately there's not a good way at the moment.  I still need to
implement ibv_query_device() for userspace.

Thanks for reminding me -- I should be able to get to it this week.
