How about providing some way for the admin to see current and maximum 
memory usage that ipoib could consume based on the current QP and RQ 
settings?

You're using the memory limit to restrict the number of QPs to less than 
what the user requested.  It could instead have been used to restrict 
the size of the receive queue, or both.  Having the extra parameter can 
be confusing.  Consider an admin increasing the RQ size only to find 
that they end up with fewer QPs.
