I realize that the code assume IPv4 in several places, but that should be a 
temporary limitation.  I just haven't had time to add in IPv6 support yet.

My original plan was that the sockaddr's should eventually be cast to the 
correct structure based on the sa_family type.  But I don't think that this will 
be sufficient to handle all cases.  Adding a pointer to set of functions, or 
adding a set of function pointers to the rdma_cm_id may be the correct solution 
when IPv6 is fully supported.
