[openib-general] [RFC] [PATCH 3/7] rdma_cm 2.6.20: remove specifying qp_type when connecting

[Sean Hefty]

Ideally, there should be a 1:1 correspondence between the qp_type for
a connection and the port space associated with an rdma_cm_id.  Remove
the qp_type from the rdma_cm interface.

This is a new patch, and is not part of svn.  The qp_type isn't needed
given the port space type, and removal make the userspace interface
a little cleaner.
