This patch series supports a matching user space patch set:

	Provider/rxe: Implement extended verbs APIs

Together these implement the following erxtended verbs APIs:
        ibv_query_device_ex
        ibv_create_cq_ex
        ibv_create_qp_ex

They also implement the field parse and set ops in struct ibv_cq and ibv_qp.

Introduce a pair of SW capability bit masks that are exchanged between
the user space provider and the kernel space driver during the
ibv_alloc_context verb to allow the provider and driver to adjust
shared data structures depending on which capabilities are supported.
This is an extensible mechanism to avoid changes to ABI version.
