[PATCH 12/20 v2] rdma/cm: Define new RDMA port space specific for IB

[PATCH 12/20 v2] rdma/cm: Define new RDMA port space specific for IB

[Hefty, Sean]

Add RDMA_PS_IB.  XRC QP types will use the IB port space
when operating over the RDMA CM.  For the 'IP protocol'
field value, we select 0x3F, which is listed as being for
'any local network'.
