Subject: [PATCH v3 iproute2-next 0/8] cm_id, cq, mr, and pd resource tracking

Hello,

This series enhances the iproute2 rdma tool to include dumping of
connection manager id (cm_id), completion queue (cq), memory region (mr),
and protection domain (pd) rdma resources.  It is the user-space part
of the kernel resource tracking series merged into rdma-next for 4.17 [1].

Changes since v2:
- pull in rdma-core include/rdma/rdma_cma.h
- update the new local rdma/include/uapi/rdma/rdma_netlink.h
- 80 column reformat
- add reviewed-by tags

Changes since v1/RFC:
- removed RFC tag
- initialize rd properly to avoid passing a garbage port number
- revert accidental change to qp_valid_filters 
- removed cm_id dev/network/transport types
- cm_id ip addrs now passed up as __kernel_sockaddr_storage
- cm_id ip address ports printed as "address:port" strings
- only parse/display memory keys and iova if available
- filter on "users" for cqs and pds
- fixed memory leaks 
- removed PD_FLAGS attribute
- filter on "mrlen" for mrs
- filter on "poll-ctx" for cqs
- don't require addrs or qp_type for parsing cm_ids
- only filter optional attrs if they are present
- remove PGSIZE MR attr to match kernel
