This patch series adds support for native IB addressing to the
rdma cm. The full patch series is available from:

The rdma cm is the only widely usable interface for establishing
communication

The rdma_cm only allows setting reuseaddr if the corresponding
rdma_cm_id is in the idle state. Allow setting this value in
other states. This brings the behavior more inline with
sockets.

The AF_IB uses a 64-bit service id (SID), which the
user can control through the use of a mask. The rdma_cm
will assign values to the unmasked portions of the SID
based on the selected port space and port number.
Because the IB spec divides the SID range

cma_resolve_loopback is called after an rdma_cm_id has been

Allow the user to specify the remote address using AF_IB format.
When AF_IB is used, the remote address simply needs to be recorded,
and no resolution using ARP is done. The local address may still
need to be matched with a local IB device.

Currently, DFSSSP maps the src/dest paths statically to certain VLs.
Especially for deadlock-free topologies this can result in an
unfair balancing. Some VLs within one link might be overused,
which results in slower bandwidth for some src/dest pairs.
The fix changes the VL assignment in two
