ext_umad ("extended umad") provides an interface and utilities for
handling planarized HCAs. The planarized HCAs appear as 2 separate
devices on umad_get_cas output, and the ext_umad interface allows to
group the devices together, and find matching devices.

In planarized fabrics, all SMPs must be sent by direct route. convert_portid_to_dr converts a portid object to direct route. Signed-off-by: Amir Nir <anir@nvidia.com>

…brics. ibportstate now checks if source CA is a planarized CA, and if so, uses direct route only. if the destination's direct route isn't given as argument, ibportstate will perform a fabric discovery to determine the direct route to the destination. Signed-off-by: Amir Nir <anir@nvidia.com>

Added ext_umad files with utilities to handle XDR devices, where a single CA has 2 umad devices.
Adapted ibportstate to send SMP only in direct route, as required in planarized fabrics (LID routed SMPs aren't valid in planarized fabrics).
