This one defines a framework for getting communication resources, and creating interface. An implementation over IB/RC is also included.
Hardware resources are identified by a string, e.g "mlx4_0:1", or "memory". The returned list is of all supported combinations of transports and resources.
The subnet address field is intended to provide "proximity"/"connectivity" information to upper level/user. It could be IB subnet prefix, or an IPv4/v6 subnet prefix, or in case of shared memory - unique host ID. The rule is, if you have an interface created on one resource, it could talk to any interface created on a remote resource, provided they have the same subnet address. This of course does not deal with cluster mis-configuration issues.

Do we want to change 64 to:
#define UCT_MAX_NAME_LEN (64)

[yosefe]

ok

The above error seems to be installation problem.
