2009-08-23RDS: Track transports via an array, not a listAndy Grover
Now that transports can be loaded in arbitrary order, it is important for rds_trans_get_preferred() to look for them in a particular order, instead of walking the list until it finds a transport that works for a given address. Now, each transport registers for a specific transport slot, and these are ordered so that preferred transports come first, and then if they are not loaded, other transports are queried.

2009-08-23RDS: Export symbols from core RDSAndy Grover
Now that rdma and tcp transports will be modularized, we need to export a number of functions so they can call them. Signed-off-by: Andy Grover <andy.grover@oracle.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-02-26RDS: Transport codeAndy Grover
RDS supports multiple transports. While this initial submission only supports Infiniband transport, this abstraction allows others to be added. We're working on an iWARP transport, and also see UDP over DCB as another possibility. This code handles transport registration.
