The RPC/RDMA code had a constant 5-second reconnect backoff, and
always performed it, even when re-establishing a connection to a
server after the RPC layer closed it due to being idle. Make it
an geometric backoff (up to 30 seconds), and don't delay idle
reconnect.

The RPC/RDMA protocol allows clients and servers to avoid RDMA
operations for data which is purely the result of XDR padding.
On the client, automatically insert the necessary padding for
such server replies, and optionally don't marshal such chunks.

An RPC/RDMA client cannot retransmit on an unbroken connection,
doing so violates its flow control with the server.

Configure, detect and use "fastreg" support from IB/iWARP verbs
layer to perform RPC/RDMA memory registration.
Make FRMR the default memreg mode (will fall back if not supported
by the selected RDMA adapter).
This allows full and optimal operation over the cxgb3 adapter, and others.

In order to be able to support setting the timeo and retrans parameters on
a per-mountpoint basis, we move the rpc_timeout structure into the
rpc_clnt.

xprt_disconnect() should really only be called when the transport shutdown
is completed, and it is time to wake up any pending tasks. Rename it to
xprt_disconnect_done() in order to reflect the semantical change.

Support for binary sysctls is being deprecated in 2.6.24. Since there
are no applications using the NFS/RDMA client's binary sysctls, it
makes sense to remove them. The patch below does this while leaving
the /proc/sys interface unchanged.
Please consider this for 2.6.24.

This implements the configuration and building of the core transport
switch implementation of the rpcrdma transport. Stubs are provided for
the rpcrdma protocol handling, and the infiniband/iwarp verbs interface.
These are provided in following patches.
