Hi Anna-

These are bug fixes and add support for RPC-over-RDMA connection
keepalive. The keepalive patches are still waiting for internal
testing resources to confirm they trigger connection loss in the
right circumstances, but my own testing shows they are behaving as
expected and do not introduce instability.
