[ofa-general] How can i use the interface "rdma_xx" in linux kernel

[yangdong]

So far, what i see is all about introduction of ib interface in linux
kernel, e.g. Introduction to the InfiniBand Core Software,
Bob Woodruff,Sean Hefty, 2005 Linux Symposium. But in linux kernel there
are also rdma_xxx interface, e.g. rdma_connect, rdma_listen,etc. How can
i use these interface? Please give me a tip.
