[openib-general] rdma_conn_param private datalen

[Michael S. Tsirkin]

Sean, its a bit unclear what do the private_data/private_data_len
fields in rdma_conn_param do.

It seems that the user has to set these to point to a buffer with
including full private data, including the fields CMA fields, which
is OK I guess but a bit counter-intuitive, so it might be
a good ide to document this.
