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.
For most users, this is user-defined private data exchanged as part of the
connection. Private_data points to a buffer of size private_data_len. The user
does not include any CMA fields, or space for any CMA specific fields, so
private_data behaves like one would expect.
For SDP, the private_data points to the SDP hello header. This is necessary
because of how the hello header is defined, with the location of the
source/destination address coming after SDP specific data.
