[ewg] RDMA CM: private_data_len

[Yann Droneaud]

Hi,

On a client, rdma_connect() returns -1 and set errno EINVAL if 
struct rdma_conn_param->private_data_len is set to something higher than
56 bytes.

But on a server, using rdma_accept() with struct
rdma_conn_param->private_data_len is set to 64 (for example) didn't
return any error. 

What is the maximum data size that can be exchanged between peers at
connection time, and where to find its definition (at compile time or at
runtime) ?

Regards.
