int rdma_get_remote_ece(struct rdma_cm_id *id, struct ibv_ece *ece);


rdma_get_remote_ece() get ECE parameters as were received from the communication peer.

This function is suppose to be used by the users of external QPs. The call needs to be performed before replying to the peer and needed to allow for the passive side to know ECE options of other side.

Being used by external QP and RDMA_CM doesn’t manage that QP, the peer needs to call to libibverbs API by itself.

Usual flow for the passive side will be:



RDMA communication identifier.


ECE struct to be filled.

rdma_get_remote_ece() returns 0 on success, or -1 on error. If an error occurs, errno will be set to indicate the failure reason.
