NAME
       ibv_set_ece - set ECE options and use them for QP configuration stage.

SYNOPSIS
              #include <infiniband/verbs.h>

              int ibv_set_ece(struct ibv_qp *qp, struct ibv_ece *ece);

DESCRIPTION

       The desired ECE options will be used during various modify QP stages
       based on supported options in relevant QP state.

ARGUMENTS

                  uint32_t vendor_id;
                  uint32_t options;
                  uint32_t comp_mask;
              };

       vendor_id

       value which indicates the failure reason.
