I have patches from Michael Tsirkin that I am integrating now, which will set the value in the init_attr->cap.max_inline_data returned from the ibv_create_qp() verb. This should be done by tomorrow.

This still needs to be implemented... there will be functions
int ibv_attach_mcast(struct ibv_qp *qp, union ibv_gid *gid, uint16_t lid); int ibv_detach_mcast(struct ibv_qp *qp, union ibv_gid *gid, uint16_t lid);
these should also be done soon.
Thank you for the information. Looking forward to having these features in Gen2.
Thanks, Sayantan.
