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.

Thanks,
