If we send immediately then we would need to check on each packet if the multicast creation has been completed? Also broadcast could cause a unecessary reception event on the NICs of machines that have no interest in this traffic. We would like to keep irrelevant traffic off the fabric as much as possible. An a reception event that requires traffic to be thrown out will cause jitter in the processing of inbound traffic that we also would like to avoid. -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
