I would like to support SOCK_DGRAM/UDP, and I've had some discussions on what may be the best way to support it. If I had to predict, at some point I expect it to be supported. The main difficulty lies in address resolution. A LOT of non-trivial protocol ends up needing to be hidden under a simple sendto() call. -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
