The problem is that we have to allocate the receive buffer before we know how big the packet we're going to receive is. Anyway, see my latest patch. I'm pretty sure it should work -- and I hope the performance is reasonable. Your approach of hacking the max mtu avoids the fragmented skb completely, whereas I'm just making sure the TCP/IP headers are in the linear part. - R. -- 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
