The best way to implement this is to leverage all the checksum offload work people did for virtualization. Forward the checksum offload status through the RC connection and recover it on the other side. Then the far side stack will know it is dealing with a partial checksum packet and will properly regenerate the checksum if it re-transmits. ie doing it this way doesn't totally break the netstack :) Jason -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
