It behaves like > Linux... sometime. Depending on whether it is a magic TCP port or not. I agree with everything Jeff has stated. Also, I find it ironic that the port abduction is being asked for in order to be "compatible with existing tools" yet in fact this stuff breaks everything. You can't netfilter this traffic, you can't apply qdiscs to it, you can't execut TC actions on them, you can't do segmentation offload on them, you can't look for the usual TCP MIB statistics on the connection, etc. etc. etc. It is broken from every possible angle. -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
