Of course some of these routers setup custom qdiscs so they wouldn't be affected, but there may be ones out there relying on the default pfifo. Now I understand that having a pfifo is an anathema to multi-queue TX by definition. However, even if we couldn't preserve the full semantics by default, if we could at least preserve the ordering within each queue it would still be a plus.
