Another core difference is that on cerowrt's wireless, I did much more
diffserv classification than what's currently in the kernel mainline
and openwrt.

In particular, one thing you can really 'feel' is that stuff with the
IMM bit set
(notably ssh), gets dumped into the VI queue, and that helps ssh a LOT.

Unfortunately that series of patches was terribly hacky and I still haven't
found a good way to rework them for submittal upstream.

You easily get the same behavior for things like ssh via iptables.
