Not sure if anyone wants/needs that though.
Wouldn't it be possible to implement something like this as a qdisc
on top of
mq that makes use of the current tx rate per station to distribute
the airtime
equitably?
Of course this would require the qdisc to know the tx rate a priori
but for
mac80211 drivers we could just use last_tx_rate as an estimate ...

Maybe someone will make something like "tfifo" in future :)
And when clients are connected, each have his own queue.
then, for example qdisc add dev wlan0 parent 1:10 handle 10 tfifo limit
100ms
If packet are older than 100ms will be dropped, or new packets are not
added, if
there is packet older than 100ms are not sent yet.
I am not sure that bandwidth will be distributed fairly, it is
different question,
probably each queue should have some "limited chunk of time" to send
data.
And again, 802.11a/b/g at least are half-duplex and CSMA, and without
polling/TDMA or CTS/RTS tricks
it will be complicated to give guaranteed chunks of time.
P.S. That's just a dream :)
