There’s one big flaw with this: if packets are available for multiple destinations, fq_codel will generally give you a variety pack of packets for each of them. But a wifi TXOP is for a single destination, so only some of the packets would be eligible for the same aggregate frame. So what’s needed is a way for the wifi driver to tell the queue that it wants packets for the *same* destination as it’s transmitting to. > - Once the transmit opportunity has come around, it's a matter of > microseconds (I assume) to pull in a wifi frame's worth of packets from > fq_codel This is hard to guarantee in software in a general-purpose OS. - Jonathan Morton _______________________________________________ Cerowrt-devel mailing list [email protected] https://lists.bufferbloat.net/listinfo/cerowrt-devel
