I have some hope that the skb->xmit_more API could be used to make
aggregating packets in wifi on an AP saner. (my vision for it was that
the overlying qdisc would set xmit_more while it still had packets
queued up for a given station and then stop and switch to the next.
But the rest of the infrastructure ended up pretty closely tied to
Jesper just wrote a nice piece about it also.
It was nice to fool around at 10GigE for a while! And netperf-wrapper
scales to this speed also! :wow:
I do worry that once sch_fq and fq_codel support is added that there
will be side effects. I would really like - now that there are al
these people profiling things at this level to see profiles including
