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 BQL....)
Jesper just wrote a nice piece about it also. http://netoptimizer.blogspot.com/2014/10/unlocked-10gbps-tx-wirespeed-smallest.html 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 those qdiscs. /me goes grumbling back to thinking about wifi.
