I'm trying to come up with a more acceptable patch to the problem discussed a few years
ago:

The patch below appears to work as expected. In pktgen, you just have to set
the QoS to whatever value matches the queue you need.
This seem reasonable?
Why do you adjust the queue mapping instead of the skb priority? In that
other thread you mentioned that pktgen should be able to control the
queue, yet here you're taking queue control away from it for tx on mac80211.
I was having trouble getting it to work, but I was trying it at
a different place in the code when I was hacking on it...
Do you think I'd just need to adjust skb->priority in the
same spot in the code, or is there more to it?
I think that could work.

Before I go work on this, does anyone have any preference over
whether pktgen packets should obey the QoS or the xmit-queue?
Currently, the kernel is effectively broken, and has been for years,
so probably no one has ever used pktgen with wifi devices.
As it turns out, mapping QoS appears to work best for my own needs,
but I can also try using the skb->priority as Felix suggests.
If no one cares, then I'd prefer to stick with the QoS method I posted
recently, and ignore the xmit-queue that pktgen might select.
Thanks,
Ben
