Sorry if I was not clear, but I would like to combine #42 and #44
experiments.
Ie making sure that even with BBR on linux-4.3-rc1/rc2 (without FQ
packet qdisc), we can simply tweak TCP Small queue threshold as #42
results would suggest to resolve this bug.
Thanks !

Please do not compare UDP and TCP, this is absolutely useless.

Title:
Poor performance of Atheros QCA6174 802.11ac (rev 32)
Kirill, would it be possible to run again your experiments, but using
bbr congestion control ?
Note that you should use 4.13-rc1 so that following commit is included :
commit 218af599fa635b107cfe10acf3249c4dfe5e4123 ("tcp: internal implementation
for pacing")
lpaa5:~# modprobe tcp_bbr
Thanks to all of you for the tests, sorry for the delay, I have been on
vacation last week.
Yes, the plan is to permanently change TCP stack, since TCP Small queue
being very aggressive is no longer needed when FQ packet scheduler or
BBR congestion module is used for TCP.

Thanks, can you now try :
limit = max(4 * skb->truesize, sk->sk_pacing_rate >> 8);
Then :
limit = max(2 * skb->truesize, sk->sk_pacing_rate >> 7);
Then :
limit = max(4 * skb->truesize, sk->sk_pacing_rate >> 7);

skb_orphan() is not the way to go.
Can someone try the following patch ?
