See the thread at https://mail.openvswitch.org/pipermail/ovs-dev/2017-July/334866.html At least in ath9k the idea is to map the skb-priority directly to the queues according to 802.1d. Since ovs does this strange/undocumented offset of 0x1 I ended up going a different path. I ended up using something along the line of actions=load:1->NXM_NX_PKT_MARK[31],move:nw_tos[5..7]->NXM_NX_PKT_MARK[0..2] And patching ath9k to map these skb-marks to the queues according to my needs.

[ovs-discuss] QoS Queues on wireless interfaces
Hi all, I tried configuring queues with OpenFlow on ethernet interfaces and it worked just fine. However if I set a specific queue on a flow with the set_queue action that outputs the packet to a wireless interface, it somehow is ignored and the default queue 0 is taken. I can set a certain bandwith on queue 0 and therby limit the bandwith however this is not sufficient for my use case. I've run the following commands: 1. Create the QoS and Queues on wireless interface wlan0 ovs-vsctl -- set port wlan0 qos=@newqos -- --id=@newqos create qos type=linux-htb queues:1=@newqueue queues:2=@newqueue2 -- --id=@newqueue create queue other-config:min-rate=300 other-config:max-rate=300 -- --id=@newqueue2 create queue other-config:min-rate=800 other-config:max-rate=800 2. Check the Queues have been created ovs-ofctl queue-get-config ovsbr wlan0 -O OpenFlow13 3. Create a flow that uses Queue 1 for HTTPS traffic ovs-ofctl add-flow ovsbr priority=1,dl_type=0x800,nw_proto=6,tp_src=443,in_port="eth0.2",actions=set_queue:1,output:"wlan0" -O OpenFlow13 4. Check the flow has been created and packets are processed by it ovs-ofctl dump-flows ovsbr -O OpenFlow13 5. Check if traffic is going through Queue 1 (unfortunately not) ovs-ofctl queue-stats ovsbr -O OpenFlow13 So my questions are: 1. Is it possible to have multiple queues on a wireless interface that are managed by a set of flows? 2. What do I have to do to make it work? I found this thread which seems to be related to the issue as well however I do not quite get it: https://mail.openvswitch.org/pipermail/ovs-discuss/2013-August/030714.html Any help is highly appreciated.
