Issue with wlan TX queues

[wizath]

Hi,

I'm trying to revisit the wfb-ng after a while. Last year I've got WiFi Halow with nrc7292 working for simple UDP exchange using netcat. I wanted to use the most recent wersion of wfb-ng, but encountered issue while sending packets:

[  +0.197258] af_packet: wlan0 selects TX queue 2, but real number of TX queues is 1
[  +0.186231] af_packet: wlan0 selects TX queue 2, but real number of TX queues is 1
[  +0.193818] af_packet: wlan0 selects TX queue 2, but real number of TX queues is 1
[  +0.175842] af_packet: wlan0 selects TX queue 2, but real number of TX queues is 1
[  +0.186105] af_packet: wlan0 selects TX queue 2, but real number of TX queues is 1
[  +0.180408] af_packet: wlan0 selects TX queue 2, but real number of TX queues is 1
[  +0.000112] af_packet: wlan0 selects TX queue 2, but real number of TX queues is 1

Can this is related to the wfb-ng itself or the wireless chip driver? Anyone has any idea how to fix this issue ?

Do you use standalone wfb_rx/tx programs or full wfb-ng version?

I've tried to use wfb-ng at first, then after looking at Troubleshooting guide used tx_standalone.sh and rx_standalone.sh. In both cases got the same result

And last time I used the wfb_rx/wfb_tx combo, with parameters taken directly from wfb-server. Also checked the wlan0 interface

11: wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP mode DEFAULT group default qlen 2000
    link/ieee802.11/radiotap 84:25:3f:9c:09:e7 brd ff:ff:ff:ff:ff:ff promiscuity 0 minmtu 256 maxmtu 2304 addrgenmode none. numtxqueues 1 numrxqueues 1 gso_max_size 65536 gso_max_segs 65535

There is one tx queue and one rx queue, but I can't find reference in code where it tries to use another queue

Try to add -Q to the wfb_tx args

Thanks alot, I'm no longer getting these warnings! continuing testing
