Subject: Query on iw command to set txq params

Hi All

I am trying to apply the path mentioned below to set txq params using
iw command.

http://www.spinics.net/lists/linux-wireless/msg42585.html

But I am getting below error.

root@teste-VirtualBox:~/old_iw/iw-0.9.17# ./iw list | grep Wiphy
Wiphy mn00s05
Wiphy mn00s04
Wiphy mn00s03
Wiphy mn00s02

I am using mininet wifi to create topology with 4 APs.

Could someone suggest how to proceed on this?

Why don't you just set it in hostapd?

The patch is wrong (now?), it needs to use the *netdev* not just the
wiphy.

Hi Johannes Berg

I am trying to change the parameters for wireless mesh backbone
router. Is hostapd used for AP type configuration?

Hi Johannes Berg

Thank you for your reply.

Could you please point me to any reference implementation I can check
to make the correct modification?
