Hi Thomas

Thank you for your reply.

Could you please let me know how can I verify these queues on a mesh
router? (I am using TPLink router with Ath9k chipset).

Also, the TXQ parameters can only be set if device is in AP or P2P
mode. Do you have any idea why this restriction is in place?

https://github.com/torvalds/linux/blob/master/net/wireless/nl80211.c

static int nl80211_set_wiphy(struct sk_buff *skb, struct genl_info *info)
{

           if (info->attrs[NL80211_ATTR_WIPHY_TXQ_PARAMS]) {
           ....
                   if (netdev->ieee80211_ptr->iftype != NL80211_IFTYPE_AP &&
                       netdev->ieee80211_ptr->iftype != NL80211_IFTYPE_P2P_GO)
                                 return -EINVAL;
           ...
}

Best Regards
Phani
