Maybe we can simply check retry attrs or even retry data, e.g.: if (attrs[NL80211_ATTR_TID_RETRY_LONG] || attrs[NL80211_ATTR_TID_RETRY_SHORT]) { ... if ((retry_short > 0) || (retry_long > 0)) { ... > + if (!wiphy_ext_feature_isset( > + &rdev->wiphy, > + NL80211_EXT_FEATURE_PER_TID_RETRY_CONFIG)) > + return -EOPNOTSUPP; > + > + if (peer && !wiphy_ext_feature_isset( > + &rdev->wiphy, > + NL80211_EXT_FEATURE_PER_STA_RETRY_CONFIG)) > + return -EOPNOTSUPP; > + > + if (!rdev->ops->set_data_retry_count || > + !rdev->wiphy.max_data_retry_count) > + return -EOPNOTSUPP; > + > + ret = rdev_set_data_retry_count(rdev, dev, peer, tid_no, > + retry_short, retry_long); > + } > + > + return ret; > +} Regards, Sergey
