Do we really need this additional flag to indicate retry data ?
Maybe we can simply check retry attrs or even retry data, e.g.:
Yes, because this implementation gives provision to set default retry
count for TID traffic type for a station.
Since we use single NL command for all TID configurations, this flag
will be useful to notify the driver about
retry TID configuration change.
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;
+}
