+ * @NL80211_ATTR_TID: a TID value (u8 attribute)
+ * @NL80211_ATTR_TID_RETRY_CONFIG: Data frame retry count should be
+ *	applied with the value passed through %NL80211_ATTR_RETRY_LONG
+ *	and/or %NL80211_ATTR_RETRY_SHORT. This configuration is  per-TID,
+ *	TID is specified with %NL80211_ATTR_TID. If the peer MAC address
+ *	is passed in %NL80211_ATTR_MAC, the retry configuration is applied
+ *	to the data frame for the tid to that connected station.
+ *	This attribute will be useful to notfiy the driver to apply default
+ *	retry values for the connected station (%NL80211_ATTR_MAC), when the
+ *	command received without %NL80211_ATTR_RETRY_LONG and/or
+ *	%NL80211_ATTR_RETRY_SHORT.
+ *	Station specific retry configuration is valid only for STA's
+ *	current connection. i.e. the configuration will be reset to default when
+ *	the station connects back after disconnection/roaming.
+ *	when user-space does not include %NL80211_ATTR_MAC, this configuration
+ *	should be treated as per-netdev configuration. This configuration will
+ *	be cleared when the interface goes down and on the disconnection from a
+ *	BSS. When retry count has never been configured using this command, the
+ *	other available radio level retry configuration
+ *	(%NL80211_ATTR_WIPHY_RETRY_SHORT and %NL80211_ATTR_WIPHY_RETRY_LONG)
+ *	should be used. Driver supporting this feature should advertise
+ *	NL80211_EXT_FEATURE_PER_TID_RETRY_CONFIG and supporting per station
+ *	retry count configuration should advertise
+ *	NL80211_EXT_FEATURE_PER_STA_RETRY_CONFIG.
+ * @NL80211_ATTR_TID_RETRY_SHORT: Number of retries used with data frame
+ *	transmission, user-space sets this configuration in
+ *	&NL80211_CMD_SET_TID_CONFIG. Its type is u8, min value is 1 and
+ *	the max value should be advertised by the driver through
+ *	max_data_retry_count. when this attribute is not present, the driver
+ *	would use the default configuration.
+ * @NL80211_ATTR_TID_RETRY_LONG: Number of retries used with data frame
+ *	transmission, user-space sets this configuration in
+ *	&NL80211_CMD_SET_TID_CONFIG. Its type is u8, min value is 1 and
+ *	the max value should be advertised by the driver through
+ *	max_data_retry_count. when this attribute is not present, the driver
