+ * WLAN_LINK_STA_PARAMS_PRESENT
+ * WLAN_EHT_CAPABILITY_PRESENT
+ *
+ * To deterministically identify where EHT fields are present (whether in
+ * link_sta_params or station_parameters), enable either
+ * WLAN_LINK_STA_PARAMS_PRESENT or WLAN_EHT_CAPABILITY_PRESENT but not both.
+ *
+ * Incase EHT fields are present in link_sta_parameters only define
+ * WLAN_LINK_STA_PARAMS_PRESENT flag.
+ *
+ * If WLAN_LINK_STA_PARAMS_PRESENT is not defined, then EHT cap can be present
+ * in station_parameters structure, in such case WLAN_EHT_CAPABILITY_PRESENT
+ * flag will be defined.
+ *
+ * If both flags are not enabled then kernel is not EHT capable.

+ * 577e5b8 wifi: cfg80211: add API to add/modify/remove a link station
+ * b95eb7f wifi: cfg80211/mac80211: separate link params from station params
