+Add auto parameter to set distance command in order to enable ACK timeout
+estimation algorithm (dynack). Dynack is automatically disabled setting valid
+value for coverage class. Currently dynack is supported just by ath9k
+
+This patch is based on "configure dynack through mac80211/cfg80211 stack"
