cfg80211: enable dynack through nl80211
Enable ACK timeout estimation algorithm (dynack) using mac80211 set_coverage_class API. Dynack is activated passing coverage class equals to -1 to lower drivers and it is automatically disabled setting valid value for coverage class. Define NL80211_ATTR_WIPHY_DYN_ACK flag attribute to enable dynack from userspace. In order to activate dynack NL80211_FEATURE_ACKTO_ESTIMATION feature flag must be set by lower drivers to indicate dynack capability.
