mac80211: allow drivers to set default uAPSD parameters
mac80211 currently sets uAPSD parameters to have VO AC trigger- and delivery-enabled, with maximum service period length. Allow drivers to change these default settings since different uAPSD client implementations may handle errors differently and be able to recover from some errors. Note: some APs may not function correctly if one or all ACs are trigger- and delivery-enabled, see http://thread.gmane.org/gmane.linux.kernel.wireless.general/93577. We retested with this AP and later firmware doesn't have this bug any more. Signed-off-by: Alexander Bondar <alexander.bondar@intel.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
