Code Issues Projects Releases Wiki Activity

First batch of iwlwifi patches intended for v5.1 

* Support for Target Wakeup Time (TWT) -- a feature that allows the AP
   to specify when individual stations can access the medium;
 * Support for mac80211 AMSDU handling;
 * Debugging infrastructure work;
 * Preparations for improvements in the device selection code;
 * Some new PCI IDs;
 * Some updates in the documentation;
 * A bunch of fixes for issues found with static analyzers;
 * A couple of janitorial fixes from the community;
 * Some fixes in P2P;
 * Other cleanups and small fixes;
