Code Issues Projects Releases Wiki Activity

For the next cycle, we have the following: 

* the biggest change is Michał's work on integrating FQ/codel
    with the mac80211 internal software queues
  * cfg80211 connect result gets clarified for the
    "no connection at all" case
  * advertisement of per-interface type capabilities, in case
    they differ (which makes a lot of sense for some capabilities)
  * most of the nl80211 & hwsim unprivileged namespace operation
    changes
  * human-readable VHT capabilities in debugfs
  * some other cleanups, like spelling
