Some more work for 4.7, notably:

* completion and fixups of nla_put_64_64bit() work
  * remove a/b/g/n from wext nickname to avoid confusion

====================
Some more work for 4.7, notably:
 * completion and fixups of nla_put_64_64bit() work
 * remove a/b/g/n from wext nickname to avoid confusion
   with 11ac (which wouldn't even fit fully there due to
   string length restrictions)

along with some other minor changes/cleanups.
