pull-request: mac80211-next 2016-06-09

[Johannes Berg]

Hi Dave,

Here's my first set of changes for -next. The only exciting part are the
changes from Michał to integrate FQ/codel into mac80211's software queues
to improve cross-station latency and finally solve much of the latency
issues so many people have spent so much time talking about, but never
actually working on fixing until he did :)

Can I ask you to pull net into net-next, preferably before merging this?
I have a patch that is unsafe without a fix that I submitted through
mac80211 previously (last time, not the pull request a few minutes ago),
and I'd prefer not to have that in our -next trees without the fix. If
you merge net into net-next before this pull request I can fast-forward
mac80211-next to this merge later.

Let me know if there's any problem.

Thanks,
johannes

  mac80211: implement codel on fair queuing flows (2016-06-09 11:45:10 +0200)

----------------------------------------------------------------
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

Thanks! I see you also had pulled net in for other reasons, so I'll
include the hwsim namespace patch in the next pull request :)

I pulled it in because you said that I had to before pulling this one.
