mac80211: update to backports-4.14-rc2"

Let's see how this will play out.

What does WPS has to do with ieee80211w?
I think the problem is the newer version of hostapd

Nothing directly. But the CONFIG_WPS did set the NEED_SHA256 dependency in src/hostapd/Makefile (which CONFIG_IEEE80211W needs). Without CONFIG_WPS, this is no longer the case. But other options set it as well,
with any luck something else in the hostapd-full.config needs it too and sets it.

But If this error can really be traced to the the backports-4.14-rc2 patch, you could also try if installing the kmod-cmac module helps. (Note: the module will need to be loaded / (or you reboot the router). I know that mac80211 can request missing cipher modules at runtime and that this is working on a debian system with udev / systemd. But I haven't
verified that procd does it too ).

But in my commit i removed CONFIG_WPS2, not CONFIG_WPS...

I'm going to test the older hostapd version

Ok, just tested with older version of hostapd (2016-12-19) and it's NOT working.
So the problem may be really related to backports-4.14-rc2.

Felix has posted RFT on the mailing-list.

For me it's working again after this commit

   0 dBm (   1 mW)
   1 dBm (   1 mW)
   2 dBm (   1 mW)
*  3 dBm (   1 mW)
   4 dBm (   2 mW)
