Set the NL80211_EXT_FEATURE_DEL_IBSS_STA if the interface support IBSS
mode, so that stations can be reset from user space.
mac80211 already deletes stations by itself, so mac80211 drivers must
already support this.
This has been successfully tested with ath9k.

Hi Nicolas,
I took these patches for a thorough spin offshore (combined with your
quick wpa_sup change)
Quick test setup overview:
- Device mounted on top of a vessel, sailing around in windfarms.
- Lots of turbines are equiped with 4x 90deg sectors
- 802.11n HT40 2x2 custom mesh over IBSS, using Dynack
- As the vessel moves around, IBSS links are continuously dropped and
re-added throughout the field
- Output of my app, fyi: https://pastebin.com/raw/vtZSwHC9
I've made 2 identical builds, one containing your patches and one without.
When your patches are used:
--> On devices with multiple radio's, all radio's went deaf within a few
minutes without any notice in logs.
--> Only a reboot solved the issue but everything goes deaf again within
a few minutes. (after dropping/adding some links)
Any idea?
Thanks,
Koen
