[PATCH wireless-next v3 7/7] wifi: mac80211_hwsim: claim support for Control Integrity Protocol

[Benjamin Berg]

From: Benjamin Berg <benjamin.berg at intel.com>

The mac80211_hwsim driver never actually generates control frames. As
such, it can simply claim the Control Integrity protocol (CIP).

Signed-off-by: Benjamin Berg <benjamin.berg at intel.com>

v3:
- Enable CIP for more interface types (requires extended capabilities)
