That worked, thanks.
> Johannes, this is _evil_:
It's not only _evil_, it's also undocumented. I was just
following include/net/cfg80211.h. There is no kernel-doc in the
comments for "cookie", neither in
[struct cfg80211_ops:]
int (*deauth)(struct wiphy *wiphy, struct net_device *dev,
struct cfg80211_deauth_request *req,
void *cookie);
nor in
void cfg80211_send_deauth(struct net_device *dev, const u8 *buf, size_t len,
void *cookie);
so I automatically assumed that I have to provide the "cookie" I
got in my deauth()-handler to cfg80211_send_deauth().
/me says "I can haz a cookie?"
