Ah, I see. This makes sense to me. I ignored the 11r code when I wrote
the code. Now I realized what it is used for (i.e. sme_event_auth). I'm
not sure if it can be done in cfg80211 SME easily, but it doesn't help
for connect API anyway. I'll send V2 according to your suggestion.
Johannes, I think we need a way in cfg80211 to tell connect vs.
auth/assoc. The current capability method (nl80211_send_wiphy) cannot do
this. For example,
if (dev->ops->connect || dev->ops->auth)
NLA_PUT_U32(msg, i, NL80211_CMD_CONNECT);
We need to either make NL80211_CMD_CONNECT only depends on ops->connect
or make NL80211_CMD_AUTH depends on ops->auth. Johannes, which one do
