cfg80211 sme warning __cfg80211_disconnected

["Luis R. Rodriguez" <mcgrof@gmail.com>]

After a while of being connected (hours) with ath9k as of
wireless-testing from yesterday, I got today this warning repeating in
a loop. The associated message would come up, and then after a few
minutes of ping'ing with no response from the default gw I hit the
warning. This repeats over and over. If I unload ath9k and load it it
gets cured.

This is against a Cisco AP at the office at ATHR in very busy
environment, the AP is a legacy AP (no 802.11n).

And here I hit the warning again.

The warning comes from this chunk:

                for (i = 0; i < MAX_AUTH_BSSES; i++) {
                        if (!wdev->auth_bsses[i])
                                continue;
                        bssid = wdev->auth_bsses[i]->pub.bssid;
                        ret = __cfg80211_mlme_deauth(rdev, dev, bssid, NULL, 0,
                                                WLAN_REASON_DEAUTH_LEAVING);
                        WARN(ret, "deauth failed: %d\n", ret);
                }

I'm using the distro Network Manager but git wpa_supplicant as of a
few weeks ago.
