The deauth message comes from:
int ieee80211_sta_deauthenticate(struct ieee80211_sub_if_data *sdata,
u16 reason)
{
printk(KERN_DEBUG "%s: deauthenticating by local choice
(reason=%d)\n",
sdata->dev->name, reason);
which is called from the close/down function for mac80211 interfaces:
static int ieee80211_stop(struct net_device *dev)
{
...
if (sdata->vif.type == NL80211_IFTYPE_STATION) {
if (sdata->u.mgd.state != IEEE80211_STA_MLME_DISABLED)
ieee80211_sta_deauthenticate(sdata,
WLAN_REASON_DEAUTH_LEAVING);
}
WLAN_REASON_DEAUTH_LEAVING is defined as 3.
It can also be called in response to a command sent over netlink.

What about wpa_gui?

If at first you don't succeed, you're doing about average.
