no reassociateing with rtl8187 driver

Hi

I am using the rtl8187 driver based on the mac80211 stack and it is
working pretty well except it can't reassociate to the access point with
WEP encryption enabled (I haven't tested without) of which he lost the
connection.

The association process worked very well:

wlan0: starting scan
wlan0: scan completed
wlan0: Initial auth_alg=0
wlan0: authenticate with AP 00:40:05:cc:38:b4
wlan0: authenticate with AP 00:40:05:cc:38:b4
wlan0: RX authentication from 00:40:05:cc:38:b4 (alg=0 transaction=2
status=0)
wlan0: authenticated
wlan0: associate with AP 00:40:05:cc:38:b4
wlan0: RX AssocResp from 00:40:05:cc:38:b4 (capab=0x51 status=0 aid=2)
wlan0: associated

But if he loses the connection for example because someone is standing
between the AP and the wireless card, he doesn't try to reassociate to
the wireless LAN and I get this:

wlan0: No ProbeResp from current AP 00:40:05:cc:38:b4 - assume out of range
wlan0: No STA entry for own AP 00:40:05:cc:38:b4
wlan0: No STA entry for own AP 00:40:05:cc:38:b4
wlan0: No STA entry for own AP 00:40:05:cc:38:b4

After stopping the interface and starting it an other time the card is
connecting to the AP

wmaster0: Does not support passive scan, disabled
wlan0: Initial auth_alg=0
wlan0: authenticate with AP 00:40:05:cc:38:b4
wlan0: authenticate with AP 00:40:05:cc:38:b4
wlan0: RX authentication from 00:40:05:cc:38:b4 (alg=0 transaction=2
status=0)
wlan0: authenticated
wlan0: associate with AP 00:40:05:cc:38:b4
wlan0: RX AssocResp from 00:40:05:cc:38:b4 (capab=0x51 status=0 aid=2)
wlan0: associated

mac80211 doesn't handle reassociation when a connection is lost. It is 
recommended to configure mac80211 with either wpa_supplicant or 
NetworkManager (which in turn uses wpa_supplicant). However, since we're 
trying to have a reasonable level of compatibility with userspace that use 
wireless tools directly to connect, some reassociation is probably 
appropriate to implement.
