Samuel Ortiz 9829e1b510 iwmc3200wifi: Try shared auth when open WEP fails
When we fail to associate with an open WEP AP, we fall back to shared auth.
This allows us to support joining a shared auth WEP AP with iwconfig.

Samuel Ortiz 708567e072 iwmc3200wifi: Check for cmd pointer before dereferencing it
The wifi_if_wrapper notification handling code uses a cmd pointer without
checking if it's valid or not. We're dereferencing it because we assume that
we only get to that point if there was a pending command for us. That's not
always true, so we'd better check.

Samuel Ortiz e85498b21d iwmc3200wifi: CT kill support
We set the initial CT (Temperature control) value to 110 degrees.
If the chip goes over that threshold, we hard block the device which will turn
it down. At the same time we schedule a 30 seconds delayed work that unblock
the device (and userspace is supposed to bring it back up), hoping that the
chip will have cooled down by then...

Samuel Ortiz d210176eaa iwmc3200wifi: Handle UMAC stalls and UMAC assert properly
When UMAC stalls or asserts, we want to reset the device. But when we're
associated, the current reset worker will end up calling
cfg80211_connect_result() with the cfg80211 sme layer knowing that we're
reassociating. That ends up with some ugly warnings.
With this patch we're telling the upper layer that we've roamed if
reassociation succeeds, and that we're disconnected if it fails.

Zhu Yi c743627388 iwmc3200wifi: add disconnect work
When the driver receives "connection terminated" event from device,
it could be caused by 2 reasons: the firmware is roaming or the
connection is lost (AP disappears). For the former, an association
complete event is supposed to come within 3 seconds. For the latter,
the driver won't receive any event except the connection terminated.
So we kick a delayed work (5*HZ) when we receive the connection
terminated event. It will be canceled if it turns out to be a roaming
event later. Otherwise we notify SME and userspace the disconnection.

Zhu Yi de15fd31fc iwmc3200wifi: use cfg80211_roamed to send roam event
The device sends connection terminated and [re]association success
(or failure) events when roaming occours. The patch uses
cfg80211_roamed instead of cfg80211_connect_result to notify SME
for roaming.

When we're calling iwm_send_wifi_if_cmd() with the resp flag set, we're
currently waiting on the mlme queue, waiting for some flags here and there to
show up.
This patch adds a wifi_ntfy bitmap, and when we're sending a wifi_if command
expecting an answers, we wait synchronously for it to show up, on a dedicated
queue. The wifi_ntfy bit is set when we receive the corresponding answer.
