Subject: ath6kl: Delay initial group key setup in AP mode

The target is not ready to accept addkey commands until the connect
event has been delivered, so delay these operations for the initial GTK.
In addition, properly set interface connected and mark netdev ready when
the AP mode setup has been completed.

Subject: ath6kl: Notify cfg80211 of TX status of mgmt_tx frames

Use WMI_TX_STATUS_EVENTID event to generate cfg80211_mgmt_tx_frame()
calls. Since we support only a single pending frame for now, use the
hardcoded cookie value 1 and store a copy of the pending frame in
the driver.

From bdf5396be177b689c00ae6ebed00d13fafaed36e Mon Sep 17 00:00:00 2001
From: Kalle Valo <kvalo@qca.qualcomm.com>
Date: Fri, 2 Sep 2011 10:32:04 +0300
Subject: ath6kl: add firmware log support

Firmware sends binary logs with WMIX_DBGLOG_EVENTID event. Create
a buffer which stores the latest logs and which can be copied from
fwlog debugfs file with cp command.

To save memory firmware log support is enabled only when CONFIG_ATH6KL_DEBUG
is enabled.

Subject: ath6kl: Add debugfs entry to modify roaming parameters.

Firmware initiates roaming only after it reaches a rssi of 20.
This lower rssi threshold can be modified through a wmi command
to modify the roaming behavior.

kvalo: rename debugfs functions and move comment about rssi units next to
ath6kl_wmi_set_roam_lrssi_cmd()

Subject: ath6kl: Fix AP mode connect event parsing and TIM updates

This cleans up the connect event parsing by defining a union in
struct wmi_connect_event to match with the three possible sets of
fields that the target uses depending on which type of connect
event is being indicated. In addition, two AP cases are now
separated from ath6kl_connect_event() so that correct field names
can be used to make it actually possible to understand what the
code is doing.

The bug hiding in the previous mess was in parsing the AID incorrectly
when processing the new station connecting event in AP mode. The fix
here for that is also fixing TIM updates for PS buffering to use the
correct AID.

Subject: ath6kl: Replace internal node table with cfg80211 BSS table

The internal node table in ath6kl was not really used for any useful
purpose. It was just used to collect scan results during a scan and then
provide them in a burst to cfg80211 at the completion of the scan. There
is no point in doing this since cfg80211 is perfectly capable of
maintaining the BSS table and the BSS inform messages are sent in
separate function calls anyway.

This provides more complete information in the cfg80211 BSS table since
this allows Beacon and Probe Response frames to be distinguished and IEs
from them reported separately.

Subject: ath6kl: Remove the unused node table implementation

Now that the scan results are reported directly to the cfg80211 BSS
table there is no need for maintaining this internal node table
implementation for scan results. Remove the definitions and node
table functions.

Subject: ath6kl: Remove unnecessary bssinfo event header conversion

There is no point in unconditionally converting the bssinfo header
to the old version since only the new header is being used and the
driver can as well read the values from it when needed. Leaving out
the conversion saves some extra memory copying.

In addition, use the calculated "rssi" value snr - 95 dBm to get the
proper value in cfg80211 BSS table (i.e., something that more or less
matches with the value used in STA info).

Subject: ath6kl: Update BSS information after connection

Since we may end up using a dummy BSS entry when roaming, allow one Beacon
frame -based bssinfo from the current BSS to be processed prior to starting
to filter all bssinfo events. This allows cfg80211 BSS table to be filled
with proper data in the roaming case where the full Beacon data may not
have been present at the time of roamed event.
