* ath6kl: make sure WLAN power save is enabled during suspendChilam Ng2011-11-11
| | | | | | | | | | Power save is enabled during ath6kl init. But when user space disables power save, the system will go into suspend with power save disabled. The ath6kl driver will now explicitly enable power save prior to entering suspend and restore its previous setting upon resume Signed-off-by: Chilam Ng <chilamng@qca.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

* ath6kl: fix TCP corruptionJouni Malinen2011-09-27
| | | | | | | | | | | | | | | Commit 94e532d1a ("ath6kl: Fix system freeze under heavy data load") aligns the skb data without checking if the skb is cloned. Because of this ath6kl can corrupt the local TCP stack information that can result in TCP retransmission failing and TCP connections stalling. To avoid the corruption we need to copy the skb. Now the alignment in ath6kl_htc_tx_buf_align() doesn't corrupt TCP packets anymore (and is not even used for the cloned skb's that got copied since the alignment of the data is handled at the copy time).

| | | | | | | | | | | | | Driver does not report disconnect event properly when in connecting state, this leads to issues failures in starting reconnection. Send a disconnect command to target when a disconnect event is received with reason code other than 3 (DISCONNECT_CMD - disconnect request from host) to make the frimware stop trying to connect even after giving disconnect event.

* ath6kl: pass only unicast frames for aggregationKalle Valo2011-09-23
| | | | | | | | | | | | | | | | | | | | When pinging form ar6003 to the AP RTT was high even when power save was disabled: 100 packets transmitted, 97 received, 3% packet loss, time 99125ms rtt min/avg/max/mdev = 1.875/46.733/795.506/139.181 ms After some investigation one reason for this was that received multicast traffic confused the aggrecation logic and caused 400 ms timeouts when receiving multicast frames from AP. A simple way to fix is to pass only unicast frames for aggregation. This improves RTT: 100 packets transmitted, 99 received, 1% packet loss, time 99144ms rtt min/avg/max/mdev = 2.083/13.084/403.390/56.794 ms Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

* ath6kl: Indicate the roaming capability of the firmwareVivek Natarajan2011-09-22
| | | | | | | | | | | | | | When the rssi of the current AP drops, both wpa_supplicant and the firmware may do a background scan to find a better AP and try to associate. This might lead to a race condition where both may try to connect to some AP based on their scan results.

| | | | | | | | | | | 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.

* ath6kl: Remove unnecessary bssinfo event header conversionJouni Malinen2011-09-22
| | | | | | | | | | | | | | 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).

| | | | | | | | | | | | | | | | 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.

* ath6kl: Fix BSS update on roamingJouni Malinen2011-09-22
| | | | | | | | | | | | | | | | This fixes the BSS "update" just before the connected or roamed event. The previous implementation was completely broken: it forced a hardcoded signal strength and IEs from Association _Request_ frame instead of any Beacon information. This broke various things, including PMKSA caching. The current workaround for creating a dummy BSS entry before the roamed event is not exactly ideal, but that is quite a bit better than the previous state. As a future improvement, cfg80211 could potentially be extended to allow this type of use or ath6kl could delay sending the roamed event before receiving a BSS info event.
