* ath9k_hw: clean up hardware revision checksFelix Fietkau2011-09-19
| | | | | | | | | - AR_SREV_5416_20_OR_LATER is always true, remove it - AR_SREV_9280_20_OR_LATER is always true within eeprom_4k.c and eeprom_9287.c - (AR_SREV_9271 || AR_SREV_9285) is always true in eeprom_4k.c Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W.

| | | | | | | | When the driver inserts padding between the 802.11 header and data, it needs to set the hdr variable to the new header location. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>

| * wl12xx: support p2p interfacesEliad Peller2011-09-14
| | | | | | | | | | | | | | | | | | | | Declare support for p2p interfaces, and create p2p_cli/p2p_go roles when being asked for. Indicate we are using a p2p interface by setting the wl->p2p flag. Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
| * wl12xx: set mac80211 flags for A-MPDU aggregation supportArik Nemtsov2011-09-14
| | | | | | | | | | | | | | | | | | | | | | We set the mac80211 flag for A-MPDU support and also indicate that Tx-agg session setup is performed in HW.

| * wl12xx: AP mode - clean BA and queue state in tx_resetArik Nemtsov2011-09-14
| | | | | | | | | | | | | | | | | | Reset the BA state of all connected stations and explicitly clear the Tx queues. The latter is needed for clearing dummy packets from tx_queue_count. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
| * wl12xx: AP mode - enable the BA constraint event from the FWArik Nemtsov2011-09-14
| | | | | | | | | | | | | | | | | | | | | | Unblock the RX BA constraint event from firmware in AP mode as well. This allows us to stop RX BA sessions when the FW requests it. In addition refactor the handler for this event to make the flow clearer. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
| * wl12xx: don't regulate links when a single STA is connectedArik Nemtsov2011-09-14
| | | | | | | | | | | | | | | | | | | | | | When operating as AP track the number of connected stations. When a single STA is connected don't regulate the PS status of the link. Since this is the only STA connected, there's no point holding space in FW for other links. This will speed up communications with a single connected STA in PSM.

| | | | | | | | | | | | | | | | | | | | Check a STA is associated before regulating its PS-status in mac80211. Should never happen, so warn as a precaution.

| * wl12xx: don't indicate up PS-filtered dummy packetsArik Nemtsov2011-09-14
| | | | | | | | | | | | | | | | | | | | | | Dummy packets are currently only sent on the system_hlid link. The system_hlid link should never be filtered for PS (as it is not a STA link). Even so, for correctness, don't indicate dummy packets up. The skb does not belong to mac80211 and as such does not contain a correct skb->cb.

| * wl12xx: ignore sched scan match sets without SSIDLuciano Coelho2011-09-14
| | | | | | | | | | | | | | | | | | | | For now, cfg80211 only support match sets with SSIDs, but in the future more parameters will be added. This patch ignores eventual matches that do not contain SSIDs in preparation for the future. This change also affects the case where broadcast SSIDs are used. Matching a broadcast SSID will match everything, so they can be ignored. Signed-off-by: Luciano Coelho <coelho@ti.com>
| * wl12xx: increase number of allowed SSIDs in sched_scanLuciano Coelho2011-09-14
| | | | | | | | | | | | | | | | | | The latest firmware supports up to 16 SSIDs in the scheduled scan lists. Increase the number we report to cfg80211 and increase the min/max dwell time to 30 and 60 TUs respectively, because otherwise we don't have the time to send the probes for all SSIDs. Signed-off-by: Luciano Coelho <coelho@ti.com>
| * wl12xx: add support for sched_scan filtersLuciano Coelho2011-09-14
| | | | | | | | | | | | | | | | | | | | | | Implement support for filtering in scheduled scans. With this commit we now use the match sets passed by cfg80211 to filter on SSIDs. Due to the nature of the wl12xx firmware API, we don't allow SSIDs to be sent in the probe requests if they are not going to match any of the filters. Signed-off-by: Luciano Coelho <coelho@ti.com>

| * wl12xx: remove deprecated CONFIG_WL12XX_HT flagLuciano Coelho2011-09-14
| | | | | | | | | | | | | | | | The driver now support HT properly, so we can always have HT enabled. Remove the WL12XX_HT configuration. Signed-off-by: Luciano Coelho <coelho@ti.com>
| * wl12xx: don't queue a new dummy packet if one is already pendingArik Nemtsov2011-09-14
| | | | | | | | | | | | | | | | | | | | | | | | | | The firmware only asks for one dummy packet at a time, but sometimes we are unable to provide it before a FW timer expires. When this happens, the FW will re-request the dummy packet. If a packet is still queued in the driver queues, do nothing in this case. This prevents spurious dummy packets from clogging up the VO AC.

| * wl12xx: check for ROC on scan_completeEliad Peller2011-09-14
| | | | | | | | | | | | | | | | | | When scan completes, and we are not associated, we should start the dev role and ROC. however, we might already be in this situation (e.g. if we got disconnected during scan). check for it.

| * wl12xx: don't use WL1271_SCAN_OPT_PRIORITY_HIGH flagEliad Peller2011-09-14
| | | | | | | | | | | | | | | | | | When setting the WL1271_SCAN_OPT_PRIORITY_HIGH flag, the driver requests a scan *now*, and the fw doesn't enter psm before scanning, which in turn might cause packets loss.

| | | | | | | | | | | | | | | | | | | | Allow enabling/disabling beacon_filtering by debugfs, in order to reduce the log size while debugging (beacon filtering is disabled by default in AP mode, as beacons are needed for ERP configuration).

| * wl12xx: add module_param to trigger BUG() on recoveryEliad Peller2011-09-14
| | | | | | | | | | | | | | | | | | Crashing on recovery is useful for debugging, as a JTAG can be connected in order to investigate the current fw state. (otherwise, a reconfiguration will occur) Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>

* | ath9k: do not insert padding into tx buffers on AR9380+Felix Fietkau2011-09-16
| | | | | | | | | | | | | | | | | | | | With the new EDMA descriptor format, a single descriptor can contain up to four buffer pointers. By splitting the buffer into two parts, we can let the hardware add the padding internally instead of using memmove on the skb data.

* | ath9k: optimize ath_tx_rc_status usageFelix Fietkau2011-09-16
| | | | | | | | | | | | | | | | | | | | | | | | The only flag that needs to be set when ath_tx_rc_status is called with rc_update == false is the IEEE80211_TX_STAT_TX_FILTERED flag. All other data is ignored in that case. This flag can be set from ath_tx_complete_buf instead, so that we can drop a few redundant calls to ath_tx_rc_status and remove the rc_update function parameter Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W.

* | ath9k: use the new API for setting tx descriptorsFelix Fietkau2011-09-16
| | | | | | | | | | | | | | | | | | | | With the new API, tx descriptors can be written in one single pass instead of having to re-read and rewrite fields from multiple places. This makes the code easier to read and also slightly improves performance on embedded MIPS hardware. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W.

* | ath9k: ensure that rx is not enabled during a resetFelix Fietkau2011-09-16
| | | | | | | | | | | | | | | | | | During a reset, rx buffers are flushed after rx has been disabled. To avoid race conditions, rx needs to stay disabled during the reset, so avoid any calls to ath9k_hw_rxena in that case. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W.
