2011-02-23mwl8k: Tell mac80211 we have rate adaptation in FWNishant Sarmukadam1-1/+8
All mwl8k parts perform rate control in firmware. Make this known to mac80211 so that it does not launch minstrel. Also, because actual tx rate information is not available from the firmware, invalidate the rate status before returning the skb to mac80211.

2011-02-23mwl8k: fix rf_antenna rx argument for APNishant Sarmukadam1-3/+7
When configuring rx antennas using CMD_RF_ANTENNA, the argument input is the number of antennas to be enabled. For AP, we support 3 rx antennas and hence set the field to 3. For tx antennas, value is a bitmap, so 0x7 enables all three.

2011-02-23wl12xx: AP-mode - management of links in PS-modeArik Nemtsov5-12/+186
Update the PS mode of each link according to a bitmap polled from fw_status. Manually notify mac80211 about PS mode changes in connected stations. mac80211 will only be notified about PS start when the station is in PS and there is a small number of TX blocks from this link ready in HW. This is required for waking up the remote station since the TIM is updated entirely by FW. When a station enters mac80211-PS-mode, we drop all the skbs in the low-level TX queues belonging to this sta with STAT_TX_FILTERED to keep our queues clean.

2011-02-23wl12xx: AP-mode - count free FW TX blocks per linkArik Nemtsov4-26/+44
Count the number of FW TX blocks allocated per link. We add blocks to a link counter when allocated for a TX descriptor. We remove blocks according to counters in fw_status indicating the number of freed blocks in FW. These counters are polled after each IRQ.

2011-02-23wl12xx: AP-mode - support HW based link PS monitoringArik Nemtsov1-1/+2
When operating in AP mode the wl1271 hardware filters out null-data packets as well as management packets. This makes it impossible for mac80211 to monitor the PS mode by using the PM bit of incoming frames. Disable mac80211 automatic link PS-mode handling by supporting IEEE80211_HW_AP_LINK_PS in HW flags. Signed-off-by: Arik Nemtsov <[email protected]> Signed-off-by: Luciano Coelho <[email protected]>
2011-02-23wl12xx: report invalid TX rate when returning non-TX-ed skbsArik Nemtsov1-0/+11

2011-02-23wl12xx: AP-mode - TX queue per link in ACArik Nemtsov4-13/+151
When operating in AP-mode we require a per link tx-queue. This allows us to implement HW assisted PS mode for links, as well as regulate per-link FW TX blocks consumption. Split each link into ACs to support future QoS for AP-mode. AC queues are emptied in priority and per-link queues are scheduled in a simple round-robin fashion.

2011-02-23wl12xx: AP-mode - fix race condition on sta connectionArik Nemtsov3-0/+53
If a sta starts transmitting immediately after authentication, sometimes the FW deauthenticates it. Fix this by marking the sta "in-connection" in FW before sending the autentication response. The "in-connection" entry is automatically removed when connection succeeds or after a timeout. Signed-off-by: Arik Nemtsov <[email protected]> Signed-off-by: Luciano Coelho <[email protected]>
2011-02-23wl12xx: fix potential race condition with TX queue watermarkArik Nemtsov1-13/+11
Check the conditions for the high/low TX queue watermarks when the spin-lock is taken. This prevents race conditions as tx_queue_count and the flag checked are only modified when the spin-lock is taken. The following race was in mind: - Queues are almost full and wl1271_op_tx() will stop the queues, but it doesn't get the spin-lock yet. - (on another CPU) tx_work_locked() dequeues 15 skbs from this queue and tx_queue_count is updated to reflect this - wl1271_op_tx() does not check tx_queue_count after taking the spin-lock and incorrectly stops the queue.

2011-02-22wl12xx: declare support for IEEE80211_HW_REPORTS_TX_ACK_STATUSEliad Peller1-1/+2
The wl12xx fw supports ack status reporting for tx frames, so add the IEEE80211_HW_REPORTS_TX_ACK_STATUS flag to our supported features. Since we do the rate control in the fw, we'll probably want to adjust the STA_LOST_PKT_THRESHOLD heuristics in the future, to account for retransmissions as well.
