2011-02-25mac80211: make tx() operation return voidJohannes Berg
The return value of the tx operation is commonly misused by drivers, leading to errors. All drivers will drop frames if they fail to TX the frame, and they must also properly manage the queues (if they didn't, mac80211 would already warn). Removing the ability for drivers to return a BUSY value also allows significant cleanups of the TX TX handling code in mac80211. Note that this also fixes a bug in ath9k_htc, the old "return -1" there was wrong.

mac80211 stores the association state in ieee80211_bss_conf. Use this and remove the local state, which is incorrect anyway since it is stored globally and not on a per-VIF basis.

2011-02-23wl12xx: AP-mode - management of links in PS-modeArik Nemtsov
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.

When operating in AP mode the wl1271 hardware filters out null-data packets as well as management packets.

2011-02-23wl12xx: AP-mode - TX queue per link in ACArik Nemtsov
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: fix potential race condition with TX queue watermarkArik Nemtsov
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.
