2014-11-17mwifiex: add auto TDLS supportAvinash Patil
This patch adds auto TDLS support to mwifiex. Auto TDLS functionality works as follows: 1. Whenever userspace application has triggered TDLS connection with any peer, driver would store this peer mac address details in its database. 2. After this driver whenever driver receives packet on direct link, it would store rssi and timestamp in peer information. 3. Whenever a packet is to be transmitted to non-AP peer in station mode, driver would check if TDLS link can be established by looking at peer RSSI information. Driver would initiate TDLS setup in such cases. 4. Periodic timer is used for updating peer information. 5. Auto TDLS peer list & timer are cleared during disconnection or driver unload.

2014-09-15mwifiex: bring in scan channel gap featureAvinash Patil
With scan channel gap when any station/AP is active, FW comes back to connected channel for any pending data transfter after scanning each channel. We set scan channel gap TLV to FW in scan command when any of the interface is active. This enables scan channel gap in FW. Also when scan channel gap is enabled, we would scan maximum channels allowed by FW. Scan channel gap is supported only on FW with V15 FW API.

2014-02-12mwifiex: provision for holding and restoring packets during TDLS setupAvinash Patil
While TDLS link is being setup, few packets from this station to peer station may be buffered at AP. It may happen that once TDLS link is setup, packets sent from station to peer on direct link get delivered before traffic from AP arrives at peer station. This results into packet reordering issue at peer station. To avoid this, we hold data packets destined to TDLS peer during TDLS setup. These packets are moved to temperory TDLS TX queue. Upon successful TDLS setup, they are moved to RA list created for this peer. Upon failure, packets are moved back to AP's RA list for that particular TID.

2013-07-22mwifiex: fix IRQ enable/disableDaniel Drake
During tear down (e.g. mwifiex_sdio_remove during system suspend), mwifiex left IRQs enabled for a significant period of time when it was unable to handle them correctly. This caused interrupt storms and interfered with the bluetooth interface on the same SDIO card. Solve this by disabling interrupts at the point when they can no longer be handled correctly, which is at the start of mwifiex_remove_card(). For cleanliness, we now enable interrupts in the mwifiex_add_card() path, to be symmetrical with the disabling of interrupts. We also couple the registration of the sdio IRQ handler with the actual enable/disable of interrupts at the hardware level. I also removed a write to this register in mwifiex_init_sdio which seemed pointless and won't cause any ill effects now that we only register the SDIO IRQ handler when we are ready to accept interrupts.

2013-04-08mwifiex: fix negative cmd_pending countBing Zhao
cmd_pending is increased in mwifiex_wait_queue_complete() and decreased in mwifiex_complete_cmd() currently. If there are two or more commands in the cmd_pending_q the main worker thread will pick up next command from cmd_pending_q automatically after finishing current command. As a result mwifiex_wait_queue_complete() will not be called because the command is alreay completed. This leads to a negative number in cmd_pending count. Fix it by increasing cmd_pending when a cmd is queued into cmd_pending_q and decreasing when that cmd is recycled. For scan commands we don't perform inc/dec operations until it's moved from scan_pending_q to cmd_pending_q. This covers both synchronous and asynchronous commands.

This patch adds support for multiple TX queues inside mwifiex driver. Four different queues according to WMM access categories are defined for each virtual interface. When a packet is received from netdev for transmission, tx pending count for particular queue is incremented and if tx pending count has reached upper water-mark, this queue is stopped instead of stopping all queues. Similarly when a packet is successfully transmitted from device, tx pending count is decremented per queue and if pending count falls below lower water-mark, queue operations are again resumed. This ensures that not all tranmission is blocked if traffic with particular TOS value suddenly increases. Also wake all queues after association/IBSS_join/uAP_BSS_start to enable traffic on all queues.
