    wlcore: use separate HW queue for each AC in each vif

    ariknem committed with elp Nov 8, 2012
    Start using the new hw_queue mechanism in mac80211 and give each AC in
    each vif its own hw_queue number. This allows us to stop an AC in a vif
    independently from other vifs.
    
    Change the Tx watermark handling functions to count packets per AC in
    vif. From now on fast links should not be able to hurt the throughput
    of slow links on the same AC but on different vifs.
    
    Change internal queue mgmt functions to operate per vif, to support the
    new Tx watermark granularity. Make the global versions of the queue
    stop/start functions to use the global mac80211 API for queue mgmt. This
    helps in situations where the driver currently doesn't know all the vifs
    that reside in mac80211. Recovery is a good example for such a case.

    wlcore: use link count for single-STA-PSM optimization

    ariknem committed with elp Oct 22, 2012
    Only allow a PSM STA to congest FW memory when it is the single active
    link. Being a single STA doesn't imply a single link - there might be
    other links on other roles.

    wl18xx: limit Tx for the AP single-STA-in-PSM case

    ariknem committed with elp Oct 21, 2012
    Treat a single connected STA in PSM as a slow link and regulate Tx speed
    according to slow link priority/stop thresholds.
    This allows us to avoid flooding the FW, while delivering decent
    throughput to a peer in forced-PSM.

    wlcore/wl18xx: change priority calculations for links

    ariknem committed with elp Oct 21, 2012
    Update the 18xx FW status private part to include Tx related link
    priorities. Introduce new HW ops to determine link priority per chip
    family.
    
    For 18xx the changes are:
    - Suspended links are at most low priority and Tx for them is stopped
      beyond the suspend threshold.
    - Active links now get their thresholds directly from FW
    - There's a new "stop" threshold for active links, at which point a link
      stops receiving new packets.
    
    Update the min 18xx FW version required to make sure suspended links
    bitmap is advertised by the FW.

    wlcore: add new reg-domain configuration command

    victorgld committed with elp Nov 5, 2012
    In 18xx the calibration process of the PHY Cortex domain
    requires to perform an active calibration of the channel
    before it can be used for transmission. To fulfill world
    wide regulatory restrictions, fw should be always
    synchronized/updated with current CRDA configuration.
    Add a new "CMD_DFS_CHANNEL_CONFIG" command to update the
    fw with current reg-domain, this command passes a bit map
    of channels that are allowed to be used for transmission.
    
    The driver shall update the fw during initialization and
    after each change in the current reg-domain
    configuration. The driver will save the channel number of
    incoming beacons during the scan process, as they might
    be a result of the passive scan on
    "IEEE80211_CHAN_PASSIVE_SCAN" channel and will update the
    fw accordingly once the scan is finished, the purpose of
    this is to be ready in case of the authentication request
    on one of these disabled (uncalibrated) channels.
    
    The new command requires to wait for the fw completion
    event "DFS_CHANNELS_CONFIG_COMPLETE_EVENT".
    
    No scan commands (including the sched scan) can be
    executed concurrently with the "CMD_DFS_CHANNEL_CONFIG",
    wl->mutex ensures that.

    These are accessed without a lock when ending STA PSM. If the
    sta_cleanup timer accesses these lists at the same time, we might crash.

    Under this mode the chip is powered on including sdio
    but no FW is downloaded and run, interrupts are not enabled, etc...
    
    This mode is intended to allow RTTT to bridge sdio as a transport

    Driver only provides sdio access using the dev_mem debugfs file.

    wlcore: increase scan dwell times if no activity

    There's a limit on scan dwell times of max 30ms in order
    to avoid degrading voip traffic which could be going on
    while scanning. However these dwell times increase the
    chance of missing out on nearby APs leading to partial
    scan results. Allow configuration of longer dwell times
    in case there no active interface (i.e. no STA associated
    or AP up).
