  2. wlcore: block most mac80211 ops on p2p mgmt iface (INTERNAL)

    ariknem committed with elp Aug 5, 2012
    In general, p2p management interfaces cannot send vif-specific commands
    to FW, as the vif role id is invalid. Only off-channel data and scans
    happen on this vif, so most ops are not relevant.
    
    If the vif is a p2p mgmt vif, block non relevant mac80211 ops.

    When starting a p2p mgmt interface, enable its device role. This
    allows us to keep the sta role disabled and scan on the dev role.

    To enhance scan abilities by being able to setup some low level
    scan parameters dynamically during NL80211_CMD_TRIGGER_SCAN
    command.
    
    Exposing 3 new attributes:
      NL80211_ATTR_SCAN_MIN_DWELL: Minimum scan dwell time (in TUs), u32
    	attribute to setup minimum time to wait on each channel, if received
    	at least one probe response during this period will continue waiting
    	%NL80211_ATTR_SCAN_MAX_DWELL, otherwise will move to next channel.
     	This is optional attribute, so if it's not set driver should
    	use hardware default values.
      NL80211_ATTR_SCAN_MAX_DWELL: Maximum scan dwell time (in TUs), u32
    	attribute to setup maximum time to wait on each channel.
    	This is optional attribute, so if it's not set driver should
    	use hardware default values.
      NL80211_ATTR_SCAN_NUM_PROBE:  Attribute (u8) to setup number of probe
     	requests to transmit on each active scan channel, used with
    	NL80211_CMD_TRIGGER_SCAN command.

  15. wlcore: force recheck of version.h and use -dirty if needed (INTERNAL)

    Luciano Coelho committed with elp Feb 20, 2012
    If the tree was changed and unstaged or if a new tag was added, we
    were not regenerating the version.h file, so it would contain outdated
    information.
    
    To fix this, force the version.h file to be rechecked during make and
    use __TIMESTAMP__ instead of using the shell's date command, so that
    we don't regenerate it everytime.
    
    Additionally, use --dirty in git describe to mark dirty trees as such.
    
    With compat-wireless, we shouldn't force the version.h file checks,
    otherwise it will overwrite what we generated in compat-wireless
    itself.  This was only needed for dirty trees anyway.  The side-effect
    is that the version will not be regenerated when the tree becomes
    dirty.
    
    Thanks Eliad for the help with this.

  16. wlcore/wl18xx/wl12xx: add version and timestamp strings (INTERNAL)

    elp committed Feb 7, 2012
    In order to allow better version control, add version
    and timestamp strings into the wl12xx module.
    
    These strings will be printed on driver load, and when
    reading the driver_state.
    
    (this is not going to work well in compat, because it
    copies all the files instead of compiling them in the
    original tree, so the version of the compat tree will
    appear as the driver version. we can workaround it
    with the additional makefile hacks...)
    
    NOTE: I couldn't find how to make one module recompile
    when the .h file of another module was changed, so i
    just duplicated it for now.

  26. wlcore: add counters with reasons for aggr packet sending (DEBUG)

    Luciano Coelho committed with elp May 21, 2012
    Count the reasons that triggered us to send the buffer to the firmware
    for transmission.  Count buffer_full, fw_buffer_full, other reasons
    and no_data left to send.
    
    This is useful when debugging throughput issues.
    
    To have a better understanding of what is going on in the TX data
    path, we can count the number of times we sent n packets.  For
    example, if we sent 10 times aggregations of 2 packets, we print [2] =
    10.
    
    Instead of counting the reasons as an overall value, we count the
    reasons for each number of packets used in the aggregation.

    When running with DT, we no longer have a board file that can set up the

    Since some platforms use a gpio-irq, add support for passing either the
    irq number or the gpio number. For the latter case, the driver will
    request the gpio and convert it to the irq number. If an irq is
    specified, it'll be used as is.

    the device is released. Dereference to our private data first.]

  29. mac80211: use legacy mode for all ACs [INTERNAL]

    eyalsh committed with elp Jun 26, 2012
    AVM FritzBox 7390 has a weird behaviour where once we enable
    U-APSD only on the VO AC it limits the rate of the packets
    it sends to 39Mbps and doesn't do AMPDU aggregation.
    This causes a big degradation in throughput obviously.
    It's important to note that this isn't related to PS and happens
    also when ACTIVE is forced. The traffic affected is sent in BE AC.
    Once legacy mode for all ACs is used the AP begins using higher rates
    as well as AMPDU aggregation which improves throughput significantly.
    
    In order to deal with this AP and potentially others switch to
    using legacy mode for all ACs by default.

    a roc might get cancelled (by the user) after it was

    In this case, the hw_roc_done work might expire the
    roc that has just started (when the previous roc
    was cancelled), which will get mac80211 and the

    notification.
