      net: convert multicast list to list_head · 22bedad3
      Jiri Pirko authored
      
      
      Converts the list and the core manipulating with it to be the same as uc_list.
      
      +uses two functions for adding/removing mc address (normal and "global"
       variant) instead of a function parameter.
      +removes dev_mcast.c completely.
      +exposes netdev_hw_addr_list_* macros along with __hw_addr_* functions for
       manipulation with lists on a sandbox (used in bonding and 80211 drivers)

      mac80211: Fix HT rate control configuration · 4fa00437
      Sujith authored
      
      
      Handling HT configuration changes involved setting the channel
      with the new HT parameters and then issuing a rate_update()
      notification to the driver.
      
      This behavior changed after the off-channel changes. Now, the channel
      is not updated with the new HT params in enable_ht() - instead, it
      is now done when the scan work terminates. This results in the driver
      depending on stale information, defaulting to non-HT mode always.
      
      Fix this by passing the new channel type to the driver.

      cfg80211/mac80211: allow registering for and sending action frames · 026331c4
      Jouni Malinen authored
      
      
      This implements a new command to register for action frames
      that userspace wants to handle instead of the in-kernel
      rejection. It is then responsible for rejecting ones that
      it decided not to handle. There is no unregistration, but
      the socket can be closed for that.
      
      Frames that are not registered for will not be forwarded
      to userspace and will be rejected by the kernel, the
      cfg80211 API helps implementing that.
      
      Additionally, this patch adds a new command that allows
      doing action frame transmission from userspace. It can be
      used either to exchange action frames on the current
      operational channel (e.g., with the AP with which we are
      currently associated) or to exchange off-channel Public
      Action frames with the remain-on-channel command.

      mac80211: allow station add/remove to sleep · 34e89507
      Johannes Berg authored
      
      
      Many drivers would like to sleep during station
      addition and removal, and currently have a high
      complexity there from not being able to.
      
      This introduces two new callbacks sta_add() and
      sta_remove() that drivers can implement instead
      of using sta_notify() and that can sleep, and
      the new sta_add() callback is also allowed to
      fail.
      
      The reason we didn't do this previously is that
      the IBSS code wants to insert stations from the
      RX path, which is a tasklet, so cannot sleep.
      This patch will keep the station allocation in
      that path, but moves adding the station to the
      driver out of line. Since the addition can now
      fail, we can have IBSS peer structs the driver
      rejected -- in that case we still talk to the
      station but never tell the driver about it in
      the control.sta pointer. If there will ever be
      a driver that has a low limit on the number of
      stations and that cannot talk to any stations
      that are not known to it, we need to do come up
      with a new strategy of handling larger IBSSs,
      maybe quicker expiry or rejecting peers.

      mac80211: re-enable re-transmission of filtered frames · c6fcf6bc
      Johannes Berg authored
      
      
      In an earlier commit,
      
          mac80211: disable software retry for now
      
          Pavel Roskin reported a problem that seems to be due to
          software retry of already transmitted frames. It turns
          out that we've never done that correctly, but due to
          some recent changes it now crashes in the TX code. I've
          added a comment in the patch that explains the problem
          better and also points to possible solutions -- which
          I can't implement right now.
      
      I disabled software retry of failed/filtered frames
      because it was broken. With the work of the previous
      patches, it now becomes fairly easy to re-enable it
      by adding a flag indicating that the frame shouldn't
      be modified, but still running it through the transmit
      handlers to populate the control information.

      mac80211: add U-APSD client support · ab13315a
      Kalle Valo authored
      
      
      Add Unscheduled Automatic Power-Save Delivery (U-APSD) client support. The
      idea is that the data frames from the client trigger AP to send the buffered
      frames with ACs which have U-APSD enabled. This decreases latency and makes it
      possible to save even more power.
      
      Driver needs to use IEEE80211_HW_UAPSD to enable the feature. The current
      implementation assumes that firmware takes care of the wakeup and
      hardware needing IEEE80211_HW_PS_NULLFUNC_STACK is not yet supported.
      
      Tested with wl1251 on a Nokia N900 and Cisco Aironet 1231G AP and running
      various test traffic with ping.

      mac80211: add functions to create PS Poll and Nullfunc templates · 7044cc56
      Kalle Valo authored
      
      
      Some hardware, for example wl1251 and wl1271, handle the transmission
      of power save related frames in hardware, but the driver is responsible
      for creating the templates. It's better to create the templates in mac80211,
      that way all drivers can benefit from this.
      
      Add two new functions, ieee80211_pspoll_get() and ieee80211_nullfunc_get()
      which drivers need to call to get the frame. Drivers are also responsible
      for updating the templates after each association.
      
      Also new struct ieee80211_hdr_3addr is added to ieee80211.h to make it
      easy to calculate length of the Nullfunc frame.

      cfg80211/mac80211: Use more generic bitrate mask for rate control · 37eb0b16
      Jouni Malinen authored
      
      
      Extend struct cfg80211_bitrate_mask to actually use a bitfield mask
      instead of just a single fixed or maximum rate index. This change
      itself does not modify the behavior (except for debugfs files), but it
      prepares cfg80211 and mac80211 for a new nl80211 command for setting
      which rates can be used in TX rate control.
      
      Since frames are now going through the rate control algorithm
      unconditionally, the internal IEEE80211_TX_INTFL_RCALGO flag can now
      be removed. The RC implementations can use the rate_idx_mask value to
      optimize their behavior if only a single rate is enabled.
      
      The old max_rate_idx in struct ieee80211_tx_rate_control is maintained
      (but commented as deprecated) for backwards compatibility with existing
      RC implementations. Once these implementations have been updated to
      use the more generic rate_idx_mask, the max_rate_idx value can be
      removed.

      mac80211: Select lowest rate based on basic rate set in AP mode · e00cfce0
      Jouni Malinen authored
      
      
      If the basic rate set is configured to not include the lowest rate
      (e.g., basic rate set = 6, 12, 24 Mbps in IEEE 802.11g mode), the AP
      should not send out broadcast frames at 1 Mbps. This type of
      configuration can be used to optimize channel usage in cases where
      there is no need for backwards compatibility with IEEE 802.11b-only
      devices.
      
      In AP mode, mac80211 was unconditionally using the lowest rate for
      Beacon frames and similarly, with all rate control algorithms that use
      rate_control_send_low(), the lowest rate ended up being used for all
      broadcast frames (and all unicast frames that are sent before
      association). Change this to take into account the basic rate
      configuration in AP mode, i.e., use the lowest rate in the basic rate
      set instead of the lowest supported rate when selecting the rate.
