      This one is all from Johannes:
      
      "Here are a few small fixes for the current cycle: radiotap TX flags were
      wrong (fix by Bob), Chun-Yeow fixes an SMPS issue with mesh interfaces,
      Eliad fixes a locking bug and a cfg80211 state problem and finally
      Henning sent me a fix for IBSS rate information."
      
      Please let me know if there are problems!

      Revert "sctp: optimize the sctp_sysctl_net_register" · eb9f3705
      wangweidong authored
      This revert commit efb842c4("sctp: optimize the sctp_sysctl_net_register"),
      Since it doesn't kmemdup a sysctl_table for init_net, so the
      init_net->sctp.sysctl_header->ctl_table_arg points to sctp_net_table
      which is a static array pointer. So when doing sctp_sysctl_net_unregister,
      it will free sctp_net_table, then we will get a NULL pointer dereference
      like that:

      mdio_bus: fix devm_mdiobus_alloc_size export · 93dccc59
      Arnd Bergmann authored
      commit 6d48f44b "mdio_bus: implement devm_mdiobus_alloc/devm_mdiobus_free"
      introduced a new function devm_mdiobus_alloc_size() but added an export
      for a different function devm_mdiobus_alloc(), which was obviously
      a simple mistake that leads to  build error whenever this function is
      used from a loadable module:
      
      ERROR: "devm_mdiobus_alloc_size" [drivers/net/ethernet/ti/davinci_mdio.ko] undefined!

      bonding: make a generic sysfs option store and fix comments · dc3e5d18
      Nikolay Aleksandrov authored
      Introduce a generic option store function for sysfs and remove the
      specific ones. The attribute name is used to match against the option
      which is to be set.
      Also adjust the "name" of tlb_dynamic_lb option to match the sysfs
      entry and fix the comments and comment style in bond_sysfs.c
      The comments which showed obvious behaviour (i.e. behaviour that's seen
      in the option's entry) are removed, the ones that explained important
      points about the setting function have been moved above the respective
      set function in bond_options.c
      
      There's only 1 exception: num_unsol_na/num_grat_arp since it has 2 names

      Yuval Mintz authored
      Commit 91ebb928b "bnx2x: Add support for Multi-Function UNDI" contains a bug
      which prevent the emptying of the device's Rx buffers before reset.
      As a result, on new boards it is likely HW will reach some fatal assertion
      once its interfaces load after UNDI was previously loaded.

      Revert "net: eth: cpsw: Correctly attach to GPIO bitbang MDIO driver" · 59993f48
      Johan Hovold authored
      This reverts commit f8d56d8f ("net:
       eth: cpsw: Correctly attach to GPIO bitbang MDIO driver").
      
      Fix potential null-pointer dereference at probe if the mdio-gpio device
      has not been successfully probed yet.
      
      The offending commit is plain wrong for a number of reasons. First of
      all it accesses internal driver data of an unrelated device. Neither
      does it check that the data is non-null (which it is in case the device
      has not been probed yet).
      
      Furthermore, the decision on whether to treat any driver data according
      to the mdio-gpio driver's internals is made based on the node name. But
      the name is not compared against "mdio" which is the normal name for the
      node, but rather against "gpio" which the node does not have to be named
      (and shouldn't be according to the binding documentation). [ If this
      hack is to be kept out-of-tree it should at least be matching against
      the compatible property. ]
