      ====================
      Here's one more bluetooth pull request for 3.19. We've got two fixes:
      
       - Fix for accepting connections with old user space versions of BlueZ
       - Fix for Bluetooth controllers that don't have a public address
      
      Both of these are regressions that were introduced in 3.17, so the
      appropriate Cc: stable annotations are provided.
      
      Please let me know if there are any issues pulling. Thanks.

      o Paul made a Kconfig dependency fix to ipw2200, it was not possible to
        enable that driver because Wireless Extensions is now disabled by default.
      
      o Mika fixed brcmfmac not to crash when platform data is not populated
      
      o Emmanuel provided few fixes to iwlwifi, he says:
      
        "I have here new device IDs and a fix for double free bug I
        introduced. I also fix an issue with the RFKILL interrupt - the HW
        needs us to ACK the interrupt again after we reset it. Liad fixes an
        issue with the firmware debugging infrastructure. While working on
        torture scenarios of firmware restarts, Eliad found an issue which
        he fixed."

      net: Generalize ndo_gso_check to ndo_features_check · 5f35227e
      Jesse Gross authored
      GSO isn't the only offload feature with restrictions that
      potentially can't be expressed with the current features mechanism.
      Checksum is another although it's a general issue that could in
      theory apply to anything. Even if it may be possible to
      implement these restrictions in other ways, it can result in
      duplicate code or inefficient per-packet behavior.
      
      This generalizes ndo_gso_check so that drivers can remove any
      features that don't make sense for a given packet, similar to
      netif_skb_features(). It also converts existing driver
      restrictions to the new format, completing the work that was
      done to support tunnel protocols since the issues apply to
      checksums as well.
      
      By actually removing features from the set that are used to do
      offloading, it solves another problem with the existing
      interface. In these cases, GSO would run with the original set
      of features and not do anything because it appears that
      segmentation is not required.

      This property is no longer used in the code yet the code looks for it in the device tree.
      It does not cause an error if it's not in the tree.

      net: phy: micrel: use generic config_init for KSZ8021/KSZ8031 · d0e1df9c
      Johan Hovold authored
      Use generic config_init callback also for KSZ8021 and KSZ8031.
      
      This has been avoided this far due to commit b838b4ac ("phy/micrel:
      KSZ8031RNL RMII clock reconfiguration bug"), which claims that the PHY
      becomes unresponsive if the broadcast-disable flag is set before
      configuring the clock mode.
      
      Turns out that the problem seemingly worked-around by the above
      mentioned commit was really due to a hardware-configuration issue, where
      the PHY was in fact strapped to address 3 rather than 0.

      net/core: Handle csum for CHECKSUM_COMPLETE VXLAN forwarding · 2c26d34b
      Jay Vosburgh authored
      When using VXLAN tunnels and a sky2 device, I have experienced
      checksum failures of the following type:
      
      [ 4297.761899] eth0: hw csum failure
      [...]
      [ 4297.765223] Call Trace:
      [ 4297.765224]  <IRQ>  [<ffffffff8172f026>] dump_stack+0x46/0x58
      [ 4297.765235]  [<ffffffff8162ba52>] netdev_rx_csum_fault+0x42/0x50
      [ 4297.765238]  [<ffffffff8161c1a0>] ? skb_push+0x40/0x40
      [ 4297.765240]  [<ffffffff8162325c>] __skb_checksum_complete+0xbc/0xd0
      [ 4297.765243]  [<ffffffff8168c602>] tcp_v4_rcv+0x2e2/0x950
      [ 4297.765246]  [<ffffffff81666ca0>] ? ip_rcv_finish+0x360/0x360
      
      	These are reliably reproduced in a network topology of:
      
      container:eth0 == host(OVS VXLAN on VLAN) == bond0 == eth0 (sky2) -> switch
      
      	When VXLAN encapsulated traffic is received from a similarly
      configured peer, the above warning is generated in the receive
      processing of the encapsulated packet.  Note that the warning is
      associated with the container eth0.
      
              The skbs from sky2 have ip_summed set to CHECKSUM_COMPLETE, and
      because the packet is an encapsulated Ethernet frame, the checksum
      generated by the hardware includes the inner protocol and Ethernet
      headers.
      
      	The receive code is careful to update the skb->csum, except in
      __dev_forward_skb, as called by dev_forward_skb.  __dev_forward_skb
      calls eth_type_trans, which in turn calls skb_pull_inline(skb, ETH_HLEN)
      to skip over the Ethernet header, but does not update skb->csum when
      doing so.
      
      	This patch resolves the problem by adding a call to
      skb_postpull_rcsum to update the skb->csum after the call to
      eth_type_trans.
