      ====================
      Intel Wired LAN Driver Updates 2015-06-04
      
      This series contains updates to i40e and i40evf.
      
      Anjali provides three fixes, first to resolve a Tx queue hang if mixed
      size frags are passed to the driver while using TSO.  There was a corner
      case where we needed to linearize but we were not.  Next fixes a bug in
      the default configuration which prevented a software bridge loaded on the
      PF interface from working correctly because broadcast packets are
      incorrectly looped back.  Lastly fixes an NPAR bug when SRIOV is enabled,
      where we need to be in VEB mode, not VEPA mode at probe.

      i40e: Make sure to be in VEB mode if SRIOV is enabled at probe · fa11cb3d

      If SRIOV is enabled we need to be in VEB mode not VEPA mode at probe.
      This fixes an NPAR bug when SRIOV is enabled in the BIOS.

      i40e: start up in VEPA mode by default · fc60861e
      Anjali Singhai Jain authored
      The patch fixes a bug in the default configuration which
      prevented a software bridge loaded on the PF interface from
      working correctly because broadcast packets are incorrectly
      looped back.
      
      Fix the general case, by loading the driver in VEPA mode Until a
      VF or VMDq VSI is added. This way loopback on the Main VSI is
      turned off until needed and can resolve the issue of unnecessary
      reflection for users that do not have VF or VMDq VSIs setup.
      
      The driver must now coordinate the loopback setting for the Flow
      Director (FDIR) VSI to make sure it is in sync with the current
      VEB or VEPA mode setting.
      
      The user can still switch bridge modes from the bridge commands and
      choose to be in VEPA mode with VF VSIs. Because of hardware
      requirements, the call to switch to VEB mode when no VF/VMDqs are
      present will be rejected.
      
      NOTE: This patch uses BIT_ULL as that is preferred going forward,
      a followup patch in the lower priority queue to net-next will fix
      up the remaining 1 << usages.

      i40e/i40evf: Fix mixed size frags and linearization · 30520831
      Anjali Singhai Jain authored
      This patch fixes a bug where the i40e Tx queue will hang if this
      skb is passed to the driver.
      
      With mixed size fragments while using TSO there was a corner case
      where we needed to linearize but we were not. This was seen with
      iSCSI traffic and could be reproduced with a frag list that looks
      like this:
      
      num_frags = 17, gso_segs = 17, hdr_len = 66,
      skb_shinfo(skb)->gso_size = 1448
      size = 3002, j = 1, frag_size = 2936, num_frags = 17
      size = 4268, j = 1, frag_size = 4096, num_frags = 16
      size = 5534, j = 1, frag_size = 4096, num_frags = 15
      size = 5352, j = 1, frag_size = 4096, num_frags = 14
      size = 5170, j = 1, frag_size = 4096, num_frags = 13
      size = 3468, j = 1, frag_size = 2576, num_frags = 12
      size = 750, j = 1, frag_size = 112, num_frags = 11
      size = 862, j = 2, frag_size = 112, num_frags = 10
      size = 974, j = 3, frag_size = 112, num_frags = 9
      size = 1126, j = 4, frag_size = 152, num_frags = 8
      size = 1330, j = 5, frag_size = 204, num_frags = 7
      size = 1534, j = 6, frag_size = 204, num_frags = 6
      size = 356, j = 1, frag_size = 204, num_frags = 5
      size = 560, j = 2, frag_size = 204, num_frags = 4
      size = 764, j = 3, frag_size = 204, num_frags = 3
      size = 968, j = 4, frag_size = 204, num_frags = 2
      size = 1140, j = 5, frag_size = 172, num_frags = 1
      result: linearize = 0, j = 6

      Pull networking fixes from David Miller:
      
       1) Various VTI tunnel (mark handling, PMTU) bug fixes from Alexander
          Duyck and Steffen Klassert.
      
       2) Revert ethtool PHY query change, it wasn't correct.  The PHY address
          selected by the driver running the PHY to MAC connection decides
          what PHY address GET ethtool operations return information from.
      
       3) Fix handling of sequence number bits for encryption IV generation in
          ESP driver, from Herbert Xu.
      
       4) UDP can return -EAGAIN when we hit a bad checksum on receive, even
          when there are other packets in the receive queue which is wrong.
          Just respect the error returned from the generic socket recv
          datagram helper.  From Eric Dumazet.
      
       5) Fix BNA driver firmware loading on big-endian systems, from Ivan
          Vecera.
      
       6) Fix regression in that we were inheriting the congestion control of
          the listening socket for new connections, the intended behavior
          always was to use the default in this case.  From Neal Cardwell.

        It's very hard to hit; possible in the same conditions as the original
        bug, except that you need the skipped branch to contain all the
        remaining evictables, so that the d_walk()-calling loop in
        d_invalidate() decides there's nothing more to do and doesn't go for
        another pass - otherwise that next pass will sweep the sucker.
      
        So it's not too urgent, but seeing that the fix is obvious and the
        original commit has spread into all -stable branches..."
