      Pull networking fixes from David Miller:
      
       1) We've discovered a common error in several networking drivers, they
          put VLAN offload features into ->vlan_features, which would suggest
          that they support offloading 2 or more levels of VLAN encapsulation.
          Not only do these devices not do that, but we don't have the
          infrastructure yet to handle that at all.
      
          Fixes from Vlad Yasevich.
      
       2) Fix tcpdump crash with bridging and vlans, also from Vlad.
      
       3) Some MAINTAINERS updates for random32 and bonding.
      
       4) Fix late reseeds of prandom generator, from Sasha Levin.
      
       5) Bridge doesn't handle stacked vlans properly, fix from Toshiaki
          Makita.
      
       6) Fix deadlock in openvswitch, from Flavio Leitner.
      
       7) get_timewait4_sock() doesn't report delay times correctly, fix from
          Eric Dumazet.
      
       8) Duplicate address detection and addrconf verification need to run in
          contexts where RTNL can be obtained.  Move them to run from a
          workqueue.  From Hannes Frederic Sowa.
      
       9) Fix route refcount leaking in ip tunnels, from Pravin B Shelar.
      
      10) Don't return -EINTR from non-blocking recvmsg() on AF_UNIX sockets,
          from Eric Dumazet.

      ====================
      Audit all drivers for correct vlan_features.
      
      Some drivers set vlan acceleration features in vlan_features.  This causes
      issues with Q-in-Q/802.1ad configurations.
      
      Audit all the drivers for correct vlan_features.  Fix broken ones.
      Add a warning to vlan code to help catch future offenders.

      Some drivers incorrectly assign vlan acceleration features to
      vlan_features thus causing issues for Q-in-Q vlan configurations.
      Warn the user of such cases.

      For completeness, turn off vlan rx acceleration in vlan_features so
      that it doesn't show up on q-in-q setups.

      qlge: Do not propaged vlan tag offloads to vlans · f6d1ac4b
      Vlad Yasevich authored
      qlge driver turns off NETIF_F_HW_CTAG_FILTER, but forgets to
      turn off HW_CTAG_TX and HW_CTAG_RX on vlan devices.  With the
      current settings, q-in-q will only generate a single vlan header.
      Remember to mask off CTAG_TX and CTAG_RX features in vlan_features.

      bridge: Fix crash with vlan filtering and tcpdump · fc92f745
      Vlad Yasevich authored
      When the vlan filtering is enabled on the bridge, but
      the filter is not configured on the bridge device itself,
      running tcpdump on the bridge device will result in a
      an Oops with NULL pointer dereference.  The reason
      is that br_pass_frame_up() will bypass the vlan
      check because promisc flag is set.  It will then try
      to get the table pointer and process the packet based
      on the table.  Since the table pointer is NULL, we oops.
      Catch this special condition in br_handle_vlan().
