      openvswitch: fix mis-ordered comment lines for ovs_skb_cb · 52427fa0
      Daniel Axtens authored
      
      
      I was trying to wrap my head around meaning of mru, and realised
      that the second line of the comment defining it had somehow
      ended up after the line defining cutlen, leading to much confusion.
      
      Reorder the lines to make sense.

      wireless-drivers-next patches for 4.13
      
      Last minute changes to get new hardware and firmware support for

      patches for ieee80211.h and nl80211 as Johannes is away.
      
      Major changes:
      
      iwlwifi
      
      * some important fixes for 9000 HW
      
      * support for version 30 of the FW API for 8000 and 9000 series
      
      * a few new PCI IDs for 9000 series
      
      * reorganization of common files

      net: core: Fix slab-out-of-bounds in netdev_stats_to_stats64 · 9af9959e
      Alban Browaeys authored
      commit 9256645a
      
       ("net/core: relax BUILD_BUG_ON in
      netdev_stats_to_stats64") made an attempt to read beyond
      the size of the source a possibility.
      
      Fix to only copy src size to dest. As dest might be bigger than src.

      Pointer hdr in netxen_setup_minidump() is set but never used, thus
      should be removed.

      It's not a good idea to add the same hlist_node to two different hash lists.
      This leads to various hard to debug memory corruptions.
