   4) SMC bug fixes from Karsten Graul, YueHaibing, and Ursula Braun.

   5) Fix TX done race in mvpp2, from Antoine Tenart.

   6) ipv6 metrics leak, from Wei Wang.

   7) Adjust firmware version requirements in mlxsw, from Petr Machata.

   8) Fix autonegotiation on resume in r8169, from Heiner Kallweit.

   9) Fixed missing entries when dumping /proc/net/if_inet6, from Jeff
      Barnhill.

   10) Fix double free in devlink, from Dan Carpenter.

   11) Fix ethtool regression from UFO feature removal, from Maciej
       Żenczykowski.

   12) Fix drivers that have a ndo_poll_controller() that captures the
       cpu entirely on loaded hosts by trying to drain all rx and tx
       queues, from Eric Dumazet.

   13) Fix memory corruption with jumbo frames in aquantia driver, from
       Friedemann Gerold."
