[David Miller <davem@davemloft.net>]

1) Stretch ACKs can kill performance with Reno and CUBIC congestion control,
   largely due to LRO and GRO.  Fix from Neal Cardwell.

2) Fix userland breakage because we accidently emit zero length netlink
   messages from the bridging code.  From Roopa Prabhu.

3) Carry handling in generic csum_tcpudp_nofold is broken, fix from
   Karl Beldan.

4) Remove bogus dev_set_net() calls from CAIF driver, from Nicolas
   Dichtel.

5) Make sure PPP deflation never returns a length greater then the
   output buffer, otherwise we overflow and trigger skb_over_panic().
   Fix from Florian Westphal.

6) COSA driver needs VIRT_TO_BUS Kconfig dependencies, from Arnd
   Bergmann.

7) Don't increase route cached MTU on datagram too big ICMPs.
   From Li Wei.

8) Fix error path leaks in nf_tables, from Pablo Neira Ayuso.

9) Fix bitmask handling regression in netlink that broke things
   like acpi userland tools.  From Pablo Neira Ayuso.

10) Wrong header pointer passed to param_type2af() in SCTP code,
    from Saran Maruti Ramanara.

11) Stacked vlans not handled correctly by vlan_get_protocol(), from
    Toshiaki Makita.

12) Add missing DMA memory barrier to xgene driver, from Iyappan
    Subramanian.

13) Fix crash in rate estimators, from Eric Dumazet.

14) We've been adding various workarounds, one after another, for
    the change which added the per-net tcp_sock.  It was meant to
    reduce socket contention but added lots of problems.

    Reduce this instead to a proper per-cpu socket and that rids
    us of all the daemons.

    From Eric Dumazet.

15) Fix memory corruption and OOPS in mlx4 driver, from Jack
    Morgenstein.

16) When we disabled UFO in the virtio_net device, it introduces some
    serious performance regressions.  The orignal problem was IPV6
    fragment ID generation, so fix that properly instead.  From Vlad
    Yasevich.

17) sr9700 driver build breaks on xtensa because it defines macros
    with the same name as those used by the arch code.  Use more
    unique names.  From Chen Gang.

18) Fix endianness in new virio 1.0 mode of the vhost net driver,
    from Michael S. Tsirkin.

19) Several sysctls were setting the maxlen attribute incorrectly,
    from Sasha Levin.

20) Don't accept an FQ scheduler quantum of zero, that leads to
    crashes.  From Kenneth Klette Jonassen.

21) Fix dumping of non-existing actions in the packet scheduler
    classifier.  From Ignacy Gawędzki.

22) Return the write work_done value when doing TX work in the qlcnic
    driver.

23) ip6gre_err accesses the info field with the wrong endianness,
    from Sabrina Dubroca.
