Quoth David:

1) GRO MAC header comparisons were ethernet specific, breaking other
   link types.  This required a multi-faceted fix to cure the originally
   noted case (Infiniband), because IPoIB was lying about it's actual
   hard header length.  Thanks to Eric Dumazet, Roland Dreier, and
   others.

2) Fix build failure when INET_UDP_DIAG is built in and ipv6 is modular.
   From Anisse Astier.

3) Off by ones and other bug fixes in netprio_cgroup from Neil Horman.

4) ipv4 TCP reset generation needs to respect any network interface
   binding from the socket, otherwise route lookups might give a
   different result than all the other segments received.  From Shawn
   Lu.

5) Fix unintended regression in ipv4 proxy ARP responses, from Thomas
   Graf.

6) Fix SKB under-allocation bug in sh_eth, from Yoshihiro Shimoda.

7) Revert skge PCI mapping changes that are causing crashes for some
   folks, from Stephen Hemminger.

8) IPV4 route lookups fill in the wildcarded fields of the given flow
   lookup key passed in, which is fine most of the time as this is
   exactly what the caller's want.  However there are a few cases that
   want to retain the original flow key values afterwards, so handle
   those cases properly.  Fix from Julian Anastasov.

9) IGB/IXGBE VF lookup bug fixes from Greg Rose.

10) Properly null terminate filename passed to ethtool flash device
    method, from Ben Hutchings.

11) S3 resume fix in via-velocity from David Lv.

12) Fix double SKB free during xmit failure in CAIF, from Dmitry
    Tarnyagin.

Commit a0417fa3a18a ("net: Make qdisc_skb_cb upper size bound
explicit.") made it possible for a netdev driver to use skb->cb
between its header_ops.create method and its .ndo_start_xmit
method.  Use this in ipoib_hard_header() to stash away the LL address
(GID + QPN), instead of the "ipoib_pseudoheader" hack.  This allows
IPoIB to stop lying about its hard_header_len, which will let us fix
the L2 check for GRO.

In the current code, vendor-specific MADs (e.g with the FDR-10
attribute) are silently dropped by the driver, resulting in timeouts
at the sending side and inability to query/configure the relevant
feature.  However, the ConnectX firmware is able to handle such MADs.
For unsupported attributes, the firmware returns a GET_RESPONSE MAD
containing an error status.

For example, for a FDR-10 node with LID 11:

    # ibstat mlx4_0 1

    CA: 'mlx4_0'
    Port 1:
    State: Active
    Physical state: LinkUp
    Rate: 40 (FDR10)
    Base lid: 11
    LMC: 0
    SM lid: 24
    Capability mask: 0x02514868
    Port GUID: 0x0002c903002e65d1
    Link layer: InfiniBand

Extended Port Query (EPI) vendor mad timeouts before the patch:

    # smpquery MEPI 11 -d

    ibwarn: [4196] smp_query_via: attr 0xff90 mod 0x0 route Lid 11
    ibwarn: [4196] _do_madrpc: retry 1 (timeout 1000 ms)
    ibwarn: [4196] _do_madrpc: retry 2 (timeout 1000 ms)
    ibwarn: [4196] _do_madrpc: timeout after 3 retries, 3000 ms
    ibwarn: [4196] mad_rpc: _do_madrpc failed; dport (Lid 11)
    smpquery: iberror: [pid 4196] main: failed: operation EPI: ext port info query failed

EPI query works OK with the patch:

    # smpquery MEPI 11 -d

    ibwarn: [6548] smp_query_via: attr 0xff90 mod 0x0 route Lid 11
    ibwarn: [6548] mad_rpc: data offs 64 sz 64
