Add common library module(libcxgb.ko) for
Chelsio drivers to remove duplicate code.

Code for iSCSI DDP Page Pod Manager is moved
from cxgb4.ko to libcxgb.ko. Earlier only cxgbit.ko
was using this code, now cxgb3i and cxgb4i will
also use common Page Pod manager code.

In future this module will have common connection
management and hardware specific code that can be
shared by multiple Chelsio drivers.

When using an IPoIB bond currently only active-backup mode is a valid
use case and this commit strengthens it.

Since commit 2ab82852 ("net/bonding: Enable bonding to enslave
netdevices not supporting set_mac_address()") was introduced till
4.7-rc1, IPoIB didn't support the set_mac_address ndo, and hence the
fail over mac policy always applied to IPoIB bonds.

With the introduction of commit 492a7e67 ("IB/IPoIB: Allow setting
the device address"), that doesn't hold and practically IPoIB bonds are
broken as of that. To fix it, lets go to fail over mac if the device
doesn't support the ndo OR this is IPoIB device.

As a by-product, this commit also prevents a stack corruption which
occurred when trying to copy 20 bytes (IPoIB) device address
to a sockaddr struct that has only 16 bytes of storage.

mlxsw: implement port mirroring offload

This patchset introduces tc matchall classifier and its offload
to Spectrum hardware. In combination with mirred action, defined port mirroring
setup is offloaded by mlxsw/spectrum driver.

The commands used for creating mirror ports:

tc qdisc  add dev eth25 handle ffff: ingress
tc filter add dev eth25 parent ffff:            \
        matchall skip_sw                        \
        action mirred egress mirror             \
        dev eth27

tc qdisc add dev eth25 handle 1: root prio
tc filter add dev eth25 parent 1:               \
        matchall skip_sw                        \
        action mirred egress mirror             \
        dev eth27

These patches contain:
 - Resource query implementation
 - Hardware port mirorring support for spectrum.
 - Definition of the matchall traffic classifier.
 - General support for hw-offloading for that classifier.
 - Specific spectrum implementaion for matchall offloading.

This patch offloads port mirroring directives to hw using the matchall TC
with action mirror. It includes both the implementation of the
ndo_setup_tc function for the spectrum driver and the spectrum hardware
offload configuration code.

The hardware offload code is basically two new functions which are capable
of adding and removing a new mirror ports pair. It is done using the MPAT,
MPAR and SBIB registers:
 - A new Switch-Port Analyzer (SPAN) entry is added using MPAT to the 'to'
   port.
 - The 'to' port is bound to the SPAN entry using MPAR register.
 - In case of egress SPAN, the 'to' port gets a new internal shared
   buffer using SBIB register.

In addition, a new database was added to the mlxsw_sp struct to store all
the SPAN entries and their bound ports list. The number of supported SPAN
entries is determined by resource query.

The firmware in several ZTE devices (at least the MF823/831/910
modems/mifis) use OS fingerprinting to determine which type of device to
export. In addition, these devices export a REST API which can be used to
control the type of device. So far, on Linux, the devices have been seen as
RNDIS or CDC Ether.

When CDC Ether is used, devices of the same type are, as with RNDIS,
exported with the same, bogus random MAC address. In addition, the devices
(at least on all firmware revisions I have found) use the bogus MAC when
sending traffic routed from external networks. And as a final feature, the
devices sometimes export the link state incorrectly. There are also
references online to several other ZTE devices displaying this behavior,
with several different PIDs and MAC addresses.

This patch tries to improve the handling of ZTE devices by doing the
following:

* Create a new driver_info-struct that is used by ZTE devices that do not
have an explicit entry in the product table. This struct is the same as the
default cdc_ether driver info, but a new bind- and an rx_fixup-function
have been added.

* In the new bind function, we check if we have read a random MAC from the
device. If we have, then we generate a new random MAC address. This will
ensure that all devices get a unique MAC.

* The rx_fixup-function replaces the destination MAC address in the skb
with that of the device. I have not seen a revision of these devices that
behaves correctly (i.e., sets the right destination MAC), so I chose not to
do any comparison with for example the known, bogus addresses.

* The MF823/MF832/MF910 sometimes export cdc carrier on twice on connect
(the correct behavior is off then on). Work around this by manually setting
carrier to off if an on-notification is received and the NOCARRIER-bit is
not set.

This change will affect all devices, but it should take care of similar
mistakes made by other manufacturers. I tried to think of/look/test for
problems/regressions that could be introduced by this behavior, but could
not find any. However, my familiarity with this code path is not that
great, so there could be something I have overlooked.

I have tested this patch with multiple revisions of all three devices, and
they behave as expected. In other words, they all got a valid, random MAC,
the correct operational state and I can receive/sent traffic without
problems. I also tested with some other cdc_ether devices I have and did
not find any problems/regressions caused by the two general changes.

v3->v4:
* Forgot to remove unused variables, sorry about that (thanks David
Miller).

v2->v3:
* I had forgot to remove the random MAC generation from usbnet_cdc_bind()
(thanks Oliver).
* Rework logic in the ZTE bind-function a bit.

v1->v2:
* Only generate random MAC for ZTE devices (thanks Oliver Neukum).
* Set random MAC and do RX fixup for all ZTE devices that do not have a
product-entry, as the bogus MAC have been seen on devices with several
different PIDs/MAC addresses. In other words, it seems to be the default
behavior of ZTE CDC Ether devices (thanks Lars Melin).

Netfilter/IPVS updates for net-next

The following patchset contains Netfilter/IPVS updates for net-next,
they are:

1) Count pre-established connections as active in "least connection"
   schedulers such that pre-established connections to avoid overloading
   backend servers on peak demands, from Michal Kubecek via Simon Horman.

2) Address a race condition when resizing the conntrack table by caching
   the bucket size when fulling iterating over the hashtable in these
   three possible scenarios: 1) dump via /proc/net/nf_conntrack,
   2) unlinking userspace helper and 3) unlinking custom conntrack timeout.
   From Liping Zhang.

3) Revisit early_drop() path to perform lockless traversal on conntrack
   eviction under stress, use del_timer() as synchronization point to
   avoid two CPUs evicting the same entry, from Florian Westphal.

4) Move NAT hlist_head to nf_conn object, this simplifies the existing
   NAT extension and it doesn't increase size since recent patches to
   align nf_conn, from Florian.

5) Use rhashtable for the by-source NAT hashtable, also from Florian.

6) Don't allow --physdev-is-out from OUTPUT chain, just like
   --physdev-out is not either, from Hangbin Liu.

7) Automagically set on nf_conntrack counters if the user tries to
   match ct bytes/packets from nftables, from Liping Zhang.

8) Remove possible_net_t fields in nf_tables set objects since we just
   simply pass the net pointer to the backend set type implementations.

9) Fix possible off-by-one in h323, from Toby DiPasquale.

10) early_drop() may be called from ctnetlink patch, so we must hold
    rcu read size lock from them too, this amends Florian's patch #3
    coming in this batch, from Liping Zhang.

11) Use binary search to validate jump offset in x_tables, this
    addresses the O(n!) validation that was introduced recently
    resolve security issues with unpriviledge namespaces, from Florian.

12) Fix reference leak to connlabel in error path of nft_ct, from Zhang.

13) Three updates for nft_log: Fix log prefix leak in error path. Bail
    out on loglevel larger than debug in nft_log and set on the new
    NF_LOG_F_COPY_LEN flag when snaplen is specified. Again from Zhang.

14) Allow to filter rule dumps in nf_tables based on table and chain
    names.

15) Simplify connlabel to always use 128 bits to store labels and
    get rid of unused function in xt_connlabel, from Florian.

16) Replace set_expect_timeout() by mod_timer() from the h323 conntrack
    helper, by Gao Feng.

17) Put back x_tables module reference in nft_compat on error, from
    Liping Zhang.

18) Add a reference count to the x_tables extensions cache in
    nft_compat, so we can remove them when unused and avoid a crash
    if the extensions are rmmod, again from Zhang.

  specific-method) format that the platform firmware implements for
  nvdimm devices.  We initially fixed a regression in probing the QEMU
  DSM implementation by making acpi_check_dsm() tolerant of the way QEMU
  reports the "0 DSMs supported" condition.

  However, that broke HPE platforms since that tolerance caused the
  driver to mistakenly match the 1-zero-byte response those platforms
  give to "unknown" commands.  Instead, we simply make the driver
  tolerant of not finding any supported DSMs.  This has been tested to
  work with both QEMU and HPE platforms.

  This commit has appeared in a -next release with no reported issues"

 "Compile problem fix for Tegra,

  Sorry to send this in the last minute but Ingo says this build failure
  is very prominent so I'm not going to wait for v4.7 before sending it.

  It is a case of COMPILE_TEST causing more problems than it solves and
  I'm already swearing about me shooting myself in the foot with that

With this command sequence:

  modprobe plip
  modprobe pps_parport
  rmmod pps_parport

the partport_pps modules causes this crash:

  BUG: unable to handle kernel NULL pointer dereference at (null)
  IP: parport_detach+0x1d/0x60 [pps_parport]
  Oops: 0000 [#1] SMP
  ...
  Call Trace:
    parport_unregister_driver+0x65/0xc0 [parport]
    SyS_delete_module+0x187/0x210

The sequence that builds up to this is:

 1) plip is loaded and takes the parport device for exclusive use:

    plip0: Parallel port at 0x378, using IRQ 7.

 2) pps_parport then fails to grab the device:

    pps_parport: parallel port PPS client
    parport0: cannot grant exclusive access for device pps_parport
    pps_parport: couldn't register with parport0

 3) rmmod of pps_parport is then killed because it tries to access
    pardev->name, but pardev (taken from port->cad) is NULL.

So add a check for NULL in the test there too.
