Geneve: Add support for tunnel metadata mode
Following patches adds support for Geneve tunnel metadata
mode. OVS can make use of Geneve net-device with tunnel
metadata API from kernel.
This also allows us to consolidate Geneve implementation
from two kernel modules geneve_core and geneve to single
geneve module. geneve_core module was targeted to share
Geneve encap and decap code between Geneve netdevice and
OVS Geneve tunnel implementation, Since OVS no longer
needs these API, Geneve code can be consolidated into
single geneve module.
v3-v4:
- Drop NETIF_F_NETNS_LOCAL feature.
- Fix geneve device newlink check
v2-v3:
- make tunnel medata device and regular device mutually exclusive.
- Fix Kconfig dependency for Geneve.
- Fix dst-port netlink encoding.
- drop changelink patch.

For classifiers getting invoked via tc_classify(), we always need an
extra function call into tc_classify_compat(), as both are being
exported as symbols and tc_classify() itself doesn't do much except
handling of reclassifications when tp->classify() returned with
TC_ACT_RECLASSIFY.
CBQ and ATM are the only qdiscs that directly call into tc_classify_compat(),
all others use tc_classify(). When tc actions are being configured
out in the kernel, tc_classify() effectively does nothing besides
delegating.
We could spare this layer and consolidate both functions. pktgen on
single CPU constantly pushing skbs directly into the netif_receive_skb()
path with a dummy classifier on ingress qdisc attached, improves
slightly from 22.3Mpps to 23.1Mpps.

Intel Wired LAN Driver Updates 2015-08-26
This series contains updates to i40e and i40evf only.
Anjali provides a fix for i40e where the part is not receiving multicast
or VLAN tagged packets when in promiscuous mode. This can occur when a
software bridge is created on top of the device. Fixed the legacy and MSI
interrupt mode in the driver, which was non-existent before since we
were assuming MSIX was the only mode that the driver ran in. Fixed the
i40evf driver, where the wrong defines were getting used in the VF
driver.
Mitch fixes a sparse warning about comparing __le16 to u16 so use
le16_to_cpu() to resolve the warning. Also fixed a dyslexic spelling
of invalid.
Shannon adds port.crc_errors to receive CRC error counter, since it
is a receive counter.
Catherine provides a fix to move the stopping of the service task and
flow director to i40e_shutdown() instead of i40e_suspend().
Greg fixes the ethtool offline diagnostic with netqueues, which just need
to be treated the same as virtual functions when someone wants to run the
ethtool offline diagnostic test. Also fixed up code comments for the
i40e ethtool diagnostic test function. Cleans up redundant and unneeded
messages, since the kernel notifies all VXLAN capable registered drivers,
so no need to log this.
Neerav adds the ability to update statistics per VEB per traffic class
and dump it via ethtool.
Jingjing adds support for virtual channel offload to support receive
polling mode in the VF driver.
v2: dropped patch which added helper functions into a header, feedback from
David Miller was to make the functions constant to reduce the driver
footprint, so remove the patch while Anjali works on making the requested
changes.

The goal of this series is to allow OVS to send packets through the Linux

This version addresses the feedback from v5, primarily checking the behaviour
is correct with different configurations such as disabling
CONFIG_OPENVSWITCH_CONNTRACK or disabling individual conntrack features like
connlabels.

Add support for using conntrack helpers to assist protocol detection.
The new OVS_CT_ATTR_HELPER attribute of the CT action specifies a helper
to be used for this connection. If no helper is specified, then helpers
will be automatically applied as per the sysctl configuration of
net.netfilter.nf_conntrack_helper.
The helper may be specified as part of the conntrack action, eg:
ct(helper=ftp). Initial packets for related connections should be
committed to allow later packets for the flow to be considered
established.
Example ovs-ofctl flows allowing FTP connections from ports 1->2:
in_port=1,tcp,action=ct(helper=ftp,commit),2
in_port=2,tcp,ct_state=-trk,action=ct(recirc)
in_port=2,tcp,ct_state=+trk-new+est,action=1

Expose the kernel connection tracker via OVS. Userspace components can
make use of the CT action to populate the connection state (ct_state)
field for a flow. This state can be subsequently matched.
Exposed connection states are OVS_CS_F_*:
- NEW (0x01) - Beginning of a new connection.
- ESTABLISHED (0x02) - Part of an existing connection.
- RELATED (0x04) - Related to an established connection.
- INVALID (0x20) - Could not track the connection for this packet.
- REPLY_DIR (0x40) - This packet is in the reply direction for the flow.
- TRACKED (0x80) - This packet has been sent through conntrack.
When the CT action is executed by itself, it will send the packet
through the connection tracker and populate the ct_state field with one
or more of the connection state flags above. The CT action will always
set the TRACKED bit.
When the COMMIT flag is passed to the conntrack action, this specifies
that information about the connection should be stored. This allows
subsequent packets for the same (or related) connections to be
correlated with this connection. Sending subsequent packets for the
connection through conntrack allows the connection tracker to consider
the packets as ESTABLISHED, RELATED, and/or REPLY_DIR.
The CT action may optionally take a zone to track the flow within. This
allows connections with the same 5-tuple to be kept logically separate
from connections in other zones. If the zone is specified, then the
"ct_zone" match field will be subsequently populated with the zone id.
IP fragments are handled by transparently assembling them as part of the
CT action. The maximum received unit (MRU) size is tracked so that
refragmentation can occur during output.
IP frag handling contributed by Andy Zhou.
Based on original design by Justin Pettit.

ACPI 6.0 NFIT Memory Device State Flags in Table 5-129 defines
NVDIMM status as follows. These bits indicate multiple info,
such as failures, pending event, and capability.
Bit [0] set to 1 to indicate that the previous SAVE to the
Memory Device failed.
Bit [1] set to 1 to indicate that the last RESTORE from the
Memory Device failed.
Bit [2] set to 1 to indicate that platform flush of data to
Memory Device failed. As a result, the restored data content
may be inconsistent even if SAVE and RESTORE do not indicate
failure.
Bit [3] set to 1 to indicate that the Memory Device is observed
to be not armed prior to OSPM hand off. A Memory Device is
considered armed if it is able to accept persistent writes.
Bit [4] set to 1 to indicate that the Memory Device observed
SMART and health events prior to OSPM handoff.
/sys/bus/nd/devices/nmemX/nfit/flags shows this flags info.
The output strings associated with the bits are "save", "restore",
"smart", etc., which can be confusing as they may be interpreted
as positive status, i.e. save succeeded.
Change also the dev_info() message in acpi_nfit_register_dimms()
