This adds support for PF control over the VF vlan configuration.
I.e., `ip link ... vf <x> vlan <vid>' should now be supported.
1. <vid> != 0 => VF receives [unknowingly] only traffic tagged by

2. <vid> == 0 ==> Remove the pvid configuration, reverting to previous.

As the VF infrastructure is supposed to offer backward/forward
compatibility, the various types associated with VF<->PF communication
should be aligned across all various platforms that support IOV
on our family of adapters.
This adds a couple of currently missing values, specifically aligning
the enum for the various TLVs possible in the communication between them.
It then adds the PF implementation for some of those missing VF requests.
This support isn't really necessary for the Linux VF as those VFs aren't
requiring it [at least today], but are required by VFs running on other
OSes. LRO is an example of one such configuration.

Up to this point, VF and PF communication always originates from VF.
As a result, VF cannot be notified of any async changes, and specifically
cannot be informed of the current link state.
This introduces the bulletin board, the mechanism through which the PF
is going to communicate async notifications back to the VF. basically,
it's a well-defined structure agreed by both PF and VF which the VF would
continuously poll and into which the PF would DMA messages when needed.
[Bulletin board is actually allocated and communicated in previous patches
but never before used]
Based on the bulletin infrastructure, the VF can query its link status
and receive said async carrier changes.

This adds sufficient changes to allow VFs l2-configuration flows to work.
While the fastpath of the VF and the PF are meant to be exactly the same,
the configuration of the VF is done by the PF.
This diverges all VF-related configuration flows that originate from a VF,
making them pass through the VF->PF channel and adding sufficient logic
on the PF side to support them.

While previous patches have already added the necessary logic to probe
VFs as well as enabling them in the HW, this patch adds the ability to
support VF FLR & SRIOV disable.
It then wraps both flows together into the first IOV callback to be
provided to the protocol driver - `configure'. This would later to be used
to enable and disable SRIOV in the adapter.

This adds the qed VFs for the first time -
The vfs are limited functions, with a very different PCI bar structure
[when compared with PFs] to better impose the related security demands
associated with them.
This patch includes the logic neccesary to allow VFs to successfully probe
[without actually adding the ability to enable iov].
This includes diverging all the flows that would occur as part of the pci
probe of the driver, preventing VF from accessing registers/memories it
can't and instead utilize the VF->PF channel to query the PF for needed
information.

Communication between VF and PF is based on a dedicated HW channel;
VF will prepare a messge, and by signaling the HW the PF would get a
notification of that message existance. The PF would then copy the
message, process it and DMA an answer back to the VF as a response.
The messages themselves are TLV-based - allowing easier backward/forward
compatibility.
This patch adds the infrastructure of the channel on the PF side -
starting with the arrival of the notification and ending with DMAing
the response back to the VF.
It also adds a dummy-response as reference, as it only lays the
groundwork of the communication; it doesn't really add support of any
actual messages.

====================
NFC 4.7 pull request
This is the first NFC pull request for 4.7. With this one we
mainly have:
- Support for NXP's pn532 NFC chipset. The pn532 is based on the same
microcontroller as the pn533, but it talks to the host through i2c
instead of USB. By separating the pn533 driver into core and PHY
parts, we can not add the i2c layer and support the pn532 chipset.
- Support for NCI's loopback mode. This is a testing mode where each
packet received by the NFCC is sent back to the DH, allowing the
host to test that the controller can receive and send data.
- A few ACPI related fixes for the STMicro drivers, in order to match
the device tree naming scheme.
- A bunch of cleanups for the st-nci and the st21nfca STMicro drivers.

A switch can export an attached EEPROM using the standard ethtool API.
However the switch itself cannot determine the size of the EEPROM, and

Currently the VRF driver uses the rx_handler to switch the skb device
to the VRF device. Switching the dev prior to the ip / ipv6 layer
means the VRF driver has to duplicate IP/IPv6 processing which adds
overhead and makes features such as retaining the ingress device index
more complicated than necessary.
This patch moves the hook to the L3 layer just after the first NF_HOOK
for PRE_ROUTING. This location makes exposing the original ingress device
trivial (next patch) and allows adding other NF_HOOKs to the VRF driver
in the future.
dev_queue_xmit_nit is exported so that the VRF driver can cycle the skb
with the switched device through the packet taps to maintain current
behavior (tcpdump can be used on either the vrf device or the enslaved
devices).

This is an initial implementation of a netdev driver for GTP datapath
(GTP-U) v0 and v1, according to the GSM TS 09.60 and 3GPP TS 29.060
standards. This tunneling protocol is used to prevent subscribers from
accessing mobile carrier core network infrastructure.
This implementation requires a GGSN userspace daemon that implements the
signaling protocol (GTP-C), such as OpenGGSN [1]. This userspace daemon
updates the PDP context database that represents active subscriber
sessions through a genetlink interface.
For more context on this tunneling protocol, you can check the slides
that were presented during the NetDev 1.1 [2].
Only IPv4 is supported at this time.

Allow udp and raw sockets to send by oif that is an enslaved interface
versus the l3mdev/VRF device. For example, this allows BFD to use ifindex
from IP_PKTINFO on a receive to send a response without the need to
convert to the VRF index. It also allows ping and ping6 to work when
specifying an enslaved interface (e.g., ping -I swp1 <ip>) which is
a natural use case.
