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.

2-part workaround for this hardware bug.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
Add detection and recovery code when the hardware returned opaque value
does not match the expected consumer index. Once the issue is detected,
we skip the processing of all RX and LRO/GRO packets. These completion
entries are discarded without sending the SKB to the stack and without
producing new buffers. The function will be reset from a workqueue.

There is a rare hardware bug that can cause a bad opaque value in the RX
or TPA completion. When this happens, the hardware may have used the
same buffer twice for 2 rx packets. In addition, the driver will also
crash later using the bad opaque as the index into the ring.
The rx opaque value is predictable and is always monotonically increasing.
The workaround is to keep track of the expected next opaque value and
compare it with the one returned by hardware during RX and TPA start
completions. If they miscompare, we will not process any more RX and
TPA completions and exit NAPI. We will then schedule a workqueue to
reset the function.
This patch adds the logic to keep track of the next rx consumer index.

Mellanox 100G mlx5 CQE compression
Introducing ConnectX-4 CQE (Completion Queue Entry) compression feature
for mlx5 etherent driver.
CQE Compressing reduces PCI overhead by coalescing and compressing multiple CQEs into a
single merged CQE. Successful compressing improves message rate especially for small packet
traffic.
CQE Compressing in details:
Instead of writing full CQEs to memory, multiple almost identical CQEs are merged and compressed.
Information that is shared between the CQEs is written once, regardless of the number of
compressed CQEs. In addition, only the unique information (small amount of bytes compared to
full CQE size) is written per CQE.
CQE Compression Block:
This block contains multiple compressed CQEs. CQE Compression Block contains a single copy
of CQEs properties which are shared between all the compressed CQEs (called Title, see below)
and multiple mini CQEs (CQEs in compressed form).
Title:
The Title holds information which is shared between all the compressed CQEs in the CQE Compression
Block. In each Compression Block there is only a single Title regardless of the number
of compressed CQEs.
Mini CQE:
A CQE in compressed form that holds some data needed to extract a single full CQE, for example
8 Bytes instead of 64 Bytes.
The shared information between all compressed CQEs, which belong to the same CQE Compression
Block called Title, is written once, and only the unique information in each compressed
CQE, for example 8 bytes, is written per compressed CQE, called mini CQE.
Since CQE Compression can add overhead to the software (CPU),
it will be only enabled on "weak/slow" PCI slots, where it can actually help.

More enabler patches for DSA probing
The complete set of patches for the reworked DSA probing is too big to
post as once. These subset contains some enablers which are easy to
review.
Eventually, the Marvell driver will instantiate its own internal MDIO
bus, rather than have the framework do it, thus allows devices on the
bus to be listed in the device tree. Initialize the main mutex as soon
as it is created, to avoid lifetime issues with the mdio bus.
A previous patch renamed all the DSA probe functions to make room for
a true device probe. However the recent merging of all the Marvell
switch drivers resulted in mv88e6xxx going back to the old probe
name. Rename it again, so we can have a driver probe function.
Add minimum support for the Marvell switch driver to probe as an MDIO
device, as well as an DSA driver. Later patches will then register
this device with the new DSA core framework.
Move the GPIO reset code out of the DSA code. Different drivers may
need different reset mechanisms, e.g. via a reset controller for
memory mapped devices. Don't clutter up the core with this. Let each
driver implement what it needs.
master_dev is no longer needed in the switch drivers, since they have
access to a device pointer from the probe function. Remove it.
Let the switch parse the eeprom length from its one device tree
node. This is required with the new binding when the central DSA
platform device no longer exists.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
A switch can export an attached EEPROM using the standard ethtool API.
However the switch itself cannot determine the size of the EEPROM, and
multiple sizes are allowed. Thus a device tree property is supported
to indicate the length of the EEPROM. Parse this property during
device probe, and implement a callback function to retrieve it.

net: vrf: Fixup PKTINFO to return enslaved device index
Applications such as OSPF and BFD need the original ingress device not
the VRF device; the latter can be derived from the former. To that end
move the packet intercept from an rx handler that is invoked by
__netif_receive_skb_core to the ipv4 and ipv6 receive processing.
IPv6 already saves the skb_iif to the control buffer in ipv6_rcv. Since
the skb->dev has not been switched the cb has the enslaved device. Make
the same happen for IPv4 by adding the skb_iif to inet_skb_parm and set
it in ipv4 code after clearing the skb control buffer similar to IPv6.
From there the pktinfo can just pull it from cb with the PKTINFO_SKB_CB

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).

The core_pct_busy field of struct sample actually contains the
average performace during the last sampling period (in percent)
and not the utilization of the core as suggested by its name
which is confusing.
For this reason, change the name of that field to core_avg_perf
and rename the function that computes its value accordingly.
Also notice that storing this value as percentage requires a costly
integer multiplication to be carried out in a hot path, so instead
store it as an "extended fixed point" value with more fraction bits
and update the code using it accordingly (it is better to change the
name of the field along with its meaning in one go than to make those
two changes separately, as that would likely lead to more
confusion).

Currently, in intel_pstate_clear_update_util_hook(), after
clearing the utilization update hook, we leverage
synchronize_sched() to deal with synchronization, which
is a little bit time-costly because synchronize_sched()
has to wait for all the CPUs to go through a grace period.
Actually, the synchronize_sched() is not necessary if the utilization
update hook has not been set for the given CPU yet, so make the driver
check if that's the case and avoid the synchronize_sched() call then.

ipgre (not gretap, that still correctly stays ARPHRD_ETHER) and reset
mac_header.

When using conntrack helpers from OVS, a common configuration is to
perform a lookup without specifying a helper, then go through a
firewalling policy, only to decide to attach a helper afterwards.
In this case, the initial lookup will cause a ct entry to be attached to
the skb, then the later commit with helper should attach the helper and
confirm the connection. However, the helper attachment has been missing.
If the user has enabled automatic helper attachment, then this issue
will be masked as it will be applied in init_conntrack(). It is also
masked if the action is executed from ovs_packet_cmd_execute() as that
will construct a fresh skb.
This patch fixes the issue by making an explicit call to try to assign
the helper if there is a discrepancy between the action's helper and the
current skb->nfct.

Replace 2 arguments (cnt and rtt) in the congestion control modules'
pkts_acked() function with a struct. This will allow adding more
information without having to modify existing congestion control
modules (tcp_nv in particular needs bytes in flight when packet
was sent).
As proposed by Neal Cardwell in his comments to the tcp_nv patch.

The x86 exception table sorting was changed in commit 29934b0fb8
("x86/extable: use generic search and sort routines") to use the arch
independent code in lib/extable.c. However, the patch was mangled
somehow on its way into the kernel from the last version posted at [1].
The committed version kind of attempted to incorporate the changes of
commit 548acf1923 ("x86/mm: Expand the exception table logic to allow
new handling options") as in _completely_ _ignoring_ the x86 specific
'handler' member of struct exception_table_entry. This effectively
broke the sorting as entries will only partly be swapped now.
Fortunately, the x86 Kconfig selects BUILDTIME_EXTABLE_SORT, so the
exception table doesn't need to be sorted at runtime. However, in case
that ever changes, we better not break the exception table sorting just
because of that.
[ Ard Biesheuvel points out that BUILDTIME_EXTABLE_SORT applies to the
core image only, but we still rely on the sorting routines for modules
in that case - Linus ]
Fix this by providing a swap_ex_entry_fixup() macro that takes care of
the 'handler' member.

A bunch of small driver specific fixes that have come up, none of them
remarkable in themselves. One fixes a regression introduced in the
merge window and another two are targetted at stable.
