efx_default_channel_want_txqs() is only used in efx.c, while
efx_ptp_want_txqs() and efx_ptp_channel_type (a struct) are only used
in ptp.c. In all cases these symbols should be static.

====================
40GbE Intel Wired LAN Driver Updates 2018-01-26
This series contains updates to i40e and i40evf.
Michal updates the driver to pass critical errors from the firmware to
the caller.
Patryk fixes an issue of creating multiple identical filters with the
same location, by simply moving the functions so that we remove the
existing filter and then add the new filter.
Paweł adds back in the ability to turn off offloads when VLAN is set for
the VF driver. Fixed an issue where the number of TC queue pairs was
exceeding MSI-X vectors count, causing messages about invalid TC mapping
and wrong selected Tx queue.
Alex cleans up the i40e/i40evf_set_itr_per_queue() by dropping all the
unneeded pointer chases. Puts to use the reg_idx value, which was going
unused, so that we can avoid having to compute the vector every time
throughout the driver.
Upasana enable the driver to display LLDP information on the vSphere Web
Client by exposing DCB parameters.
Alice converts our flags from 32 to 64 bit size, since we have added
more flags.
Dave implements a private ethtool flag to disable the processing of LLDP
packets by the firmware, so that the firmware will not consume LLDPDU
and cause them to be sent up the stack.
Alan adds a mechanism for detecting/storing the flag for processing of
LLDP packets by the firmware, so that its current state is persistent
across reboots/reloads of the driver.
Avinash fixes kdump with i40e due to resource constraints. We were
enabling VMDq and iWARP when we just have a single CPU, which was
starving kdump for the lack of IRQs.
Jake adds support to program the fragmented IPv4 input set PCTYPE.
Fixed the reported masks to properly report that the entire field is
masked, since we had accidentally swapped the mask values for the IPv4
addresses with the L4 port numbers.

The ib_write_umad() is protected by taking the umad file mutex.
However, it accesses file->port->ib_dev -- which is protected only by the
port's mutex (field file_mutex).
The ib_umad_remove_one() calls ib_umad_kill_port() which sets
port->ib_dev to NULL under the port mutex (NOT the file mutex).
It then sets the mad agent to "dead" under the umad file mutex.
This is a race condition -- because there is a window where
port->ib_dev is NULL, while the agent is not "dead".
As a result, we saw stack traces like:

10GbE Intel Wired LAN Driver Updates 2018-01-26
This series contains updates to ixgbe and ixgbevf.
Emil updates ixgbevf to match ixgbe functionality, starting with the
consolidating of functions that represent logical steps in the receive
process so we can later update them more easily. Updated ixgbevf to
only synchronize the length of the frame, which will typically be the
MTU or smaller. Updated the VF driver to use the length of the packet
instead of the DD status bit to determine if a new descriptor is ready
to be processed, which saves on reads and we can save time on
initialization. Added support for DMA_ATTR_SKIP_CPU_SYNC/WEAK_ORDERING
to help improve performance on some platforms. Updated the VF driver to
do bulk updates of the page reference count instead of just incrementing
it by one reference at a time. Updated the VF driver to only go through
the region of the receive ring that was designated to be cleaned up,
rather than process the entire ring.
Colin Ian King adds the use of ARRAY_SIZE() on various arrays.
Miroslav Lichvar fixes an issue where ethtool was reporting timestamping
filters unsupported for X550, which is incorrect.
Paul adds support for reporting 5G link speed for some devices.
Dan Carpenter fixes a typo where && was used when it should have been
||.

Calling fan related SMM functions implemented by Dell BIOS firmware on Dell

Unfortunately, it is unlikely for Dell to fix this since the machine

According to the OPAL docs:
skiboot-5.2.5/doc/opal-api/opal-rtc-read-3.txt
skiboot-5.2.5/doc/opal-api/opal-rtc-write-4.txt
OPAL_HARDWARE may be returned from OPAL_RTC_READ or OPAL_RTC_WRITE and
this indicates either a transient or permanent error.
Prior to this patch, Linux was not dealing with OPAL_HARDWARE being a
permanent error particularly well, in that you could end up in a busy
loop.
This was not too hard to trigger on an AMI BMC based OpenPOWER machine
doing a continuous "ipmitool mc reset cold" to the BMC, the result of
that being that we'd get stuck in an infinite loop in
opal_get_rtc_time().
We now retry a few times before returning the error higher up the
stack.

The USB port 1 clock gate control has an inversed polarity
from all the other clock gates in the chip. This makes the
aspeed_clk_{enable,disable} functions honor the flag
CLK_GATE_SET_TO_DISABLE and set that flag appropriately
so it's set for all clocks except USB port 1.

The majority of the clocks in the system are gates paired with a reset
controller that holds the IP in reset.
This borrows from clk_hw_register_gate, but registers two 'gates', one
to control the clock enable register and the other to control the reset
IP. This allows us to enforce the ordering:
1. Place IP in reset
2. Enable clock
3. Delay
4. Release reset
There are some gates that do not have an associated reset; these are
handled by using -1 as the index for the reset.

SMBIOS 3.0.0 Specification introduced new Chassis Types field values for
2-in-1 devices like tablets, convertibles and detachables. Dell's
Inspiron 2-in-1 and XPS 2-in-1 fall into this category and they have to
be added to the DMI whitelist, so rfkill and backlight can be controlled
for them as for other laptops.

The interrupt message number is the first 5 bits, but the driver was
masking only the first 4 bits. Fix that by using the existing

The "Determination of DPC Control" implementation note in PCIe r4.0, sec
6.1.10, recommends the operating system always link DPC control to the
control of AER, as the two functionalities are strongly connected.
To avoid conflicts over whether platform firmware or the OS controls DPC,
enable DPC only if AER is enabled in the OS, and the device's error
handling does not have firmware-first AER handling.

This patch suppresses the message about invalid TC mapping and wrong
selected TX queue. The root cause of this bug was setting too many
TC queue pairs on huge multiprocessor machines. When quantity of the
TC queue pairs is exceeding MSI-X vectors count then TX queue number
can be selected beyond actual TX queues amount.

The drivers for i40e and i40evf had a reg_idx value stored in the q_vector
that was going completely unused. I can only assume this was copied over
from ixgbe and nobody knew how to use it.
I'm going to make use of the value to avoid having to compute the vector
and thus the register index for multiple paths throughout the drivers.

In commit 36777d9fa24c ("i40e: check current configured input set when
adding ntuple filters") some code was added to report the input set
mask for a given filter when reporting it to the user.
This code is necessary so that the reported filter correctly displays
that it is or is not masking certain fields.
Unfortunately the code was incorrect. Development error accidentally
swapped the mask values for the IPv4 addresses with the L4 port numbers.
The port numbers are only 16bits wide while IPv4 addresses are 32 bits.
Unfortunately we assigned only 16 bits to the IPv4 address masks.
Additionally we assigned 32bit value 0xFFFFFFF to the TCP port numbers.
This second part does not matter as the value would be truncated to
16bits regardless, but it is unnecessary.
Fix the reported masks to properly report that the entire field is
masked.

Our hardware does not allow situations where two filters might conflict
when matching. Essentially hardware only programs one filter for each
set of matching criteria. We don't support filters with overlapping
input sets, because each flow type can only use a single input set.
Additionally, different flow types will never have overlapping matches,
because of how the hardware parses the flow type before checking
matching criteria.
For this reason, we do not need or use the location number when
programming filters to hardware.
In order to avoid confusing scenarios with filters that match the same
criteria but program the flow to different queues, do not allow multiple
filters that match identical criteria to be programmed.
This ensures that we avoid odd scenarios when deleting filters, and when
programming new filters that match the same criteria.
Instead, users that wish to update the criteria for a filter must use
the same location id, or must delete all the matching filters first.

When implementing support for IP_USER_FLOW filters, we correctly
programmed a filter for both the non fragmented IPv4/Other filter, as
well as the fragmented IPv4 filters. However, we did not properly
program the input set for fragmented IPv4 PCTYPE. This meant that the
filters would almost certainly not match, unless the user specified all
of the flow types.
Add support to program the fragmented IPv4 filter input set. Since we
always program these filters together, we'll assume that the two input
sets must match, and will thus always program the input sets to the same
value.
