Due to a reversed dependency, it is possible to build
the lower ptp driver as a loadable module and the actual
driver using it as built-in, causing a link error:

Change the Makefile logic to always build the ptp module
the same way as the rest. Another option would be to
just add it to the same module and remove the exports,
but I don't know if there was a good reason to keep them
separate.

Vhost_net was known to suffer from HOL[1] issues which is not easy to
fix. Several downstream disable the feature by default. What's more,
the datapath was split and datacopy path got the support of batching
and XDP support recently which makes it faster than zerocopy part for
small packets transmission.
It looks to me that disable zerocopy by default is more
appropriate. It cold be enabled by default again in the future if we
fix the above issues.

While data pass suspend, reuse of rx descriptors can be disabled using
channel state & lock from cpdma layer. For this, submit to a channel
has to be disabled using state != "not active" under lock, what is done
with this patch. The same submit is used to fill rx channel while
ndo_open, when channel is idled, so add idled submit routine that
allows to prepare descs for the channel. All this simplifies code and
helps to avoid dormant mode usage and send packets only to active
channels, avoiding potential race in later on changes. Also add missed
sync barrier analogically like in other places after stopping tx
queues.

This is a successor to my previous series "stmmac: honor the GPIO flags

patches from that series plus some additional cleanups on top.
I broke out the actual GPIO flag handling into a separate patch which

stmmac_mdio_reset" from [1]
I have build and runtime tested this on my ARM Meson8b Odroid-C1.

No platform uses the "reset_gpio" field from stmmac_mdio_bus_data
anymore. Drop it so we don't get any new consumers either.
Plain GPIO numbers are being deprecated in favor of GPIO descriptors. If
needed any new non-OF platform can add a GPIO descriptor lookup table.
devm_gpiod_get_optional() will find the GPIO in that case.

Change stmmac_mdio_reset() to use device_property_read_u32_array()
instead of of_property_read_u32_array().
This is meant as a cleanup because we can drop the struct device_node
variable. Also it will make it easier to get rid of struct
stmmac_mdio_bus_data (or at least make it private) in the future because
non-OF platforms can now pass the reset delays as device properties.
No functional changes (neither for OF platforms nor for ones that are
not using OF, because the modified code is still contained in an "if
(priv->device->of_node)").

struct device_node *np = priv->device->of_node;
if (!np)

40GbE Intel Wired LAN Driver Updates 2019-06-14
This series contains updates to i40e only.
Aleksandr adds stub functions for Energy Efficient Ethernet (EEE) to
currently report that it is not supported in i40e. Fixed up the Link
Layer Detection Protocol (LLDP) code to ensure we do not set the LLDP
flag too early before we ensure that we have a successful start. This
also will prevent needles restarting of the device if LLDP did not
change its state with an unsuccessful start.
Piotr bumps up the amount of VLANs that an untrusted VF can implement,
from 8 VLANs to 16. Adds checks to the Virtual Embedded Bridge (VEB)
and channel arrays so access does not exceed the boundary and ensure the
index is below the maximum. Fixed an issue in the driver where we were
not checking the response from the LLDP flag and were returned success
no matter what the value of the response was.
Mitch fixes a variable counter, which can be negative in value so make
it an integer instead of an unsigned-integer.
Doug improves the admin queue log granularity by making it possible to
log only the admin queue descriptors without the entire admin queue
message buffers.
Sergey fixes up the virtchnl code by removing duplicate checks, ensure
the variable type is correct when comparing integers, enhance error and
warning messages to include useful information.
Adam fixes a potential kernel panic when the i40e driver was being bound
to a non-i40e port by adding a check on the BAR size to ensure it is
large enough by reading the highest register.
Jake fixes a statistics error in the "transmit errors" stat, which was
being calculated twice.
Gustavo A. R. Silva adds a fall-through code comment to help with
compiler checks.
v2: Fixed the return values wrapped in parenthesis in patch 8 and
cleaned up the commit message in patch 12 so the Gustavo does
not repeat himself.

Mlx5 devlink health fw reporters and sw reset support
This series provides mlx5 firmware reset support and firmware devlink health
reporters.
1) Add initial mlx5 kernel documentation and include devlink health reporters
2) Add CR-Space access and FW Crdump snapshot support via devlink region_snapshot
3) Issue software reset upon FW asserts
4) Add fw and fw_fatal devlink heath reporters to follow fw errors indication by
dump and recover procedures and enable trigger these functionality by user.
4.1) fw reporter:
The fw reporter implements diagnose and dump callbacks.
It follows symptoms of fw error such as fw syndrome by triggering
fw core dump and storing it and any other fw trace into the dump buffer.
The fw reporter diagnose command can be triggered any time by the user to check
current fw status.
4.2) fw_fatal repoter:
The fw_fatal reporter implements dump and recover callbacks.
It follows fatal errors indications by CR-space dump and recover flow.
The CR-space dump uses vsc interface which is valid even if the FW command
interface is not functional, which is the case in most FW fatal errors. The
CR-space dump is stored as a memory region snapshot to ease read by address.
The recover function runs recover flow which reloads the driver and triggers fw
reset if needed.

NAPI tx mode improves TCP behavior by enabling TCP small queues (TSQ).
TSQ reduces queuing ("bufferbloat") and burstiness.
Previous measurements have shown significant improvement for
TCP_STREAM style workloads. Such as those in commit 86a5df1495cc
("Merge branch 'virtio-net-tx-napi'").
There has been uncertainty about smaller possible regressions in
latency due to increased reliance on tx interrupts.
The above results did not show that, nor did I observe this when
rerunning TCP_RR on Linux 5.1 this week on a pair of guests in the
same rack. This may be subject to other settings, notably interrupt
coalescing.
In the unlikely case of regression, we have landed a credible runtime
solution. Ethtool can configure it with -C tx-frames [0|1] as of
commit 0c465be183c7 ("virtio_net: ethtool tx napi configuration").
NAPI tx mode has been the default in Google Container-Optimized OS
(COS) for over half a year, as of release M70 in October 2018,
without any negative reports.

Presently the HNS driver enables the HNS H/W error interrupts after
the dev initialization is completed. However some exceptions such as
NCSI errors can occur when the network port driver is not loaded
and those errors required reporting to the BMC.
Therefore the firmware enabled all the HNS ras error interrupts
before the driver is loaded. And in some cases, there will be some
H/W errors remained unclear before reboot. Thus the HNS driver needs
to process and recover those hw errors occurred before HNS driver is
initialized.
This patch adds processing of the HNS hw errors(RAS and MSI-X)
which occurred before the driver initialization. For RAS, because
they are enabled by firmware, so we can detect specific bits, then
log and clear them. But for MSI-X which can not be enabled before
open vector0 irq, we can't detect the specific error bits, so we
just write 1 to all interrupt source registers to clear.

Presently the error handling code sets the reset level required
for the recovery of the hw errors to the reset framework in the
error_detected AER callback. However the rest_event would be
called later from the slot_reset callback. This can cause issue
of using the wrong reset_level if a high priority reset request
occur before the slot_reset is called.
This patch delays setting of the reset level, required

Destroy QP waits for it's ep object state to be set to CLOSED
before proceeding. ep->state can be updated from a different
context. Add smp_store_release/READ_ONCE to synchronize.

The acpi_node_get_property_reference() doesn't return ACPI error codes,
it just returns regular negative kernel error codes. This patch doesn't
affect run time, it's just a clean up.

Apparently there are still cards in the wild with a very old
management FW. Let's make the error message in that case
indicate more clearly that management firmware has to be
updated.

The KSZ9477 series chips have a SYNCLKO pin which by default outputs a
25MHz clock, but some board setups require a 125MHz clock instead. Added
a microchip,synclko-125 device tree property to allow indicating a
125MHz clock output is required.

The Silicon Errata and Data Sheet Clarification documents for the
KSZ9477 series of chips describe a number of otherwise undocumented PHY
register settings which are required to work around various chip errata.
Apply these settings when initializing the PHY ports on these chips.

Switch stmmac_mdio_reset to use GPIO descriptors. GPIO core handles the
"snps,reset-gpio" for GPIO descriptors so we don't need to take care of
it inside the driver anymore.
The advantage of this is that we now preserve the GPIO flags which are
passed via devicetree. This is required on some newer Amlogic boards
which use an Open Drain pin for the reset GPIO. This pin can only output
a LOW signal or switch to input mode but it cannot output a HIGH signal.
There are already devicetree bindings for these special cases and GPIO
core already takes care of them but only if we use GPIO descriptors
instead of GPIO numbers.

Commit "net: phy: Add detection of 1000BaseX link mode support" added
support for not filtering out 1000BaseX mode from the PHY's supported
modes in genphy_config_init, but we have to make a similar change in
genphy_read_abilities in order to actually detect it as a supported mode
in the first place. Add this in.
