net: ethernet: ti: davinci_cpdma: use idled submit
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.

stmmac: cleanups for stmmac_mdio_reset
This is a successor to my previous series "stmmac: honor the GPIO flags
for the PHY reset GPIO" from [0]. It contains only the "cleanup"
patches from that series plus some additional cleanups on top.
I broke out the actual GPIO flag handling into a separate patch which
is already part of net-next: "net: stmmac: use GPIO descriptors in
stmmac_mdio_reset" from [1]
I have build and runtime tested this on my ARM Meson8b Odroid-C1.
net: stmmac: drop the reset delays from struct stmmac_mdio_bus_data
Only OF platforms use the reset delays and these delays are only read in
stmmac_mdio_reset(). Move them from struct stmmac_mdio_bus_data to a
stack variable inside stmmac_mdio_reset() because that's the only usage
of these delays.

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.

Change stmmac_mdio_reset() to use device_property_read_u32_array()

This is meant as a cleanup because we can drop the struct device_node

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.

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.

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

Previous measurements have shown significant improvement for

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

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.
