Since commit 3b4477d2dcf2709d0be89e2a8dced3d0f4a017f2 ("VSOCK: use TCP
state constants for sk_state") VSOCK has used TCP_* constants for
sk_state.
Commit b4562ca7925a3bedada87a3dd072dd5bad043288 ("hv_sock: add locking
in the open/close/release code paths") reintroduced the SS_DISCONNECTING
constant.
This patch replaces the old SS_DISCONNECTING with the new TCP_CLOSING
constant.

net: sched: sch_api: fix coding style issues for extack
this patch prepares to handle extack for qdiscs and fixes checkpatch
issues.
There are a bunch of warnings issued by checkpatch which bothered me.
This first patchset is to get rid of those warnings to make way for
the next patchsets.
I plan to followup with qdiscs, classifiers and actions after this.

This patch fixes the following checkpatch error:
ERROR: do not use assignment in if condition
by rearranging the if condition to execute init callback only if init
callback exists. The whole setup afterwards is called in any case,
doesn't matter if init callback is set or not. This patch has the same
behaviour as before, just without assign err variable in if condition.
It also makes the code easier to read.

nfp: enhanced debug dump via ethtool
Add debug dump implementation to the NFP driver. This makes use of
existing ethtool infrastructure. ethtool -W is used to select the dump
level and ethtool -w is used to dump NFP state.
The existing behaviour of dump level 0, dumping the arm.diag resource, is
preserved. Dump levels greater than 0 are implemented by this patchset and
optionally supported by firmware providing a _abi_dump_spec rtsym. This
rtsym provides a specification, in TLV format, of the information to be
dumped from the NFP at each supported dump level.
Dumps are also structured using a TLVs. They consist a prolog and the data
described int he corresponding dump.

- The spec defines CSR address ranges for indirect ME CSRs. For Each TLV
chunk in the spec, dump a chunk that includes the spec and the data
over the defined address range.
- Each indirect CSR has 8 contexts. To read one context, first write the
context to a specific derived address, read it back, and then read the
register value.
- For each address, read and dump all 8 contexts in this manner.

Both Eric and Paolo noticed the rcu_barrier() we use in
tcf_block_put_ext() could be a performance bottleneck when
we have a lot of tc classes.
Paolo provided the following to demonstrate the issue:
tc qdisc add dev lo root htb
for I in `seq 1 1000`; do
tc class add dev lo parent 1: classid 1:$I htb rate 100kbit
tc qdisc add dev lo parent 1:$I handle $((I + 1)): htb
for J in `seq 1 10`; do
tc filter add dev lo parent $((I + 1)): u32 match ip src 1.1.1.$J
done
done
time tc qdisc del dev root
real 0m54.764s
user 0m0.023s
sys 0m0.000s
The rcu_barrier() there is to ensure we free the block after all chains
are gone, that is, to queue tcf_block_put_final() at the tail of workqueue.
We can achieve this ordering requirement by refcnt'ing tcf block instead,
that is, the tcf block is freed only when the last chain in this block is
gone. This also simplifies the code.
Paolo reported after this patch we get:
real 0m0.017s
user 0m0.000s
sys 0m0.017s

net: sh_eth: DMA mapping API fixes
Here are two patches that fix how the sh_eth driver is using the DMA

struct device is used.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
Using NULL as argument for the DMA mapping API is bogus, as the DMA
mapping API may use information from the "struct device" to perform
the DMA mapping operation. Therefore, pass the appropriate "struct
device".

There are two types of "struct device": the one representing the
physical device on its physical bus (platform, SPI, PCI, etc.), and
the one representing the logical device in its device class (net,
etc.).
The DMA mapping API expects to receive as argument a "struct device"
representing the physical device, as the "struct device" contains
information about the bus that the DMA API needs.
However, the sh_eth driver mistakenly uses the "struct device"
representing the logical device (embedded in "struct net_device")
rather than the "struct device" representing the physical device on
its bus.
This commit fixes that by adjusting all calls to the DMA mapping API.

Teach phylib hard-resetting devices
This patch series adds optional PHY reset support to phylib.
The first two patches are destined for David's net-next tree. They add
core PHY reset code, and update a driver that currently uses its own
reset code.
The last two patches are destined for Simon's renesas tree. They add
properties to describe the EthernetAVB PHY reset topology to the common
Salvator-X/XS and ULCB DTS files, which solves two issues:
1. On Salvator-XS, the enable pin of the regulator providing PHY power
is connected to PRESETn, and PSCI powers down the SoC during system
suspend. Hence a PHY reset is needed to restore network
functionality after system resume.
2. Linux should not rely on the boot loader having reset the PHY, but
should reset the PHY during driver probe.
Changes compared to v3:
- Remove Florian's Acked-by,
- Add missing #include <linux/gpio/consumer.h>,
- Re-add the gpiod check, as the dummy gpiod_set_value() for !GPIOLIB
does not ignore NULL, and calls WARN_ON(1),
- Do not reassert the reset signal if {mdio,phy}_probe() or
phy_device_register() succeeded, as that may destroy initial setup,
- Do not deassert the reset signal in {mdio,phy}_remove(), as it
should already be deasserted,
- Bring the PHY back into reset state in phy_device_remove(),
- Move/consolidate GPIO descriptor acquiring code from
of_mdiobus_register_phy() and of_mdiobus_register_device() to
mdiobus_register_device().
Note that this changes behavior slightly, in that the reset signal
is now also asserted when called from of_mdiobus_register_device().
- Add Reviewed-by,
Changes compared to v2, as sent by Sergei Shtylyov:
- Fix fwnode_get_named_gpiod() call due to added parameters (which
allowed to eliminate the gpiod_direction_output() call),
- Rebased, refreshed, reworded,
- Take over from Sergei,
- Add Acked-by,
- Remove unneeded gpiod check, as gpiod_set_value() handles NULL fine,
- Handle fwnode_get_named_gpiod() errors correctly:
- -ENOENT is ignored (the GPIO is optional), and turned into NULL,
which allowed to remove all later !IS_ERR() checks,
- Other errors (incl. -EPROBE_DEFER) are propagated,
- Extract DTS patches from series "[PATCH 0/4] ravb: Add PHY reset
support" (https://www.spinics.net/lists/netdev/msg457308.html), and
incorporate in this series, after moving reset-gpios from the
ethernet to the ethernet-phy node.
Given (1) the new reset-gpios DT property in the PHY node follows
established practises, (2) the DT binding change in the first patch has
been acked by Rob, and (3) the DTS patch does not cause any regressions
if it is applied before the PHY driver patches, the DTS patches can be
applied independently.

there should be no need to frob the PHY reset in this driver anymore...

The PHY devices sometimes do have their reset signal (maybe even power
supply?) tied to some GPIO and sometimes it also does happen that a boot
loader does not leave it deasserted. So far this issue has been attacked
from (as I believe) a wrong angle: by teaching the MAC driver to manipulate
the GPIO in question; that solution, when applied to the device trees, led
to adding the PHY reset GPIO properties to the MAC device node, with one
exception: Cadence MACB driver which could handle the "reset-gpios" prop
in a PHY device subnode. I believe that the correct approach is to teach
the 'phylib' to get the MDIO device reset GPIO from the device tree node
corresponding to this device -- which this patch is doing...
Note that I had to modify the AT803x PHY driver as it would stop working
otherwise -- it made use of the reset GPIO for its own purposes...

Move dissection of tunnel info to outside of the main flow dissection
function, __skb_flow_dissect(). The sole user of this feature, the flower
classifier, is updated to call tunnel info dissection directly, using
skb_flow_dissect_tunnel_info().
This results in a slightly less complex implementation of
__skb_flow_dissect(), in particular removing logic from that call path
which is not used by the majority of users. The expense of this is borne by
the flower classifier which now has to make an extra call for tunnel info
dissection.
This patch should not result in any behavioural change.

According to LS1021A RM, the value of PAL can be set so that the start of the
IP header in the receive data buffer is aligned to a 32-bit boundary. Normally,
setting PAL = 2 provides minimal padding to ensure such alignment of the IP
header.
However every incoming packet's 8-byte time stamp will be inserted into the
packet data buffer as padding alignment bytes when hardware time stamping is
enabled.
So we set the padding 8+2 here to avoid the flooded alignment faults:

net: hns3: Refactors "reset" handling code in HCLGE layer of HNS3 driver
This patch refactors the code of the reset feature in HCLGE layer
of HNS3 PF driver. Prime motivation to do this change is:
1. To reduce the time for which common miscellaneous Vector 0
interrupt is disabled because of the reset. Simplification
of the common miscellaneous interrupt handler routine(for
Vector 0) used to handle reset and other sources of Vector
0 interrupt.
2. Separate the task for handling the reset
3. Simplification of reset request submission and pending reset
logic.
To achieve above below few things have been done:
1. Interrupt is disabled while common miscellaneous interrupt
handler is entered and re-enabled before it is exit. This
reduces the interrupt handling latency as compared to older
interrupt handling scheme where interrupt was being disabled
in interrupt handler context and re-enabled in task context
some time later. Made Miscellaneous interrupt handler more
generic to handle all sources including reset interrupt source.
2. New reset service task has been introduced to service the
reset handling.
3. Introduces new reset service task for honoring software reset
requests like from network stack related to timeout and serving
the pending reset request(to reset the driver and associated
clients).

In exisiting code, the way to detect if driver/client reset should
be executed or if hardware should be be soft resetted was overly
complex.
Existing code use to read the interrupt status register from task
context to figure out if the interrupt source event was reset and
then use clear the interrupt source for reset while waiting for the
hardware to finish the reset. This behaviour again was confusing
and overly complex in terms of the flow.
This patch simplifies the handling of the requested reset and the
pending reset(i.e. reset which have already been asserted by the
software and hardware has acknowledged back to driver that it is
processing the hardware reset through interrupt)

Existing common service task was being used to service the reset

by separating task to handle the reset requests. This might in
turn help in adapting similar handling approach for other
interrupt events like mailbox, sharing vector 0 interrupt.

The reset interrupt event shares common miscellaneous interrupt
Vector 0. In the existing reset interrupt handling we disable
the Vector 0 interrupt in misc interrupt handler and re-enable
them later in context to common service task.
This also means other event sources like mailbox would also be
deferred or if the interrupt event was due to mailbox(which shall
be supported for VF soon), it could delay the reset handling.
This patch reorganizes the reset interrupt handling logic and
makes it more fair to other events.
