net: dsa: use per-port upstream port
An upstream port is a local switch port used to reach a CPU port.
DSA still considers a unique CPU port in the whole switch fabric and
thus return a unique upstream port for a given switch. This is wrong in
a multiple CPU ports environment.
We are now switching to using the dedicated CPU port assigned to each
port in order to get rid of the deprecated unique tree CPU port.
This patchset makes the dsa_upstream_port() helper take a port argument
and goes one step closer complete support for multiple CPU ports.

The current dsa_upstream_port() helper still assumes a unique CPU port
in the whole switch fabric. This is becoming wrong, as every port in the
fabric has its dedicated CPU port, thus every port has an upstream port.
Add a port argument to the dsa_upstream_port() helper and fetch its CPU
port instead of the deprecated unique fabric CPU port. A CPU or unused
port has no dedicated CPU port, so return itself in this case.
At the same time, change the return value from u8 to unsigned int since
there is no need to limit the size here.

The mv88e6xxx driver currently assumes a single CPU port in the fabric
and thus floods frames with unknown DA on a single DSA port, the one
that is one hop closer to the CPU port.
With multiple CPU ports in mind, this isn't true anymore because CPU
ports could be found behind both DSA ports of a device in-between
others.
For example in a A <-> B <-> C fabric, both A and C having CPU ports,
device B will have to flood such frame to its two DSA ports.
This patch considers both CPU and DSA ports of a device as upstream
ports, where to flood frames with unknown DA addresses.

optionally supported by firmware providing a _abi_dump_spec rtsym. This
rtsym provides a specification, in TLV format, of the information to be

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:

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.

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

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.

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)

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

SFP/phylink updates
This series, which follows on from the fixes posted earlier, improves
the phylink/sfp support. Changes included here are:
- Merge 802.3z and SGMII modes into one "in-band" mode, using the
PHY_INTERFACE_MODE_xxx definition to determine which should be used.
This allows more flexibility as more interface modes become
available.
- Allow 2500base-X and 10GBASE-KR to be requested from SFP.
- Remove unused and unnecessary phylink_init_eee()
- Restart 802.3z autonegotiation when starting the network device to
ensure that the negotiated parameters are always correct. It has
been observed on mvneta that this is not always the case without
this change.
- Add kerneldoc documentation for phylink and sfp upstream facing APIs
and link it in to the networking documentation.
- Resolve a sparse warning in sfp-bus.c
- Convert phylink/sfp to use fwnode rather than DT so that other firmware
systems can take advantage of this - I have received a request for it
to be usable with ACPI. The exception to this is our interactions with
phylib, as phylib itself does not yet support fwnode.

The chip family of TILEPro and TILE-Gx was developed by Tilera, which
was eventually acquired by Mellanox. The tile architecture was added to
the kernel in 2010 and first appeared in 2.6.36.
Now at Mellanox we are developing new chips based on the ARM64
architecture; our last TILE-Gx chip (the Gx72) was released in 2013, and
our customers using tile architecture products are not, as far as we
know, looking to upgrade to newer kernel releases. In the absence of
someone in the community stepping up to take over maintainership, this
commit marks the architecture as orphaned.
