PSFP rules take effect on the streams from any port of VSC9959 switch.
This patch use ingress port to limit the rule only active on this port.
Each stream can only match two ingress source ports in VSC9959. Streams
from lowest port gets the configuration of SFID pointed by MAC Table
lookup and streams from highest port gets the configuration of (SFID+1)
pointed by MAC Table lookup. This patch defines the PSFP rule on highest
port as dummy rule, which means that it does not modify the MAC table.

This patch add police action to set flow meter table which is defined
in IEEE802.1Qci. Flow metering is two rates two buckets and three color
marker to policing the frames, we only enable one rate one bucket in
this patch.
Flow metering shares a same policer pool with VCAP policers, so the PSFP
policer calls ocelot_vcap_policer_add() and ocelot_vcap_policer_del() to
set flow meter police.

Policer was previously automatically assigned from the highest index to
the lowest index from policer pool. But police action of tc flower now
uses index to set an police entry. This patch uses the police index to
set vcap policers, so that one policer can be shared by multiple rules.

VSC9959 supports Per-Stream Filtering and Policing(PSFP) that complies
with the IEEE 802.1Qci standard. The stream is identified by Null stream
identification(DMAC and VLAN ID) defined in IEEE802.1CB.
For PSFP, four tables need to be set up: stream table, stream filter
table, stream gate table, and flow meter table. Identify the stream by
parsing the tc flower keys and add it to the stream table. The stream
filter table is automatically maintained, and its index is determined by
SGID(flow gate index) and FMID(flow meter index).

Some chips in the ocelot series such as VSC9959 support Per-Stream

ocelot_mact_learn_streamdata() can be used in VSC9959 to overwrite an
FDB entry with stream data. The stream data includes SFID and SSID which
can be used for PSFP and FRER set.
ocelot_mact_lookup() can be used to check if the given {DMAC, VID} FDB
entry is exist, and also can retrieve the DEST_IDX and entry type for

In 99ce45d5e, we moved a route refcount decrement from
mctp_do_fragment_route into the caller. This invalidates the assumption
that the route test makes about refcount behaviour, so the route tests
fail.
This change fixes the test case to suit the new refcount behaviour.

10GbE Intel Wired LAN Driver Updates 2021-11-17
Radoslaw Tyl says:
The change is a consequence of errors reported by the ixgbevf driver
while starting several virtual guests at the same time on ESX host.
During this, VF was not able to communicate correctly with the PF,
as a result reported "PF still in reset state. Is the PF interface up?"
and then goes to locked state. The only thing left was to reload
the VF driver on the guest OS.
The background of the problem is that the current PFU and VFU
semaphore locking mechanism between sender and receiver may cause
overriding Mailbox memory (VFMBMEM), in such scenario receiver of
the original message will read the invalid, corrupted or one (or more)
message may be lost.
This change is actually as a support for communication with PF ESX
driver and does not contains changes and support for ixgbe driver.
For maintain backward compatibility, previous communication method
has been preserved in the form of LEGACY functions.
In the future there is a plan to add a support for a 1.5 mailbox API
communication also to ixgbe driver.

Improve reliability of the mailbox communication and remove
its potential flaws that may lead to the undefined or faulty behavior.
Recently some users reported issues on ESX with 10G Intel NICs which were
found to be caused by incorrect implementation of the PF-VF mailbox
communication.
Technical investigation highlighted areas to improve in the communication
between PF or VF that wants to send the message (sender) and the other
part which receives the message (receiver):
- Locking the mailbox when the sender wants to send a message
- Releasing the mailbox when the communication ends
- Returning the result of the mailbox message execution

net: make dev_watchdog() less intrusive
dev_watchdog() is used on many NIC to periodically monitor TX queues
to detect hangs.
Problem is : It stops all queues, then check them, then 'unfreeze' them.
Not only this stops feeding the NIC, it also migrates all qdiscs
to be serviced on the cpu calling netif_tx_unlock(), causing
a potential latency artifact.
With many TX queues, this is becoming more visible.
