staging: Switch back to struct platform_driver::remove()

After commit 0edb555a65d1 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.

Convert all staging drivers to use .remove(), with the eventual goal to
drop struct platform_driver::remove_new(). As .remove() and .remove_new()
have the same prototypes, conversion is done by just changing the structure
member name in the driver initializer.

These drivers don't use the driver_data member of struct i2c_device_id,
so don't explicitly initialize this member.

This prepares putting driver_data in an anonymous union which requires

Merge branch 'net-phy-marvell-88q2xxx-enable-auto-negotiation-for-mv88q2110'

Niklas Söderlund says:

====================
net: phy: marvell-88q2xxx: Enable auto negotiation for mv88q2110

This series enables auto negotiation for the mv88q2110 device.
Previously this feature have been disabled for mv88q2110, while enabled
for other devices supported by this driver.

The initial driver implementation states this is due to the
configuration sequence provided by the vendor did not work. By comparing
the initialization sequence of other devices this driver supports and
the out-of-tree PHY driver for mv88q2110 found in the Renesas BSP [1]
I was able to figure out a working configuration.

As I have no access to the datasheets of either of these devices it
would be super if someone who has could sanity check the initialization
sequence.

With this series I'm able to auto negotiate both 1000Mbps and 100Mbps
links without issue.

    # ethtool eth0
    Settings for eth0:
            Supported ports: [  ]
            Supported link modes:   100baseT1/Full
                                    1000baseT1/Full
            Supported pause frame use: Symmetric Receive-only
            Supports auto-negotiation: Yes
            Supported FEC modes: Not reported
            Advertised link modes:  100baseT1/Full

And the performance is good too. Without this change I was not able to
manually configure a 1000Mbps link, only 100Mbps ones. So this gives a
huge performance boost for my use-case.

net: phy: marvell-88q2xxx: Enable auto negotiation for mv88q2110

The initial marvell-88q2xxx driver only supported the Marvell 88Q2110
PHY without auto negotiation support. The reason documented states that
the provided initialization sequence did not to work. Now a method to
enable auto negotiation have been found by comparing the initialization
of other supported devices and an out-of-tree PHY driver.

Perform the minimal needed initialization of the PHY to get auto
negotiation working and remove the limitation that disables the auto
negotiation feature for the mv88q2110 device.

With this change a 1000Mbps full duplex link is able to be negotiated
between two mv88q2110 and the link works perfectly. The other side also
reflects the manually configure settings of the master device.

only a 100Mpps link so this change providers an improvement in
performance for this device.

net: phy: aquantia: allow forcing order of MDI pairs

Despite supporting Auto MDI-X, it looks like Aquantia only supports
swapping pair (1,2) with pair (3,6) like it used to be for MDI-X on
100MBit/s networks.

When all 4 pairs are in use (for 1000MBit/s or faster) the link does not
come up with pair order is not configured correctly, either using
MDI_CFG pin or using the "PMA Receive Reserved Vendor Provisioning 1"
register.

Normally, the order of MDI pairs being either ABCD or DCBA is configured
by pulling the MDI_CFG pin.

However, some hardware designs require overriding the value configured
by that bootstrap pin. The PHY allows doing that by setting a bit in
"PMA Receive Reserved Vendor Provisioning 1" register which allows
ignoring the state of the MDI_CFG pin and another bit configuring
whether the order of MDI pairs should be normal (ABCD) or reverse
(DCBA). Pair polarity is not affected and remains identical in both
settings.

Introduce property "marvell,mdi-cfg-order" which allows forcing either
normal or reverse order of the MDI pairs from DT.

If the property isn't present, the behavior is unchanged and MDI pair
order configuration is untouched (ie. either the result of MDI_CFG pin
pull-up/pull-down, or pair order override already configured by the
bootloader before Linux is started).

Forcing normal pair order is required on the Adtran SDG-8733A Wi-Fi 7

====================
selftests: mlxsw: Stabilize RED tests

Tweak the mlxsw-specific RED selftests to increase stability on
Spectrum-3 and Spectrum-4 machines.

selftests: mlxsw: sch_red_core: Lower TBF rate

The RED test uses a pair of TBF shapers. The first to get predictably-sized
stream of traffic, and second to get a 100% saturated chokepoint. To this
chokepoint it injects individual packets. Because the chokepoint is
saturated, these additional packets go straight to the backlog. This allows
the test to check RED behavior across various queue sizes.

The shapers are rated at 1Gbps, for historical reasons (before mlxsw
supported TBF offload, the test used port speed to create the chokepoints).
Machines with a low-power CPU may have trouble consistently generating
1Gbps of traffic, and the test then spuriously fails.

Instead, drop the rate to 200Mbps (Spectrum has a guaranteed shaper rate
granularity of 200Mbps, so anything lower is not guaranteed to work well).
Because that means fewer packets will be mirrored in the ECN-mark test,
adjust the passing condition accordingly.

selftests: mlxsw: sch_red_core: Send more packets for drop tests

This test works by injecting into a port with a maxed-out queue a couple
packets and checks if a corresponding number of packets were dropped. This
has worked well on Spectrum<4, but on Spectrum-4 it has been noisy. This
is in line with the observation that on Spectrum-4, queue size tends to
fluctuate more. A handful of packets could then still be accepted to the
queue even though it was nominally full just recently.

In order to accommodate this behavior, send many more packets. The buffer
can fit N extra packets, but not N% packets. This therefore allows us to
set wider absolute margins, while actually narrowing them relatively.

selftests: mlxsw: sch_red_core: Sleep before querying queue depth

The qdisc stats are taken from the port's periodic HW stats, which are
updated once a second. We try to accommodate the latency by using busywait
in build_backlog().

The issue in that seems to be that when do_mark_test() builds the backlog,
it makes the decision whether to send more packets based on the first
instance of the queue depth stat exceeding the current value, when in fact
more traffic is on the way and the queue depth would increase further. This
leads to failures in TC 1 of mark-mirror test, where we see the following
failure:

TEST: TC 0: marked packets mirror'd                                 [ OK ]
TEST: TC 1: marked packets mirror'd                                 [FAIL]
        Spurious packets (1680 -> 2290) observed without buffer pressure

Fix by waiting for the full second before reading the queue depth for the
first time, to make sure it reflects all in-flight traffic.

selftests: mlxsw: sch_red_core: Increase backlog size tolerance

Backlog fluctuates on Spectrum-4 much more than on <4. In practice we can

Merge branch 'rtnetlink-per-netns-rtnl'

Kuniyuki Iwashima says:

====================
rtnetlink: Per-netns RTNL.

rtnl_lock() is a "Big Kernel Lock" in the networking slow path and
serialised all rtnetlink requests until 4.13.

Since RTNL_FLAG_DOIT_UNLOCKED and RTNL_FLAG_DUMP_UNLOCKED have been
introduced in 4.14 and 6.9, respectively, rtnetlink message handlers
are ready to be converted to RTNL-less/free.

15 out of 44 dumpit()s have been converted to RCU so far, and the
progress is pretty good.  We can now dump various major network
resources without RTNL.

12 out of 87 doit()s have been converted, but most of the converted
doit()s are also on the reader side of RTNL; their message types are
RTM_GET*.

So, most of RTM_(NEW|DEL|SET)* operations are still serialised by RTNL.

For example, one of our services creates 2K netns and a small number
of network interfaces in each netns that require too many writer-side
rtnetlink requests, and setting up a single host takes 10+ minutes.

RTNL is still a huge pain for network configuration paths, and we need
more granular locking, given converting all doit()s would be unfeasible.

Actually, most RTNL users do not need to freeze multiple netns, and such
users can be protected by per-netns RTNL mutex.  The exceptions would be
RTM_NEWLINK, RTM_DELLINK, and RTM_SETLINK.  (See [0] and [1])

This series is the first step of the per-netns RTNL conversion that
gradually replaces rtnl_lock() with rtnl_net_lock(net) under
CONFIG_DEBUG_NET_SMALL_RTNL.

Once an RTNL scope is converted with rtnl_net_lock(), we will replace
RTNL helper functions inside the scope with the following per-netns
alternatives:

  ASSERT_RTNL()           -> ASSERT_RTNL_NET(net)
  rcu_dereference_rtnl(p) -> rcu_dereference_rtnl_net(net, p)

Note that the per-netns helpers are equivalent to the conventional
helpers unless CONFIG_DEBUG_NET_SMALL_RTNL is enabled.
