Add a driver with initial support for the Arrow SpeedChips XRS7000
series of gigabit Ethernet switch chips which are typically used in
critical networking applications.
The switches have up to three RGMII ports and one RMII port.
Management to the switches can be performed over i2c or mdio.
Support for advanced features such as PTP and
HSR/PRP (IEC 62439-3 Clause 5 & 4) is not included in this patch and
may be added at a later date.

Add further DT configuration for AT803x PHYs
This patch series adds the ability to configure the SmartEEE feature
in AT803x PHYs. SmartEEE defaults to enabled on these PHYs, and has
a history of causing random sporadic link drops at Gigabit speeds.
There appears to be two solutions to this. There is the approach that
Freescale adopted early on, which is to disable the SmartEEE feature.
However, this loses the power saving provided by EEE. Another solution
was found by Jon Nettleton is to increase the Tw parameter for Gigabit
links.
This patch series adds support for both approaches, by adding a boolean:
qca,disable-smarteee
if one wishes to disable SmartEEE, and two properties to configure the
SmartEEE Tw parameters:
qca,smarteee-tw-us-100m
qca,smarteee-tw-us-1g
Sadly, the PHY quirk I merged a while back for AT8035 on iMX6 is broken
- rather than disabling SmartEEE mode, it enables it.
The addition of these properties will be sent to the appropriate
platform maintainers - although for SolidRun platforms, we only make use
of "qca,smarteee-tw-us-1g".

SmartEEE for the atheros phy was deemed buggy by Freescale and commits
were added to disable it for their boards.
In initial testing, SolidRun found that the default settings were
causing disconnects but by increasing the Tw buffer time we could allow
enough time for all parts of the link to come out of a low power state
and function properly without causing a disconnect. This allows us to
have functional power savings of between 300 and 400mW, rather than
disabling the feature altogether.
This commit adds support for disabling SmartEEE and configuring the Tw
parameters for 1G and 100M speeds.

net: dsa: Link aggregation support
Start of by adding an extra notification when adding a port to a bond,
this allows static LAGs to be offloaded using the bonding driver.
Then add the generic support required to offload link aggregates to
drivers built on top of the DSA subsystem.
Finally, implement offloading for the mv88e6xxx driver, i.e. Marvell's
LinkStreet family.
Supported LAG implementations:
- Bonding
- Team
Supported modes:
- Isolated. The LAG may be used as a regular interface outside of any
bridge.
- Bridged. The LAG may be added to a bridge, in which case switching
is offloaded between the LAG and any other switch ports. I.e. the
LAG behaves just like a port from this perspective.
In bridged mode, the following is supported:
- STP filtering.
- VLAN filtering.
- Multicast filtering. The bridge correctly snoops IGMP and configures
the proper groups if snooping is enabled. Static groups can also be
configured. MLD seems to work, but has not been extensively tested.
- Unicast filtering. Automatic learning works. Static entries are
_not_ supported. This will be added in a later series as it requires
some more general refactoring in mv88e6xxx before I can test it.
v4 -> v5:
- Cleanup PVT configuration for LAGed ports in mv88e6xxx (Vladimir)
- Document dsa_lag_{map,unmap} (Vladimir)

Packets ingressing on a LAG that egress on the CPU port, which are not
classified as management, will have a FORWARD tag that does not
contain the normal source device/port tuple. Instead the trunk bit
will be set, and the port field holds the LAG id.
Since the exact source port information is not available in the tag,
frames are injected directly on the LAG interface and thus do never
pass through any DSA port interface on ingress.
Management frames (TO_CPU) are not affected and will pass through the
DSA port interface as usual.

Monitor the following events and notify the driver when:
- A DSA port joins/leaves a LAG.
- A LAG, made up of DSA ports, joins/leaves a bridge.
- A DSA port in a LAG is enabled/disabled (enabled meaning
"distributing" in 802.3ad LACP terms).
When a LAG joins a bridge, the DSA subsystem will treat that as each
individual port joining the bridge. The driver may look at the port's
LAG device pointer to see if it is associated with any LAG, if that is
required. This is analogue to how switchdev events are replicated out
to all lower devices when reaching e.g. a LAG.
Drivers can optionally request that DSA maintain a linear mapping from
a LAG ID to the corresponding netdev by setting ds->num_lag_ids to the
desired size.
In the event that the hardware is not capable of offloading a
particular LAG for any reason (the typical case being use of exotic
modes like broadcast), DSA will take a hands-off approach, allowing
the LAG to be formed as a pure software construct. This is reported
back through the extended ACK, but is otherwise transparent to the
user.

In a situation where a standalone port is indirectly attached to a
bridge (e.g. via a LAG) which is not offloaded, do not offload any
port attributes either. The port should behave as a standard NIC.
Previously, on mv88e6xxx, this meant that in the following setup:
br0
/
team0
/ \
swp0 swp1
If vlan filtering was enabled on br0, swp0's and swp1's QMode was set
to "secure". This caused all untagged packets to be dropped, as their

When creating a static bond (e.g. balance-xor), all ports will always
be enabled. This is set, and the corresponding notification is sent
out, before the port is linked to the bond upper.
In the offloaded case, this ordering is hard to deal with.
The lower will first see a notification that it can not associate with
any bond. Then the bond is joined. After that point no more
notifications are sent, so all ports remain disabled.
This change simply sends an extra notification once the port has been
linked to the upper to synchronize the initial state.

"One single fix to skip BPF selftests by default.
BPF selftests have a hard dependency on cutting edge versions of tools
in the BPF ecosystem including LLVM.
Skipping BPF allows by default will make it easier for users
interested in running kselftest as a whole. Users can include BPF in
Kselftest build by via SKIP_TARGETS variable"

Pull networking fixes from Jakub Kicinski:
"We have a few fixes for long standing issues, in particular Eric's fix
to not underestimate the skb sizes, and my fix for brokenness of
register_netdevice() error path. They may uncover other bugs so we
will keep an eye on them. Also included are Willem's fixes for
kmap(_atomic).
Looking at the "current release" fixes, it seems we are about one rc
behind a normal cycle. We've previously seen an uptick of "people had
run their test suites" / "humans actually tried to use new features"
fixes between rc2 and rc3.
Summary:
Current release - regressions:

tcp_disconnect() expects the caller acquires the sock lock,
but mptcp_disconnect() is not doing that. Add the missing
required lock.

Cited patch below blocked the TLS TX device offload unless HW_CSUM
is set. This broke devices that use IP_CSUM && IP6_CSUM.
Here we fix it.
Note that the single HW_TLS_TX feature flag indicates support for
both IPv4/6, hence it should still be disabled in case only one of
(IP_CSUM | IPV6_CSUM) is set.
Fixes: ae0b04b238 ("net: Disable NETIF_F_HW_TLS_TX when HW_CSUM is disabled")
