Instead of disabling TSO at compile time if MAX_SKB_FRAGS > 32,
implement ndo_features_check() method for this driver for
a more dynamic handling.
If skb has more than 32 frags and is a GSO packet, force
software segmentation.
Most locally generated packets will use a small number
of fragments anyway.
For forwarding workloads, we can limit gro_max_size at ingress,
we might also implement gro_max_segs if needed.

It seems this one-element array is not actually being used as an
array of variable size, so we can just replace it with just a
non-array object of type struct desc_frag and refactor a bit the
rest of the code.
This helps with the ongoing efforts to globally enable -Warray-bounds
and get us closer to being able to tighten the FORTIFY_SOURCE routines
on memcpy().
This issue was found with the help of Coccinelle and audited and fixed,
manually.

There is a regular need in the kernel to provide a way to declare having
a dynamically sized set of trailing elements in a structure. Kernel code
should always use “flexible array members”[1] for these cases. The older
style of one-element or zero-length arrays should no longer be used[2].

Rather than tracking the number of receive buffer transactions that
have been submitted without a doorbell, just track the total number
of transactions that have been issued. Then ring the doorbell when
that number modulo the replenish batch size is 0.
The effect is roughly the same, but the new count is slightly more
interesting, and this approach will someday allow the replenish
batch size to be tuned at runtime.

When replenishing, have ipa_endpoint_replenish() allocate a
transaction, and pass that to ipa_endpoint_replenish_one() to fill.
Then, if that produces no error, commit the transaction within the
replenish loop as well. In this way we can distinguish between
transaction failures and buffer allocation/mapping failures.
Failure to allocate a transaction simply means the hardware already
has as many receive buffers as it can hold. In that case we can
break out of the replenish loop because there's nothing more to do.
If we fail to allocate or map pages for the receive buffer, just
try again later.

A transaction failure only occurs if no more transactions are
available for an endpoint. It's a very cheap test.
When replenishing an RX endpoint buffer, there's no point in

The replenish_saved field keeps track of the number of times a new
buffer is added to the backlog when replenishing is disabled. We
don't really use it though, so there's no need for us to track it
separately. Whether replenishing is enabled or not, we can simply
increment the backlog.

In some cases, the IPA hardware needs to request the always-on
subsystem (AOSS) to coordinate with the IPA microcontroller to
retain IPA register values at power collapse. This is done by
issuing a QMP request to the AOSS microcontroller. A similar
request ondoes that request.
We must get and hold the "QMP" handle early, because we might get
back EPROBE_DEFER for that. But the actual request should be sent
while we know the IPA clock is active, and when we know the
microcontroller is operational.

The decision whether to report serdes statistics currently depends on
the cached C_Mode value for the port, read at probe time or updated by
configuration. However, port 4 can be in "automedia" mode when it is
used as a serdes port, meaning it switches between the internal PHY and
the serdes, changing the read-only C_Mode value depending on which
first gains link. Consequently, the C_Mode value read at probe does not
accurately reflect whether the port has the serdes associated with it.
In "net: dsa: mv88e6xxx: add mv88e6352_g2_scratch_port_has_serdes()",
we added a way to read the hardware configuration to determine which
port has the serdes associated with it. Use this to determine which

Given that standalone ports are now configured to bypass the ATU and
forward all frames towards the upstream port, extend the ATU bypass to
multichip systems.
Load VID 0 (standalone) into the VTU with the policy bit set. Since
VID 4095 (bridged) is already loaded, we now know that all VIDs in use
are always available in all VTUs. Therefore, we can safely enable
802.1Q on DSA ports.
Setting the DSA ports' VTU policy to TRAP means that all incoming
frames on VID 0 will be classified as MGMT - as a result, the ATU is
bypassed on all subsequent switches.
With this isolation in place, we are able to support configurations
that are simultaneously very quirky and very useful. Quirky because it
involves looping cables between local switchports like in this
example:
CPU
| .------.
.---0---. | .----0----.
| sw0 | | | sw1 |
'-1-2-3-' | '-1-2-3-4-'
$ @ '---' $ @ % %
We have three physically looped pairs ($, @, and %).
This is very useful because it allows us to run the kernel's
kselftests for the bridge on mv88e6xxx hardware.

Clear MapDA on standalone ports to bypass any ATU lookup that might
point the packet in the wrong direction. This means that all packets
are flooded using the PVT config. So make sure that standalone ports
are only allowed to communicate with the local upstream port.
Here is a scenario in which this is needed:
CPU
| .----.
.---0---. | .--0--.
| sw0 | | | sw1 |
'-1-2-3-' | '-1-2-'
'---'
- sw0p1 and sw1p1 are bridged
- sw0p2 and sw1p2 are in standalone mode
- Learning must be enabled on sw0p3 in order for hardware forwarding
to work properly between bridged ports
1. A packet with SA :aa comes in on sw1p2
1a. Egresses sw1p0
1b. Ingresses sw0p3, ATU adds an entry for :aa towards port 3
1c. Egresses sw0p0
2. A packet with DA :aa comes in on sw0p2
2a. If an ATU lookup is done at this point, the packet will be
incorrectly forwarded towards sw0p3. With this change in place,
the ATU is bypassed and the packet is forwarded in accordance
with the PVT, which only contains the CPU port.

This commit also results in the Autoneg bit being set in the ethtool
link modes, which wasn't in the original; if this switch supports

Populate the supported interfaces and MAC capabilities for the bcm_sf2
DSA switch and remove the old validate implementation to allow DSA to
use phylink_generic_validate() for this switch driver.
The exclusion of Gigabit linkmodes for MII and Reverse MII links is
handled within phylink_generic_validate() in phylink, so there is no
need to make them conditional on the interface mode in the driver.
Thanks to Florian Fainelli for suggesting how to populate the supported
interfaces.
