PORT_PHY_CONFIG is always sent with REQ_FLAGS_RESET_PHY set. This flag
must be set in order for the firmware to institute the requested PHY
change immediately, but it results in a link flap. This is unnecessary
and results in an improved user experience if the PHY reconfiguration
is avoided when the user requested speed does not constitute a change.

On some 200G dual port NICs, if one port is configured to 200G,
firmware will disable the ethernet link on the other port. Firmware
will send notification to the driver for the disabled port when this
happens. Define a new field in the link_info structure to keep track
of this state. The new phy_state field replaces the unused loop_back
field.
Log a message when the phy_state changes state. In the disabled state,
disallow any PHY configurations on the disabled port as the firmware
will fail all calls to configure the PHY in this state.

It will be necessary to update more than one field in the link_info
structure when PAM4 speeds are added in a later patch. Instead of
merely translating ethtool speed values to firmware speed values,
change the responsiblity of this function to update all the necessary
link_info fields required to force the speed change to the desired
ethtool value. This also reduces code duplication somewhat at the two
call sites, which otherwise both have to independently update link_info
fields to turn off auto negotiation advertisements.
Also use the appropriate REQ_FORCE_LINK_SPEED definitions. These happen
to have the same values, but req_link_speed is utilimately passed as
force_link_speed in HWRM_PORT_PHY_CFG which is not defined in terms of
REQ_AUTO_LINK_SPEED.

Extract the code for determining an advertised speed is no longer

The main changes include FEC, ECN statistics, HWRM_PORT_PHY_QCFG
response size reduction, and a new counter added to
ctx_hw_stats_ext struct to support the new 58818 chip.
The ctx_hw_stats_ext structure is now the superset supporting the new
58818 chips and the prior P5 chips. Add a new flag to identify the new
chip and use constants for the chip specific ring statistics sizes
instead of the size of the structure.
Because the HWRM_PORT_PHY_QCFG response structure size has shrunk back
to 96 bytes, the workaround added earlier to limit the size of this
message for forwarding to the VF can be removed.

There are 2 goals that we follow:
- Reduce the header size
- Make the header size equal between RX and TX
The issue that required long prefix on RX was the fact that the ocelot
DSA tag, being put before Ethernet as it is, would overlap with the area
that a DSA master uses for RX filtering (destination MAC address
mainly).
Now that we can ask DSA to put the master in promiscuous mode, in theory
we could remove the prefix altogether and call it a day, but it looks
like we can't. Using no prefix on ingress, some packets (such as ICMP)
would be received, while others (such as PTP) would not be received.
This is because the DSA master we use (enetc) triggers parse errors
("MAC rx frame errors") presumably because it sees Ethernet frames with
a bad length. And indeed, when using no prefix, the EtherType (bytes
12-13 of the frame, bits 96-111) falls over the REW_VAL field from the
extraction header, aka the PTP timestamp.
When turning the short (32-bit) prefix on, the EtherType overlaps with
bits 64-79 of the extraction header, which are a reserved area
transmitted as zero by the switch. The packets are not dropped by the
DSA master with a short prefix. Actually, the frames look like this in
tcpdump (below is a PTP frame, with an extra dsa_8021q tag - dadb 0482 -
added by a downstream sja1105).
89:0c:a9:f2:01:00 > 88:80:00:0a:00:1d, 802.3, length 0: LLC, \
dsap Unknown (0x10) Individual, ssap ProWay NM (0x0e) Response, \
ctrl 0x0004: Information, send seq 2, rcv seq 0, \
Flags [Response], length 78
0x0000: 8880 000a 001d 890c a9f2 0100 0000 100f ................
0x0010: 0400 0000 0180 c200 000e 001f 7b63 0248 ............{c.H
0x0020: dadb 0482 88f7 1202 0036 0000 0000 0000 .........6......
0x0030: 0000 0000 0000 0000 0000 001f 7bff fe63 ............{..c
0x0040: 0248 0001 1f81 0500 0000 0000 0000 0000 .H..............
0x0050: 0000 0000 0000 0000 0000 0000 ............
So the short prefix is our new default: we've shortened our RX frames by
12 octets, increased TX by 4, and headers are now equal between RX and
TX. Note that we still need promiscuous mode for the DSA master to not
drop it.

Remove the ocelot_configure_cpu() function, which was in fact bringing
up 2 ports: the CPU port module, which both switchdev and DSA have, and
the NPI port, which only DSA has.
The (non-Ethernet) CPU port module is at a fixed index in the analyzer,
whereas the NPI port is selected through the "ethernet" property in the
device tree.
Therefore, the function to set up an NPI port is DSA-specific, so we
move it there, simplifying the ocelot switch library a little bit.

This reverts commit 546c044c9651e81a16833806feff6b369bb5de33.
Nothing prevents user from sending frames to "external" VxLAN devices.
In fact kernel itself may generate icmp chatter.
This is fine, such frames should be dropped.
The point of the "missing encapsulation" warning was that
frames with missing encap should not make it into vxlan_xmit_one().
And vxlan_xmit() drops them cleanly, so let it just do that.
Without this revert the warning is triggered by the udp_tunnel_nic.sh
test, but the minimal repro is:
$ ip link add vxlan0 type vxlan \
group 239.1.1.1 \

The devlink core recently gained support for checking whether the driver
supports a flash_update parameter, via `supported_flash_update_params`.
However, parameters are specified as function arguments. Adding a new
parameter still requires modifying the signature of the .flash_update
callback in all drivers.
Convert the .flash_update function to take a new `struct
devlink_flash_update_params` instead. By using this structure, and the
`supported_flash_update_params` bit field, a new parameter to
flash_update can be added without requiring modification to existing
drivers.
As before, all parameters except file_name will require driver opt-in.
Because file_name is a necessary field to for the flash_update to make
sense, no "SUPPORTED" bitflag is provided and it is always considered
valid. All future additional parameters will require a new bit in the
supported_flash_update_params bitfield.

When implementing .flash_update, drivers which do not support
per-component update are manually checking the component parameter to
verify that it is NULL. Without this check, the driver might accept an
update request with a component specified even though it will not honor
such a request.
Instead of having each driver check this, move the logic into
net/core/devlink.c, and use a new `supported_flash_update_params` field
in the devlink_ops. Drivers which will support per-component update must
now specify this by setting DEVLINK_SUPPORT_FLASH_UPDATE_COMPONENT in
the supported_flash_update_params in their devlink_ops.
This helps ensure that drivers do not forget to check for a NULL
component if they do not support per-component update. This also enables
a slightly better error message by enabling the core stack to set the
netlink bad attribute message to indicate precisely the unsupported
attribute in the message.
Going forward, any new additional parameter to flash update will require
a bit in the supported_flash_update_params bitfield.

When adding the support for TBF offload, the improper command version
was added even though the command format is for the V2 of
dpni_set_tx_shaping(). This does not affect the functionality of TBF
since the only change between these two versions is the addition of the
exceeded parameters which are not used in TBF. Still, fix the bug so
that we keep things in sync.

Some devices set needed_headroom. If we ignore it, we might
end up crashing in various skb_push() for example in ipgre_header()
since some layers assume enough headroom has been reserved.

syzbot managed to crash a host by creating a bond
with a GRE device.
For non Ethernet device, bonding calls bond_setup_by_slave()
instead of ether_setup(), and unfortunately dev->needed_headroom
was not copied from the new added member.

Since commit aab8cc3630e32
("vxlan: add support for underlay in non-default VRF")
vxlan_find_sock() also checks if socket is assigned to the right
level 3 master device when lower device is not in the default VRF.
