Add fwnode APIs for finding and getting I2C adapters, which will be
used by the SFP code. These are passed the fwnode corresponding to
the adapter, and return the I2C adapter. It is the responsibility of
the caller to find the appropriate fwnode.
We keep the DT and ACPI interfaces, but where appropriate, recode them
to use the fwnode interfaces internally.

This supports that individual rules are enabled and disabled via chain
information.
This is done by keeping disabled rules in the VCAP list (cached) until they
are enabled, and only at this time are the rules written to the VCAP HW.

This allows a VCAP rule to be in one of 3 states:
- permanently stored in the VCAP HW (for rules that must always be present)
- enabled (stored in HW) when the corresponding lookup has been enabled
- disabled (stored in SW) when the lookup is disabled
This way important VCAP rules can be added even before the user enables the
VCAP lookups using a TC matchall filter.

This changes the way the chain information verified when adding a new tc
flower filter.
When adding a flower filter it is now checked that the filter contains a
goto action to one of the IS2 VCAP lookups, except for the last lookup
which may omit this goto action.
It is also checked if you attempt to add multiple matchall filters to
enable the same VCAP lookup. This will be rejected.

This adds both the source and destination chain id to the information kept
for enabled port lookups.
This allows enabling and disabling a chain of lookups by walking the chain
information for a port.
This changes the way that VCAP lookups are enabled from userspace: instead
of one matchall rule that enables all the 4 Sparx5 IS2 lookups, you need a
matchall rule per lookup.
In practice that is done by adding one matchall rule in chain 0 to goto IS2
Lookup 0, and then for each lookup you add a rule per lookup (low priority)
that does a goto to the next lookup chain.
Examples:
If you want IS2 Lookup 0 to be enabled you add the same matchall filter as
before:
tc filter add dev eth12 ingress chain 0 prio 1000 handle 1000 matchall \
skip_sw action goto chain 8000000
If you also want to enable lookup 1 to 3 in IS2 and chain them you need
to add the following matchall filters:
tc filter add dev eth12 ingress chain 8000000 prio 1000 handle 1000 \
matchall skip_sw action goto chain 8100000
tc filter add dev eth12 ingress chain 8100000 prio 1000 handle 1000 \
matchall skip_sw action goto chain 8200000
tc filter add dev eth12 ingress chain 8200000 prio 1000 handle 1000 \
matchall skip_sw action goto chain 8300000

The conversion to the platform specific multi-word format is moved from the

This changes the VCAP lookups state to always be enabled so that it is
possible to add "internal" VCAP rules that must be available even though
the user has not yet enabled the VCAP chains via a TC matchall filter.

The switch receives management traffic such as STP and LLDP. However, PTP
messages are not received, only transmitted.
Ideally, the switch would trap all PTP messages to the management CPU. This
particular switch has a PTP block which identifies PTP messages and traps them
to a dedicated port. There is a register to program this destination. This is
not used at the moment.
Therefore, program it to the same port as the MGMT traffic is trapped to. This
allows to receive PTP messages as soon as timestamping is enabled.
In addition, the datasheet mentions that this register is not valid e.g., for
6190 variants. So, add a new PTP operation which is added for the 6390 and 6290
devices.
Tested simply like this on Marvell 88E6390, revision 1:

Build multi-buffer xdp using virtnet_build_xdp_buff_mrg().
For the prefilled buffer before xdp is set, we will probably use
vq reset in the future. At the same time, virtio net currently
uses comp pages, and bpf_xdp_frags_increase_tail() needs to calculate
the tailroom of the last frag, which will involve the offset of the
corresponding page and cause a negative value, so we disable tail
increase by not setting xdp_rxq->frag_size.

When single-buffer xdp is loaded, the size of the buffer filled each time
is 'sz = (PAGE_SIZE - headroom - tailroom)', which is the maximum packet
length that the driver allows the device to pass in. Otherwise, the packet
with a length greater than sz will come in, so num_buf will be greater than
or equal to 2, and xdp_linearize_page() will be performed and the packet
will be dropped because the total length is greater than PAGE_SIZE. So the
maximum value of MTU for single-buffer xdp is 'max_sz = sz - ETH_HLEN'.

dcb ets set dev $dev tc-tsa 0:ets 1:ets 2:ets 3:ets 4:ets 5:ets \
6:ets 7:ets tc-bw 0:0 1:80 2:0 3:0 4:0 5:0 6:20 7:0
dcb maxrate set dev $dev tc-maxrate 1:1000bit
And DCB configuration can be shown using:
dcb ets show dev $dev
dcb maxrate show dev $dev
