There were several cases where validate() would return bogus supported
modes with unusual combinations of interfaces and capabilities. For
example, if state->interface was 10GBASER and the macb had HIGH_SPEED
and PCS but not GIGABIT MODE, then 10/100 modes would be set anyway. In
another case, SGMII could be enabled even if the mac was not a GEM
(despite this being checked for later on in mac_config()). These
inconsistencies make it difficult to refactor this function cleanly.
There is still the open question of what exactly the requirements for
SGMII and 10GBASER are, and what SGMII actually supports. If someone
from Cadence (or anyone else with access to the GEM/MACB datasheet)
could comment on this, it would be greatly appreciated. In particular,
what is supported by Cadence vs. vendor extension/limitation?
To address this, the current logic is split into three parts. First, we
determine what we support, then we eliminate unsupported interfaces, and
finally we set the appropriate link modes. There is still some cruft
related to NA, but this can be removed in a future patch.

====================
introduce generic phylink validation
The various validate method implementations we have in phylink users
have been quite repetitive but also prone to bugs. These patches
introduce a generic implementation which relies solely on the
supported_interfaces bitmap introduced during last cycle, and in the
first patch, a bit array of MAC capabilities.
MAC drivers are free to continue to do their own thing if they have
special requirements - such as mvneta and mvpp2 which do not support
1000base-X without AN enabled. Most implementations currently in the
kernel can be converted to call phylink_generic_validate() directly
from the phylink MAC operations structure once they fill in the
supported_interfaces and mac_capabilities members of phylink_config.
This series introduces the generic implementation, and converts mvneta
and mvpp2 to use it.

MCTP I2C driver
This patch series adds a netdev driver providing MCTP transport over
I2C.
It applies against net-next using recent MCTP changes there, though also
has I2C core changes for review. I'll leave it to maintainers where it
should be applied - please let me know if it needs to be submitted
differently.
The I2C patches were previously sent as RFC though the only feedback
there was an ack to 255 bytes for aspeed.

====================
Signed-off-by: David S. Miller <davem@davemloft.net>
Provides MCTP network transport over an I2C bus, as specified in
DMTF DSP0237. All messages between nodes are sent as SMBus Block Writes.
Each I2C bus to be used for MCTP is flagged in devicetree by a
'mctp-controller' property on the bus node. Each flagged bus gets a
mctpi2cX net device created based on the bus number. A
'mctp-i2c-controller' I2C client needs to be added under the adapter. In
an I2C mux situation the mctp-i2c-controller node must be attached only
to the root I2C bus. The I2C client will handle incoming I2C slave block
write data for subordinate busses as well as its own bus.
In configurations without devicetree a driver instance can be attached
to a bus using the I2C slave new_device mechanism.
The MCTP core will hold/release the MCTP I2C device while responses
are pending (a 6 second timeout or once a socket is closed, response
received etc). While held the MCTP I2C driver will lock the I2C bus so
that the correct I2C mux remains selected while responses are received.
(Ideally we would just lock the mux to keep the current bus selected for
the response rather than a full I2C bus lock, but that isn't exposed in
the I2C mux API)
This driver requires I2C adapters that allow 255 byte transfers
(SMBus 3.0) as the specification requires a minimum MTU of 68 bytes.

Used to define a local endpoint to communicate with MCTP peripherals
attached to an I2C bus. This I2C endpoint can communicate with remote
MCTP devices on the I2C bus.
In the example I2C topology below (matching the second yaml example) we
have MCTP devices on busses i2c1 and i2c6. MCTP-supporting busses are
indicated by the 'mctp-controller' DT property on an I2C bus node.
A mctp-i2c-controller I2C client DT node is placed at the top of the
mux topology, since only the root I2C adapter will support I2C slave
functionality.

SMBus 3.0 increased the maximum block transfer size from 32 bytes to

i2c_smbus_xfer() and i2c_smbus_xfer_emulated() now support 255 byte
block operations, other block functions remain limited to 32 bytes for
compatibility with existing callers.
We allow adapters to indicate support for the larger size with
I2C_FUNC_SMBUS_V3_BLOCK. Most emulated drivers should be able to use 255
