Provides MCTP network transport over an I3C bus, as specified in DMTF DSP0233. Each I3C bus (with "mctp-controller" devicetree property) gets an "mctpi3cX" net device created. I3C devices are reachable as remote endpoints through that net device. Link layer addressing uses the I3C PID as a fixed hardware address for neighbour table entries. The driver matches I3C devices that have the MIPI assigned DCR 0xCC for MCTP.

This driver provides an MCTP-over-serial interface, through a
|
|
serial line-discipline, as defined by DMTF specification "DSP0253 -
|
|
MCTP Serial Transport Binding". By attaching the ldisc to a serial
|
|
device, we get a new net device to transport MCTP packets.
|
|
|
|
This allows communication with external MCTP endpoints which use
|
|
serial as their transport. It can also be used as an easy way to
|
|
provide MCTP connectivity between virtual machines, by forwarding
|
|
data between simple virtual serial devices.
|
|
|
|
Say y here if you need to connect to MCTP endpoints over serial. To
|
|
compile as a module, use m; the module will be called mctp-serial.
