7 title: MCTP I2C transport binding
13 An mctp-i2c-controller defines a local MCTP endpoint on an I2C controller.
14 MCTP I2C is specified by DMTF DSP0237.
16 An mctp-i2c-controller must be attached to an I2C adapter which supports
18 busses) are attached to the mctp-i2c-controller with a 'mctp-controller'
19 property on each used bus. Each mctp-controller I2C bus will be presented
20 to the host system as a separate MCTP I2C instance.

11 This driver provides an MCTP-over-serial interface, through a
13 MCTP Serial Transport Binding". By attaching the ldisc to a serial
14 device, we get a new net device to transport MCTP packets.
16 This allows communication with external MCTP endpoints which use

21 Say y here if you need to connect to MCTP endpoints over serial. To
22 compile as a module, use m; the module will be called mctp-serial.

Dmctp.rst4 Management Component Transport Protocol (MCTP)
7 net/mctp/ contains protocol support for MCTP, as defined by DMTF standard
9 provided in drivers/net/mctp/.
11 The core code provides a socket-based interface to send and receive MCTP
17 The kernel models the local MCTP topology through two items: interfaces and
20 An interface (or "link") is an instance of an MCTP physical transport binding
24 A network defines a unique address space for MCTP endpoints by endpoint-ID
41 MCTP uses ``AF_MCTP`` / ``PF_MCTP`` for the address- and protocol- families.
42 Since MCTP is message-based, only ``SOCK_DGRAM`` sockets are supported.
