mctp: Add MCTP-over-serial transport binding This change adds a MCTP Serial transport binding, as defined by DMTF specificiation DSP0253 - "MCTP Serial Transport Binding". This is implemented as a new serial line discipline, and can be attached to arbitrary tty devices. From the Kconfig description: 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. Once the N_MCTP line discipline is set [using ioctl(TCIOSETD)], we get a new netdev suitable for MCTP communication. The 'mctp' utility[1] provides a simple wrapper for this ioctl, using 'link serial <device>': # mctp link serial /dev/ttyS0 & # mctp link dev lo index 1 address 0x00:00:00:00:00:00 net 1 mtu 65536 up dev mctpserial0 index 5 address 0x(no-addr) net 1 mtu 68 down [1]: https://github.com/CodeConstruct/mctp Signed-off-by: Jeremy Kerr <jk@codeconstruct.com.au> Signed-off-by: David S.
