Some of use cases:

- Standard MCTP message handling
- MCTP bridging 
- Support SMBUS ( PCIe in future) 
- MCTP tool( from console) that can be used to send any MCTP messages to a device and read responses, discovery etc.

Can you explain what are problems with libmctp(SMBUS binding ) with current implementation?

What features are you looking for? Keen to see discussion about people's MCTP needs.

Anyway, OpenBMC's MCTP support is in progress but fairly immature.
Part of the plan is to move MCTP support into the kernel. If you're making use of MCTP then I'd like to hear your use-cases so I can make sure the kernel interface meets everyone's requirements.

IBM is using libmctp in both BMC and host firmware, and Intel is working on it for use in their BMCs (but not host firmware).
