Hi,

This patch series adds a netdev driver providing MCTP transport over
I2C. 

Since the v3 submission I have switched to using I2C transfers
which support >32 bytes. It could be switch back to smbus transfers
once 255 byte support is ready. It now doesn't require any changes to
I2C core.

The dt-bindings patch went through review on the list.

Cheers,
Matt
