====================
MCTP I2C driver

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

I think I've addressed all the points raised in v5. It now has
mctp_i2c_unregister() to run things in the correct order, waiting for
the worker thread and I2C rx to complete.

Cheers,
Matt
