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

v6:
- Changed netdev register/unregister/free to avoid races. Ensure that
netif functions are not used by irq handler/threads after unregister.
- Fix incoming I2C hwaddr that was previously incorrect (left
shifted 1 bit)
- Add a check that byte_count wire header matches the length received
- Renamed I2C driver to mctp-i2c-interface
- Removed __func__ from print messages, added missing newlines
- Removed sysfs mctp_current_mux file which was used for debug
- Renamed curr_lock to sel_lock
- Tidied comment formatting
- Fix newline in Kconfig
v5:
- Fix incorrect format string
v4:
- Switch to __i2c_transfer() rather than __i2c_smbus_xfer(), drop 255 byte
smbus patches
- Use wait_event_idle() for the sleeping TX thread
- Use dev_addr_set()
v3:
- Added Reviewed-bys for npcm7xx
- Resend with net-next open
v2:
- Simpler Kconfig condition for i2c-mux dependency, from Randy Dunlap
