====================
mlxsw: Preparations for VRF offload

Ido says:

This patchset aims to prepare the mlxsw driver for VRF offload. The
follow-up patchsets that introduce VRF support can be found here:
https://github.com/idosch/linux/tree/idosch-next

The first four patches are mainly concerned with the netdevice
notification block. There are no functional changes, but merely
restructuring to more easily integrate VRF enslavement.

Patches 5-10 remove various assumptions throughout the code about a
single virtual router (VR) and also restructure the internal data
structures to more accurately represent the device's operation.
====================
