====================
mlxsw: Preparations for VxLAN support

This patchset prepares mlxsw for VxLAN support. It contains small and
mostly non-functional changes.

The first eight patches perform small changes in the code to make it
more receptive towards the actual VxLAN changes in the next patchset.

Patches 9-17 add the registers used to configure the device for VxLAN
offload.

Last two patches add the required resources and trap IDs.

The next patchset is available here [1].
