From: Petr Machata <petrm@xxxxxxxxxxxx>
If there are any offloaded FDB entries at an NVE device at the time that
it's un-offloaded, their offloaded marks need to be cleared. How that is
done depends on NVE device type, and therefore add a per-NVE-type
operation.
Implement the operation for the sole NVE device type currently supported
by mlxsw, VXLAN.
