This patchset adds VxLAN learning support in the mlxsw driver. The first five patches from Petr add the required switchdev APIs which allow device drivers to notify the VxLAN driver about learned / aged-out FDB entries. First in patch #1, an unnecessary argument is dropped from __vxlan_fdb_delete(). In patches #2-#4, the VxLAN FDB handling code is extended to make sending the switchdev events configurable; to mark user-added entries as such; and to make sure HW-learned FDB entries do not take over user-added ones. Finally in patch #5, the necessary switchdev notifications are added and handled by VxLAN, similarly to how this is handled in the bridge driver. Patch #6 allows changing of the VxLAN's device ageing time since it is useful for the selftest in the last patch. Patch #7 adds support for querying bridge port flags of a given netdevice, as a new entry should not be learned and notified to the bridge driver in case learning is disabled on the bridge port. Next patches gradually add learning support in mlxsw. The last patch adds a new test case for VxLAN learning.
