Subject: [PATCH net 0/7] bridge: Fix corner case problems around local fdb entries

There are so many corner cases that are not handled properly around local
fdb entries.
- We might fail to delete the old entry and might delete an arbitrary local
  entry when changing mac address of a bridge port.
- We always fail to delete the old entry when changing mac address of the
  bridge device.
- We might incorrectly delete a necessary entry when detaching a bridge port.
- We might incorrectly delete a necessary entry when deleting a vlan.
and so on.

This is a patch series to fix these issues.

Toshiaki Makita (7):
  bridge: Fix the way finding the old local fdb entry in
    br_fdb_changeaddr
  bridge: Fix the way finding the old local fdb entry in
    br_fdb_change_mac_address
  bridge: Change local fdb entries whenever mac address of bridge device
    changes
  bridge: Fix the way checking if a local fdb entry can be deleted
  bridge: Properly check if local fdb entry can be deleted in
    br_fdb_change_mac_address
  bridge: Properly check if local fdb entry can be deleted in
    br_fdb_delete_by_port

    vlan
