====================
Fix changing DSA conduit

This series fixes an issue in the DSA code related to host interface UC
address installed into port FDB and port conduit address database when
live-changing port conduit.

The first patch refactores/deduplicates the installation/uninstallation
of the interface's MAC address and the second patch fixes the issue.

Cover letter for v1 and v2:
