Prior to this patch, the "unknown" address was being set the logical
switch ports solely based on whether the port security was enabled or
disabled. That's not how it's intended to work.
With this patch the "unknown" address is only set to the normal logical
switch ports, those which types are "router", "localnet" or "localport"
won't be affected.
The maintenance task was updated to correct this behavior for existing
ports (the maintenance was suppose to be removed in the T cycle, this
patch bumps it to U cycle instead due to this change).
