- Around line 66-83: Update the get_entries test to patch mikrotik.normalize_mac
with distinct sentinel return values, assert it is called for each eligible
lease MAC, and verify plugin_objects.add_object uses those sentinels as
primaryId values instead of raw MAC addresses.
- Around line 13-18: Update the stub helper and its cleanup logic to preserve
any pre-existing sys.modules entry before overwriting it, then restore that
entry in a finally block; only remove module names that had no prior entry.
Ensure this applies to all modules stubbed during test collection, including the
setup around the helper’s uses.

- Around line 71-73: Update the _lease fixture for 192.168.1.5 in the Mikrotik
scan regression test to use status="bound" while retaining its missing MAC
address, so get_entries exercises the bound MAC-less lease branch. Add a
separate disabled-lease fixture only if needed to preserve coverage for that
status.

Fixes #1228.
Problem
A DHCP lease without a
mac-addressmade the MikroTik scanner call.lower()onNonebefore checking the lease status. Because the exception handler wraps the whole lease loop, one disabled or waiting lease stopped the scan and prevented later bound devices from being reported.Fix
Treat the lease MAC as optional, and only normalize and add leases that are both bound and have a MAC address. A regression test covers waiting and bound MAC-less leases between valid bound leases.
User impact
MikroTik scans continue past leases without MAC addresses, so later bound devices are still discovered.
