Fingerbank: unknown DHCP fingerprint when receiving one DHCP request #5546
Description
Describe the bug
When you receive only one DHCP request for a node, Fingerbank is not able to get complete profiling for node. You need to do a manual refresh of profiling.
To Reproduce
Steps to reproduce the behavior:
- Configure a Fingerbank API key
- Send one DHCP request for a node
- Check device profiling on Fingerbank tab
=> You don't get a complete profiling.
- Refresh Fingerbank or send a new DHCP request
=> You get complete profiling.
Expected behavior
Fingerbank should be able to get correct profile with only one DHCP request.
