(In reply to Lucas Aubard from comment #15)

Using multiple VMs on a lab, then having to reduce the amount of available RAM
to a level not commonly found in today's real hardware is indeed a common
pitfall that many have encountered before.

However, I have reviewed what is currently available on the market:
- Raspberry Pi current version (5) come with 2GB RAM;
- The smallest AWS EC2 instances have 4GB RAM;
- But on Google and Microsoft Azure we can have 1GB RAM instance;


Thus, this reassembly issue is expected behavior in low-RAM scenarios, but how
critical is it? (This is a question for Lucas.)

I mean, is it worth adding a warning message if net.inet.ip.maxfragbucketsize
is configured to 1, or do we need to find a more complex solution?"
