57564e15d0 captured: increase ring buffer 
5000 packets translated to just about 2 hours, which is not long enough.

5a07d6696d split integration tests into multiple packages 
This makes them complete more quickly (because they are run in parallel) and
invalidates only the cache for the integration test I’m working on, not for all
of them.

3ba84074c7 dhcp4d: send replies as unicast using raw sockets 
Preferring unicast over multicast (which hogs a lot of airtime on WiFi networks)
is a best practice.

Some device/access point vendor combinations even seem to entirely eat (some?)
broadcast traffic (sometimes), e.g. my Apple iPhone SE/Ubiquiti UAP-AC-HD, so
that using unicast is required for reliable WiFi.
