I feel rather stupid, but it turns out to be a misconfigurated switch
sitting between the dhcp server and the network the laptop. I was looking
for traffic on the dhcpd's subnetwork with wireshark and saw nothing. It

works as expected.
BTW: with Alpine Linux 3.23.3 as guest I can't get networking working.
OpenBSD works fine.
Since I upgraded a Arch Linux VM to the latest release with kernel 6.18
I see the same thing. I can see ethernet packets with ARP requests on
the tap interface, but the source MAC is set to all zeros. The VM can't
talk. Alpine 3.23 was also released with a 6.18 kernel.
