What I meant in this thread with external timer events I now wrote down
-- https://hannes.nqsb.io/Posts/ARP  https://github.com/hannesm/arp

Unfortunately not easy to drop in as a replacement since mirage - the
tool - has pretty much hardcoded tcpip.arpv4 and Arpv4 as a module name.

Upside: found a bug in mirage-tcpip
(https://github.com/mirage/mirage-tcpip/issues/225 via Martin's
unikernel-runner)

Downside: V1.ARP does not have the right semantics... how useful is an
ARP handler which has no IPv4 address?
