Not that it helps much, unless you manage to push it down in the WiFi
network card properly.

Uh? Why? Changing the MAC address to the DECnet address is essentially
required for DECnet to work. Meaning not changing it will make starting
DECnet hard...

DECnet over wireless probably isn't going to be achievable since many WiFi environments are particularly IP centric and don't pass arbitrary other packets, and even if they did, you would have to convince the host NIC to use a DECnet MAC address for everything. There probably isn't a way to set the host network device's MAC address so that won't get you there.
