Public bug reported:
netplan for infiniband does not send out any DHCP requests. It works
fine for other Ethernet interfaces. if I manually just issue 'dhclient
ibs2' is gets a DHCP address just fine.
Somehow, networkd doesn't invoke a DHCP client for infiniband networks.

It will just stay in the degraded/configuring mode forever. iptables

But if I do dhclient ibs2 it becomes...

So. My DHCP server works fine. manually calling a dhclient on the
infiniband IPoIB interface works just fine. But netplan/networkd doesn't
properly invoke DHCP clients to configure the interface.
