I had hoped (not very hopefully) the solution wouldn't involve bashing 
kernel parameters.

 From previous journeys in this area systemd-networkd does a much neater 
job and has huge numbers of options.

This is my worstation config

root@client:/etc/systemd/network# cat wired_lan.network

[Match]
Name=enp7s0

[Network]

DHCP=yes

Address=10.31.40.68/24
Gateway=10.31.40.1
DNS=10.31.40.4 10.31.40.5

Address=2403:5800:c101:b700:beef::44/64
IPv6PrivacyExtensions=yes
IPv6AcceptRA=yes

Domains=lan example.com

[IPv6AcceptRA]
