Well to answer my own question, I was able to add a rule to /etc/udev/rules.d/70-persistent-net.rules to name the device:
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="f4:52:14:43:50:01", NAME="p6p2"
Of course this was the first thing I tried but managed to enter the MAC incorrectly (missed the leading 'f' when I cut and pasted). All good now. -- Bud
