Tom sorry about sending this reply twice, struggle here is with 
Thunderbird mail UI sometimes hiding "Reply All" and it missed the mail 
list first time around.

'1' literal does not seem to do something so I guess it is meant the id 
of the first ethernet interface:

 From power-on:

...

starfive_7110_pcie pcie at 2c000000: Starfive PCIe bus probed.

Again, from power-on:
