Hi Ben,

I was stumbling with this the other day as well.  One thing to make sure 
is that the pc3000r type is set to use the correct control interface. 
This will control which interface is listed as control in the new node 
setup page.

The Linux/BSD ordering is a separate issue from which interface is 
considered to be the control interface.  What I did is reorder the 
interfaces as they appear under Linux, then made sure the type for those 
nodes used the control interface index as listed in the Linux order.

For example, our nodes have two buitin NICs  (em0, em1), and three PCI 
cards (sk0..2).  Under BSD they are ordered with the em interfaces 
first, but under Linux the sk interfaces come first.  We use em0 as the 
control, so what I did was first reorder the interface numbers in the 
new node setup:

FreeBSD Linux
0       3
1       4
2       0
3       1
4       2

Then, I made sure that the type for these nodes (pc3400 in our case) 
used interface 3 as the control interface.  Once this was done, the web 
interface displayed the correct MAC address for the control interface.
