EBAZ4205 Bitcoin miner board - Network

I hook up a cable and on the console we see: 
zedboard-zynq7 login: macb e000b000.ethernet eth0: unable to generate target frequency: 25000000 Hz
macb e000b000.ethernet eth0: link up (100/Full)
IPv6: ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready

With the bitcoin miner startup in place

The startup chatter indicated it is running an http server first on 192.168.80.140, then on 192.168.36.66

Of course my home machine is on 192.168.0.x, so I do the following: 

su
ip addr add 192.168.36.5/24 brd + dev eno1 label eno1:bc1
ip addr add 192.168.80.5/24 brd + dev eno1 label eno1:bc2

I can ping the second address, but not the first. And aiming a browser at the second gets redirected to use https and then brings up a user login dialog -- with a radio button choice of CH or EN as a language. The main point in all of this is that the network is fully functional!

Without the bitcoin miner startup in place

The network is not set up!
I add the following lines to /etc/xx/interfaces Then type ifup eth0, and I am on the air. I reboot, and I am still on the air, so I can get rid of the extra routes on my desktop linux and this board is now part of my regular network setup with a static IP.
Feedback? Questions? Drop me a line!
