Hi again,

Just tried the "racadm ifconfig" command for the first time. Something
is plain wrong on all of these DRACs :

$ racadm ifconfig
bond0     Link encap:Ethernet  HWaddr 00:1D:09:70:79:7B
          inet addr:192.168.169.103  Bcast:192.168.169.255

          RX packets:20 errors:0 dropped:0 overruns:0 frame:0
          TX packets:20 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0
          RX bytes:1692 (1.6 KiB)  TX bytes:1692 (1.6 KiB)

$ racadm getconfig -g cfgLanNetworking -o cfgNicEnable
1
$

Why the heck are these DRACs bonding two eth interfaces with the same
MAC address as one bonded interfaces with the same MAC address?
Everywhere this happens, it's always eth1 and eth2 as bond0. On DRACs
where things work, I just have eth0 and lo as expected.

This looks like a weird corner case or simply a bug :-)
