When a bridge is created for a physical interface eth0 then physical
interface eth0 become a virtaul interface for dom0 and peth0 becomes
the real physical interface .
So there is nothing wrong here.
Try #ethtool peth0 to get the real physical information of interface eth0.
Thanks,

I have the xensource 3.1.0 x86_64 tarball installed over
a RHEL5 clone distribution. The "ethtool" utility only
returns the following information:
[root@fermigrid5 etc]# ethtool eth0
Settings for eth0:
Link detected: yes
[root@fermigrid5 etc]#
Since I have no vanilla-installed rhel5 machines with which to compare,
I am not sure if I am dealing with a bug in the ethtool
(whose output should look like this, or if I am dealing with
some wierdness in the xenized kernel that doesn't support
the extra network function calls, or if I am dealing with a mismatch
between the ethtool and the xen kernel.
Any ideas?
It should look like this:
[root@fermigrid4 var]# ethtool eth0
