Description David Juran 2006-12-04 19:12:57 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.0.8) Gecko/20061105 Red Hat/1.5.0.8-0.1.el4 Firefox/1.5.0.8 pango-text

Description of problem:
I have a NIC using the tg3 driver. When I boot the machine with the Xen kernel ethtool will only report link status when ran in Dom0. 

[root@hat ~]# uname -a
Linux hat.netact.noklab.net 2.6.18-1.2849.fc6xen #1 SMP Fri Nov 10 12:57:36 EST 2006 x86_64 x86_64 x86_64 GNU/Linux
[root@hat ~]# ethtool eth0
Settings for eth0:
        Link detected: yes

Rebooting with the "standard" kernel gives me all the other settings as well.

(This is a mass-update to all current FC6 kernel bugs in NEW state)

Hello,

I'm reviewing this bug list as part of the kernel bug triage project, an attempt
to isolate current bugs in the Fedora kernel.

http://fedoraproject.org/wiki/KernelBugTriage

I am CC'ing myself to this bug, however this version of Fedora is no longer
maintained.

Please attempt to reproduce this bug with a current version of Fedora (presently
Fedora 8). If the bug no longer exists, please close the bug or I'll do so in a
few days if there is no further information lodged.

Thanks for using Fedora!

Closing as NOTABUG. I got confused by eth0 no longer being the physical
interface in DOM0. So the correct thing to do is to run "ethtool peth0" which
works fine. If anyone is interested, Bug 209996 is about NetworkManager testing
the wrong interface in DOM0
