Red Hat Bugzilla – Bug 621378
RTL8111/8168B does not appear to negotiate 100Mbps/Full Duplex, but actually does.
Last modified: 2011-06-28 10:58:28 EDT
I've just installed F13/x64 on a brand new Athlon II x2 240 based system.
Motherboard: GigaByte GA-880GM-UD2H (not GA-EP45-DS5 as lspci reports below).
During the install, from the F13/x64 Live-USB, I was unable to get a DHCP lease using this card. I has to use a USB network card in order to even complete the install (for some reason anaconda would crash if it couldn't get network access)
After install, this card still wouldn't work, so I performed a full "yum update" using the USB card and rebooted into the current kernel.
I now have network access using the onboard RTL card, but I observe the following oddities:
My router, a Juniper Netscreen 5GT (with a 4-port 100/Full switch) is reporting the link as:
ns5gt-adsl-wlan-> get int trust port phy
Port 1: link is up, 100 Mbps, auto negotiated to full duplex
ethtool, however, reports the link as up at 10Mb/Half Duplex.
# ethtool eth0
Settings for eth0:
Supported ports: [ TP MII ]
Supported link modes: 10baseT/Half 10baseT/Full
Supports auto-negotiation: Yes
Advertised link modes: 10baseT/Half 10baseT/Full
Advertised pause frame use: No
Advertised auto-negotiation: Yes
Supports Wake-on: pumbg
Current message level: 0x00000033 (51)
Link detected: yes
Regardless of what I try and force on the card via ethtool (I've tried forcing autoneg off, speed 100, duplex full etc) it won't display the same speed/duplex that the router says. Nor will it renegotiate.
# ethtool -r eth0
Cannot restart autonegotiation: Operation not supported
I know which device I trust to tell me what I'm actually negotiated at, and it's not at the Linux end of the cable :o)
Incidentally, I find it a little odd that neither mii-tool or ethtool want to advertise 100/Full.

As you know, this module does not work properly on 1000Mb/s too.
There're several reports on this problem, but apparently nothing is being done to solve it.
Today, upgraded the kernel to kernel-PAE-126.96.36.199-149.fc13.i686 (and x86_64) but still the interface does not work correctly.
What should we expect this situation? There will be no solution?
Thanks for any info relevente.

This message is a reminder that Fedora 13 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 13. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '13'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 13's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 13 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
Fedora 13 changed to end-of-life (EOL) status on 2011-06-25. Fedora 13 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
