Realtek r8169 & ethtool

[wj313]

Binary package hint: linux-image-2.6-386

Hi forum,

 network settings with "ethtool" doesn't seem to affect the "r8169" kernel module.

 Plattform testet: Dapper, Gutsy (Tribe2)
 Kernel versions testet: 2.6.17-10, (and the one from Gutsy)
 ethtool versions testet: 3, 5
 r8169 driver versions testet: 2.2LK, 6.001.00 (compiled from the realtek homepage)

 We've tried almost all combinations of above versions/plattforms.

 Is there any workaround to set the speed/duplex/autoneg settings of the r8169 driver?

 (mii-tool and parameters specified at the "insmod" command line of the r8169 driver doesn't work either..)

Just for the record:

 It's strange, but it does work if the parameter "autoneg off" is appendend to _every_ ethtool command.

 So, "ethtool -s eth0 speed 100 duplex full autoneg off" does work,
 "ethtool -s eth0 speed 100" does not.

Thank you for taking the time to report this bug and helping to make
Ubuntu better. You reported this bug a while ago and there hasn't been
any activity in it recently. We were wondering is this still an issue
for you? Can you try with latest Ubuntu release? Thanks in advance.

thanx a lot, wj313 !

Same here - on two 8.04 machines, kernels

2.6.24-19-generic #1 SMP Wed Aug 20 22:56:21 UTC 2008 i686 GNU/Linux

and

2.6.24-19-server #1 SMP Sat Jul 12 00:40:01 UTC 2008 i686 GNU/Linux

not the best idea to take out the media option support from r8169 while ethtool support doesn' work properly :-))

[Andreas Moog (ampelbein)]

Have you had a chance to try out with a recent kernel?

[Eckart Haug (ubuntu-syntacs)]

Works with 2.6.24-23-generic, e.g.

ethtool -s eth1 speed 100 autoneg off.
Autonegotiation standard is on and will immediately switch back to 1000.
-> switch autoneg off to keep non standard settings.

Best place for permanent setting is /etc/network/interfaces

e.g.

auto eth1
        iface eth1 inet dhcp
       post-up ethtool -s eth1 speed 100 autoneg off

Thanks. Closing the report then.
