forcedeth autoneg for 100M-FD fails

[Chris Hofstaedtler]

Wired network on this laptop fails to come up automatically on the work network.

After running this ethtool command, the wired network works, until the NIC gets turned off (say, suspend):
ethtool -s eth0 speed 100 duplex full autoneg off

Running the ethtool command above gives this info in dmesg:
[ 62.560356] forcedeth 0000:00:0a.0 eth0: link up
[ 62.560527] IPv6: ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.10 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Can't test 3.10 because the graphics driver won't compile.

OTOH, I don't see any suspicious changes since 3.8 in mainline git in the forcedeth driver.

[Chris Hofstaedtler (zeha)]

Did test with 3.10.0-999-generic_3.10.0-999.201307110431 (despite having no graphics and only a partially working VT), and the bug still exists.

Forcedeteh driver had issues with my NVIDIA Corporation MCP51 Ethernet Controller (rev a3) in ubuntu 13.10. Ethernet drops time after time and have to reset. It's a recurrent issue in the last versions. Maybe some change in the kernel.

[Luke J Militello (kilahurtz)]

I'm having a similar issue running 12.04 with the Trusty hardware enablement stack; kernel v3.13. I have the MCP51 controller and get random protocol flaps even with the physical link still up. This causes problems as I have an NFS auto mounted home directory. My only workaround has been to spawn a root shell on tty1 and reboot. In comment #6, when you say reset, are you referring to bouncing via ifconfig or reloading forcedeth? The next time this happens to me, I will try both and see what happens unless anyone else can comment on this issue with a workaround.

[Luke J Militello (kilahurtz)]

I did some research and discovered a solution to my problem. I reloaded the forcedeth module with msi=0 and msix=0. This solved my problem and this issue no longer plagues me.
