bonding info reports wrong speed

New machine, stock 10.04 LTS 64bit build.

apt-get upgrade/update etc.

apt-get install linux-headers-server-lts-backport-natty linux-image-server-lts-backport-natty ifenslave ethtool

And finally, the wrong info from ifenslave (Speed: 100Mbps)

root@newsztcjptnfs03:~# cat /proc/net/bonding/bond0
Ethernet Channel Bonding Driver: v3.7.0 (June 2, 2010)

Bonding Mode: load balancing (round-robin)
MII Status: up
MII Polling Interval (ms): 0
Up Delay (ms): 0
Down Delay (ms): 0

Slave Interface: eth4
MII Status: up
Speed: 100 Mbps
Duplex: full
Link Failure Count: 0
Permanent HW addr: 68:05:ca:05:6f:4b

Slave Interface: eth5
MII Status: up
Speed: 100 Mbps

In short, I believe ifenslave can't handle 10Gig interface speeds?

Status changed to 'Confirmed' because the bug affects multiple users.

[Bryan Quigley (bryanquigley)]

Is this still an issue for you?

[Stéphane Graber (stgraber)]

Moved to linux, ifenslave only tells the kernel to create the bond, if the reported speed is wrong, it's a kernel bug not a userspace one.

[Joseph Salisbury (jsalisbury)]

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.14 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.
