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.

Title:
  bonding info reports wrong speed

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  New machine, stock 10.04 LTS 64bit build.

  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 queue ID: 0

  Slave Interface: eth5
  MII Status: up
  Speed: 100 Mbps
  Duplex: full
  Link Failure Count: 0
  Permanent HW addr: 68:05:ca:05:6f:4a
  Slave queue ID: 0

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