Dvorak David, this bug was reported a while ago and there hasn't been
any activity in it recently. We were wondering if this is still an
issue? If so, could you please test for this with the latest server
release of Ubuntu? ISO images are available from
http://releases.ubuntu.com/raring/ .

If it remains an issue, could you please run the following command in
the development release from a Terminal
(Applications->Accessories->Terminal), as it will automatically gather
and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.11-rc5

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.

Title:
  Precise - bonding without link aggregation

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I have two servers : server "A" with Ubuntu 10.04_amd64 and server "B" with fresh install Ubuntu 12.04_amd64. Server "A" has 4x Gigabit NIC (all in bond 802.3ad) and server "B" has 3x Gigabit NIC (all in bond 802.3ad). As switch is 802.3ad capable Cisco.
  Throughput to server "A" is OK - from one PC with Gigabit NIC is ~925 Mbits/sec, from two PCs (tested simultaneously) is still 2x ~925 Mbits/sec. Ethernet Channel Bonding Driver is v3.5.0 (November 4, 2008).

  But throughput to server "B" (with the same NIC interfaces
  configuration as server "A") is without link aggregation - from one PC
  with Gigabit NIC is ~925 Mbits/sec, from two PCs is 2x ~460 Mbits/sec,
  from three PCs is 3x ~305 Mbits/sec etc. With iptraf I see, that all
  port is working, but without link aggregation.
