Did this issue start happening after an update/upgrade?  Was there a
prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.1 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.

  Info:On session Unity Network applet figure online but internet is slow on 1Mbs to 0Mbs.
  Sometimes from applet set  enable/disable from many times to start normal but not allways have succed.
  Temporary i add on file on MetworkManager to solve this issue:
  $ cat /etc/NetworkManager/dispatcher.d/pre-up.d/01set_half
  #!/bin/sh -e
  # Script for setting halfduplex

  if [ -z "$1" ]; then
      echo "$0: error missing interface" 1>&2
      exit 2;
  fi

  /sbin/ethtool -s "$1" duplex half speed 100
