  There is a series of patches in this link that should resolve this issue. 
  http://permalink.gmane.org/gmane.linux.network/347777
  I had applied these in upstream kernel and it is ok but let me double check with Ubuntu 15.04 kernel if these are the patches we need to solve this bugzilla.

  I used this kernel from Ubuntu 15.04 3.18.0-13.14
  To make EEH work, to try to reach the first 2 patches of that series I have to use all this patches:

  So basically to apply the series will need a lot of patches and
  probably restest the driver.
