After talking to kernel team it was decided it is better to wait for
Wily LTS kernel to enable this type of HW in Trusty, Utopic and Vivid.

Title:
  Ubuntu Trusty, Utopic and Vivid should support ConnectX-4 100Gbit
  Ethernet Driver per Mellanox request

Status in linux package in Ubuntu:
  Won't Fix

Bug description:
  Mellanox has contacted Canonical so we could include Connect-X 4
  support in kernels for Trusty, Utopic and Vivid. They have used Vivid
  kernel tree to backport their upstream patches and provided us the

  Since this is a huge list it might be appropriate to include those
  commits into Vivid and make Trusty depend on the Vivid HWE kernel for
  supporting ConnectX-4 (since that is what HWE kernel is all about).
