Bug description:
  After a fresh install of Ubuntu 16.04.2 with 4.4.0-70-generic, the
  Mellanox Technologies MT27500 Family [ConnectX-3] card is detected,
  brought up and assigned an ip via MAAS. This is where functionality
  stops on this kernel. Pinging the MAAS server  which is connected
  directly(no switch) fails. There's no traffic  from tcpdump.

  linux-image-generic-hwe-16.04 4.8.0.44.16 fails
  mainline kernel 4.10.0-041000-generic fails
  mainline kernel 4.11.0-041100rc1-generic resolves the issue.

  Both the test server (ppc64le) and MAAS server(amd64) need the
  upgraded kernel to work.

  === 4.4.0-70-generic ===
