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 ===
