I don't know if this is a regression or not, this laptop is brand new
and I have only ever had Trusty on it.

The same issue happens with the upstream kernel. When I plug in the wifi
dongle, this gets printed into dmesg:

Title:
  148f:5370 [MacBookPro11,1] Suspend breaks network

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  Using a 13 inch MBP Retina suspend the machine either by closing the
  lid or with the menu option. Then resume. All entries from the network
  indicator have disappeared. The only option selectable is "enable
  networking" but clicking on that has no effect. Network remains
  broken.

  I'm using an external USB Wifi dongle. The behavior is the same
  whether I unplug it before suspending or not.
