  Kernel version: 4.4.0-98-generic
  Kernel snap: caracalla-kernel version:4.4.0-98.121-1 revision:58
  BIOS version: 01.00.05 (Also tested with 01.00.03)
  Tested SKU: T, Media, GPA

  The reproduce steps:
  1. Enable Wowlan and Wol in BIOS
  2. Boot up Ubuntu core
  3. Connect to Wifi AP
      $ nmcli d wifi connect <my ssid> password <my password>
  4. Enable wowlan
      $ sudo iw phy phy0 wowlan enable magic-packet
  5. Enter suspend or hibernate
      $ sudo systemctl suspend
      or
      $ sudo systemctl hibernate
  6. Send wake signal from another machine
      # wakeonlan <Wifi MAC>
      or
      # sudo etherwake <Wifi MAC>
  7. If system not waked, try to wol or other wake source
      # wakeonlan <Ethernet MAC>
  8. After resume, check the wifi/BT function, but not functioning.
      $ nmcli dev
          DEVICE TYPE STATE CONNECTION
          eth0 ethernet connected Wired connection 1
          wlan0 wifi disconnected --
          eth1 ethernet unavailable --
          cdc-wdm0 gsm unavailable --
          lo loopback unmanaged --
      $ nmcli dev wifi rescan
      $ nmcli dev wfii list
      No wifi APs found

      $ sudo bluetoothctl
          [NEW] Controller 00:23:A7:EA:65:64 0225399 [default]
          [bluetooth]# power on
          Failed to set power on: org.bluez.Error.Failed

  The not functioning issue can be fixed by reload driver.
  Also hibernate wakeup fails, and wake by other wake source. The Wifi/BT still 
functioning which could be the FW is reloaded by driver.
