It seems to only be a wired Ethernet issue.  I added Wifi.  Wifi
consistently reconnects as expected; Ethernet consistently fails.

Before suspend, `nmcli d`:
DEVICE  TYPE         STATE          CONNECTION 
enp9s0  ethernet  connected  Ethernet1  
wlp8s0  wifi            connected  NETBEAR-5G 
lo           loopback  unmanaged  --         

After resume, `nmcli d`:
DEVICE  TYPE         STATE                                                           CONNECTION 
wlp8s0  wifi            connected                                                   NETBEAR-5G 
enp9s0  ethernet  connecting (getting IP configuration)  Ethernet1  
lo            loopback  unmanaged

Is this a hardware incompatibility issue?

Title:
  Network Manager wired Ethernet stuck in "getting IP config" after
  resume from suspend

Status in network-manager package in Ubuntu:
  New

Bug description:
  Stopping and starting the Network Manager did not work-around this
  issue.  Only a reboot or power off+on gets wired Ethernet back into
  service.

  Note: I did not try hibernate nor using wireless.
