"ethtool enp1s0" yields
     Supports Wake-on: pumbg
     Wake-on: d

Unfortunately I could not find any BIOS switch to enable WOL, but 
although not persistent, "ethtool -s enp1s0 wol g" works for 1 reboot. I 
issued that command in a session with kernel 4.18.18, rebooted and 
noticed that between shutdown and new boot the LAN port status LED 
turned off for 1s, then turn on again and network came up with a 4.19 
kernel which normally fails in this szenario.
