I am also having the same problem in Ubuntu 18.04.1 with multiple network interfaces getting renamed consistently after reboots and complete shutdowns. All four network interfaces are from an Intel I350 device built into a Supermicro X9DRI-LN4F+ motherboard. Only 1 interface of the 4 is named eno1 the other 3 are a variation of renameX and all 4 interfaces are consistently switching names or getting new and higher numbered renameX which then screws up my network configuration for this machine.
