This issue was affecting my Asus N53SV Laptop with "RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller"
It seemed to be more likely to happen after suspend if I had put everything into low power mode with powertop, but I'm not certain about powertop's influence.
I've just dist-upgraded to the new kernel 4.15.0-24-generic and I've tested putting everything into low power mode with powertop, suspending and resuming, and the network adapter is working now.
4.15.0-24-generic resolved the problem for me.
