I thought that, too - however, it is no problem at all to compile your 
own 3.18 kernel on Ubuntu 16.04 and just install it - that is what we 
are currently running.

since Martin mentioned that he is using a generic driver, I guess that 
is OK - however, notice his hardware is probably also a high-quality, 
dedicated NIC via PCIe (e1000e) - the hardware of the ethernet 
device/NIC makes a big difference!
