I had the same issue with a e1000e on Ubuntu 18.04.1, 4.15.0-36 kernel and nothing helped. I've updated the driver directly from intel to 3.4.2.1-NAPI, without any improvements. All things listed in this and the other thread did not help. Guessing from reading through this Ubuntu bug report I have figured as a workaround to significantly reduce the ringbuffer size:
sudo ethtool -G eth0 rx 256 tx 256
This solves the problem completely for me and appears to not impact performance at all (Desktop use, only did basic benchmarks).
