Ubuntu Bionic 18.04 LTS:
We found that default bionic kernel 4.15.0-46-generic doesn't support ethtool -C adaptive-tx
Our ethernet card is Mellanox Connect4-Lx and Connect5, and this will affect performance of latency sensitive workloads like memcached.
Maybe we should backport adaptive-tx support to kernel 4.15 LTS?
