I'm upgrading my production servers from Ubuntu 14.04 => 18.04 and running into a lot of surprising changes. For example, I'm trying to permanently disable TSO & GSO using ethtool and can't find either
/etc/network/interfaces which used to be there in 14.04 and is also mentioned in this link
How do I achieve this via
netplan which seems to be the shiny new way of setting up network infra in Ubuntu 18.04?
