mmm, interesting, I was not aware about that.Hi, the ethtool fix works fine, and I've set-up a post-up action to run in each time eno1 is up.
But after adding a new network interface on one of my vm with the VLAN tag 20, the host freeze issue returns.
maybe can you use vlan-aware bridge ? (tag will occur on bridge, and no ethX.y interface will be created)
