Proxmox Virtual Environment (VE) – a specific bug where the Intel e1000e driver clashes with the new Linux kernel leading to network failure and „digital silence“

TCP offload is a feature that can be disabled at the driver level or at the hardware itself at the driver level if we want to disable TSO we run the ethtool -K command for which we received ‚function not implemented‘ then that means that the driver does not allow the feature to be disabled

To enable TSO for a network device eth0 issue:

# ethtool -K eth0 tx on sg on tso on

To disable TSO for a network device eth0 issue:

# ethtool -K eth0 tx off sg off tso off
