Donnerstag, Dezember 18th, 2025TCP 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
