11.2. Permanently setting an offload feature
If you have identified a specific offload feature that limits the performance on your host, you can permanently enable or disable it, depending on its current state.
If you permanently enable or disable an offload feature, NetworkManager ensures that the feature still has this state after a reboot.
Prerequisites
- You identified a specific offload feature to limit the performance on your host.
Procedure
Identify the connection profile that uses the network interface on which you want to change the state of the offload feature:
# nmcli connection show NAME UUID TYPE DEVICE Example a5eb6490-cc20-3668-81f8-0314a27f3f75 ethernet enp1ss0 ...Permanently change the state of the offload feature:
# nmcli connection modify <connection_name> <feature> <on|off>For example, to permanently disable IPsec Encapsulating Security Payload (ESP) offload in the
Exampleconnection profile, enter:# nmcli connection modify Example ethtool.feature-esp-hw-offload offFor example, to permanently enable accelerated Receive Flow Steering (aRFS) filtering in the
Exampleconnection profile, enter:# nmcli connection modify Example ethtool.feature-ntuple on
Reactivate the connection profile:
# nmcli connection up Example
Verification
Display the output states of the offload features:
# ethtool -k enp1s0 ... esp-hw-offload: off ntuple-filters: on ...
