15.3. Configuring an ethtool coalesce setting by using nmcli

You can use NetworkManager to set ethtool coalesce settings in connection profiles.

Procedure

For example, to set the maximum number of received packets to delay to 128 in the enp1s0 connection profile, enter:
```
# nmcli connection modify enp1s0 ethtool.coalesce-rx-frames 128
```
For a list of settings you can configure, see the ethtool setting section in the nm-settings-nmcli(5) man page on your system.
To remove a coalesce setting, set it to a null value. For example, to remove the ethtool.coalesce-rx-frames setting, enter:
```
# nmcli connection modify enp1s0 ethtool.coalesce-rx-frames ""
```
To reactivate the network profile:
```
# nmcli connection up enp1s0
```

Verification

Use the ethtool -c command to display the current offload features of a network device:
```
# ethtool -c <network_device>
```
