Error receiving from ethtool socket

Installed via `install.sh`

I get the following, regardless of args

```
┌──(kali㉿kali)-[/tmp]
└─$ sudo sanicdns -i majestic_million.txt --resolvers 1.0.0.1,8.8.8.8 -o /tmp/sanic.txt -w 4 --postfix .example.com
error: error:, channel_count error: Error receiving from ethtool socket

```

`ethtool` is installed

```
┌──(kali㉿kali)-[/tmp]
└─$ ethtool -h
ethtool version 6.10
```

Reproduce the reported command from the issue after installing with install.sh, using the same resolver and ethtool setup. Trace where the “channel_count” and “Error receiving from ethtool socket” messages originate; done means the command no longer fails for this environment or the issue is documented with a confirmed compatibility limitation.
