How to set promisc mode of a NIC in configuration.nix?

Help
1

I searched available options in nixos options, however, no related option.

Of course I can enable promisc mode in cmd line after booting
ifconfig eth0 promisc

But how can I make it presistent?

Thanks.

not sure there should be nixos options for such specific settings. You could try to write some nix in boot.postBootCommands

You might want to do this via udev and a systemd device unit to avoid potential race conditions if your network interface is initialized after the command is run.
