> We should probably fix the issue in the cmdline library to bring cmdline_poll() on parity with cmdline_interact(), but this is a decent workaround to avoid breaking those automation scripts that rely on Ctrl+D behavior.

This workaround works only when disabling softnic.
It means:
	1/ softnic usage is not fixed
	2/ we need to disable softnic for all other usages

I think it is not good enough.
