"libpcap error: BIOCSETIF failed: Device not configured" on FreeBSD

[rm1984]

Hi,
I get this error when running dnspeep on FreeBSD:

query name                           server IP            response
Error: Failed to start. This may be because you need to run this as root.

Caused by:
    libpcap error: BIOCSETIF failed: Device not configured

Location:
    src/main.rs:176:10

This is because FreeBSD doesn't support sniffing on the "any" interface.
Please add an command line option to indicate a specific network interface to listen on.

Cheers,
Riccardo
