I am trying to understand what happens when I put on mac in monitor mode. Without the monitor mode, using ifconfig, I find that 'en0' is the active interface. However, in monitor mode, this is what I get:

```

I am trying to use scapy for sniffing wireless network. So, when I run scapy, it shows iface as 'lo0' and it does not capture any packet. I have looked at a lot of answers regarding this, but most of them are for ubuntu and say that when you put your system in monitor mode, you get 'mon0' interface and then pass this to your scapy and sniff. But in mac, I am not getting anything like the 'mon0', in fact all the interfaces goes inactive in monitor mode. Could some one please help me understand what is happening?

PS: WireShark and Tcpdump work just fine in monitor mode and scapy too captures frames when not in monitor mode. But I am interested in management frames, so I need scapy to capture those on monitor mode. TIA:)
