Subject:When does Kismet capture packets?

That was clear for me (https://www.kismetwireless.net/Forum/General/Messages/1262620322.024545). But now I have to argue why, and I would like to know some things in order to explain it:

Kismet captures via pcap, which attaches to the kernel/driver layer.

Injection in general is super sketchy, uses different headers, etc. If you're using drivers which dump rtap but inject rtap-variant, straight dot11, or something else, it's not going to capture right since it won't match the declared DLT.
