I know that before capturing packets, I can select specific interface.

I wonder is there any filter to distinguish different interfaces after I capture packets?

That is, at the beginning, I capture packets of all interfaces.

After that, I can using "some filter" for different interfaces.

Does anyone know about it?

The "Linux cooked" capture mode doesn't distinguish in any way between packets from different interfaces. You can only filter the results by IP address.
