Perhaps you should look at ebtables. This can filter by Ethernet frame type or layer 3 protocol.

I want to know the method to catch packets at the device.
Essentially, I want to filter packets based on the types(I have a
custom header with type in that) at the interface rather than doing
the same at the network layer. One can use netfilter hooks to capture
packets at network layer; is there any way to mangle them at the
interface itself?
Thank you
