hi, 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?
