Have you tried to use netfilter hooks?
For receiving of packets(from kernel to userspace), this is a good option.

I need to capture the data from an NIC. Instead of pushing it into the network stack, I'll make it to store them in a kernel ring buffer. From that buffer, a user space application will read the raw packet, do the necessary processing and send it back. As you can see I'm looking towards to transfer chunks of data to and from userspace. So, which method does suit well here? Jinesh. -- Kernelnewbies: Help each other learn about the Linux kernel.
