  • Apr 22, 2010 · Netfilter hooks are very useful when you wish to intercept, and modify IP packets inside a kernel module. One great thing about using Netfilter hooks over say dev_add_pack() is that the bad L2 frames, and bad IP packets get filtered out earlier in the network stack so you only deal with good packets.
