I don't see the point of answering the guy if you're just going to tell him to take a flying leap; the answers are simple: PPP_DEFLATE: Needed to include the zlip deflate libs into the kernel, whether you're using PPP or not. PPP_BSDCOMP: This is a specific PPP option (BSD Compression), so you need to enable this only if you want it supported PPP_FILTER: Enables BPF ppp filtering. Its inefficient to pass every packet to the bpf filters when you have no intention of using them, so disabling this allows for a more efficient stream. Not too difficult.
