Now that I implement this for linux-generic, I realized this is
ambiguous: does disabling a lower layer's parsing means that the parser
stops looking into upper layers? Even if their parsing is enabled?
E.g. if (jumbo == 0 && ipv4 == 1), we won't parse the ethernet header if
it's a jumbo frame, that's fine. But do we continue to look into the
rest of the packet for the IPv4 header?
I would say no, but it should be mentioned here explicitly.
