- /*
- * FIXME: rather than the above conditional, here could
- * be a nice generic mechanism to extract two L4 values:
- *
- * have a per-protocol array of 4 elements like this:
- * u8 offset; to take the byte from, off L4 header
- * u8 mask; to mask it with, before storing
- *
- * this way we can describe UDP, TCP and ICMP[46] semantics,
- * and add a sort of FPM-type behavior for other protocols.
- *
- * Of course, is it faster ? and is it needed ?
