pub fn decode_options(data: &[u8]) -> Result<Vec<NdpOption>>Expand description
Decode a run of options.
RFC 4861 §4.6: “Nodes MUST silently discard an ND packet that contains an option with length zero.” That is not pedantry — a zero length is an infinite loop in a naive walker, and it is how a malicious neighbour wedges a stack.
