    DNS: WKS RR Protocol field is read as 4 bytes instead of 1
    
    In the attached pcap file, there's a single DNS packet with WKS RR in the Prerequisites section.
    The Protocol field of this RR is read as if it is 4 bytes long instead of 1, which actually reads part of the bytes of the following RR.
