Detailed Description
Parse an Radiotap header.
Parser implementing the Radiotap header
Radiotap requires that all fields in the radiotap header are aligned to natural boundaries. For radiotap, that means all 8-, 16-, 32-, and 64-bit fields must begin on 8-, 16-, 32-, and 64-bit boundaries, respectively. In this way, generators and parsers can avoid unaligned accesses to radiotap capture fields. Radiotap-compliant generators must insert padding before a capture field to ensure its natural alignment.
