NAME

       pcap-linktype - link-layer header types supported by libpcap

DESCRIPTION

       For  a  live  capture  or  ``savefile'',  libpcap  supplies,  as  the  return value of the
       pcap_datalink(3PCAP) routine, a value that indicates the type of link-layer header at  the
       beginning  of  the  packets  it  provides.  This is not necessarily the type of link-layer
       header that the packets being captured have  on  the  network  from  which  they're  being
       captured;  for  example,  packets from an IEEE 802.11 network might be provided by libpcap
       with Ethernet headers that the network adapter or the  network  adapter  driver  generates
       from  the  802.11  headers.   The  names  for  those  values  begin with DLT_, so they are
       sometimes called "DLT_ values".

       The values stored in the link-layer header type field in the savefile header are, in  most
       but  not  all  cases,  the  same as the values returned by pcap_datalink().  The names for
       those values begin with LINKTYPE_.

       The   link-layer   header    types    supported    by    libpcap    are    described    at
       https://www.tcpdump.org/linktypes.html.
