PCAP-LINKTYPE(7)       Miscellaneous Information Manual	      PCAP-LINKTYPE(7)

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(3) 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 libp-
       cap  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
       http://www.tcpdump.org/linktypes.html.
