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 ex-
       ample, 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
       http://www.tcpdump.org/linktypes.html.
