isn't always very suggestive - for example, somebody might think
"EN10MB" is always 10 MB/s, and might not know that "IEEE802" is Token
Ring), using "pcap_datalink_val_to_description()". Supply our own
"pcap_datalink_val_to_description()" if libpcap doesn't have it (even if
it has "pcap_datalink_name_to_val()").
Young <dyoung@ojctech.com>, with some minor changes by Jason R. Thorpe
<thorpej@netbsd.org>, and further changes by me to:
use "-y" rather than "-D" to set the link type ("-D" was already
taken);
use libpcap APIs to map between data link type names and values;
supply stub versions of missing-but-needed libpcap APIs.
Update Jason Thorpe's e-mail address (Zembu is going away, if it hasn't
done so already).
the libpcap that comes with some platforms doesn't define it.
Check for "pcap_debug" and "yydebug" in libpcap in the configure
scripts, so that whichever one is present (which might depend on whether
libpcap was built with standard YACC or Berkeley YACC/Bison), if any is
present, will be used by the "-Y" flag (if none is present, "-Y" won't
be supported).
DECnet support currently assumes certain conditions instead of
checking for them explicitly. The following code checks if
dnet_htoa() is available, possibly in libdnet and also verifies
there is no declaration for the function in <netdnet/dnetdb.h>
before it decides to provide a substitute.
Digital UNIX using "ip_vhl" rather than "ip_v" and "ip_hl" bitfields if
__STDC__ is defined (we have our own "ip.h", and we don't use bitfields
in it).
Get rid of HAVE_INET_ATON, HAVE_INET_NTOP, and HAVE_INET_PTON - we don't
use them; instead, we supply our own versions of "inet_aton()",
"inet_ntop()", and "inet_pton()". (Defining them in "configure.in"
caused complaints from "autoreconf".)
Check for the "rc5.h" header, as we *do* use HAVE_RC5_H.
"linux-includes/netinet/if_ether.h" to "ethertype.h".
Move other stuff used by dissectors from <netinet/if_ether.h> to
"ether.h", along the lines of "fddi.h" and "token.h".
Move ARP declarations from BSD include files to "print-arp.c".
Remove from dissectors includes of <netinet/if_ether.h>, and add
includes of "ethertype.h" and/or "ether.h" as necessary.
Get rid of configuration options that test declarations now made in
"ether.h" or "print-arp.c", as those declarations are now under our
control, not the OS's control.
