encapsulation with an "MTP2 plus pseudo-header" encapsulation. Get rid
of "rawss7.h", as the LINKTYPE_RAWSS7 it's mainly dedicated to explain
was never implemented. Update savefile.c for the changes.
value arguments are to other routines. Do the same with the value
argument to "gen_atmfield_code()".
"gen_load_a()" can return more than one statement; append to the list of
statements it returns with "sappend()", rather than manually appending
to the first statement.
Fix the argument list to one "gen_ncmp()" call, and get rid of the casts
in the other calls, as the arguments already have the right types.
Fix the casts in calls to "gen_atmfield_code()".
takes an argument indicating what the offset is relative to.
Make the various comparison generators take an argument of that sort as
well.
Tweak the arguments to "gen_ncmp()" to match those of the other
comparison routines, and make all the other comparison routines just
call "gen_ncmp()".
of the link-layer, network-layer, and transport-layer (assuming the
network layer is IPv4) headers. This makes it a bit clearer what stuff
would be changed for variable-length link-layer headers or
variable-length pseudo-headers before the link-layer header.
whether it succeeds or fails, so you can't erase a "no" result and try
again with a different header. Use AC_CHECK_DECL, which doesn't define
HAVE_DECL_xxx, and then explicitly define it based on whether we found a
declaration or not.
don't have __attribute__ support in the compiler.
While we're at it, get rid of the declaration of bpf_error() in
gencode.c, as it's already declared in gencode.h.
routines, including malloc() and company - and for string routines used
in this file, which aren't necessarily declared in <memory.h>, so
include <string.h>.
on HP-UX, just keep trying different SAPs until we find one that doesn't
return EBUSY, as attempting to use a SAP that some other descriptor is
already bound to returns EBUSY.
What it does includes checking whether the packet is of the type
specified by the <proto> argument, so there's no need to add such a
check when checking whether the ISO protocol type field has a particular
value; remove the extra check against the ISO protocol.

"gen_ether_linktype()" and "gen_linux_sll_linktype()", as well as
"gen_linktype()".
Add comments for those routines to indicate how they handle the protocol
type argument.
In "gen_linux_sll_linktype()", merge together the handling of
LLCSAP_ISONS, LLCSAP_IP, and LLCSAP_NETBEUI, as was done in
"gen_ether_linktype()" and "gen_llc_linktype()".
Merge the code to handle the LLCSAP_ISONS, LLCSAP_IP, and
LLCSAP_NETBEUI.
"gen_ether_linktype()" already handles SAPs as protocol IDs; just use it
for Ethernet, rather than using "gen_llc()" (which isn't prepared to
handle Ethernet, with off_linktype pointing to the type/length field
rather than the DSAP).
That also means that "gen_linktype(LLCSAP_ISONS)" can be used to test
for OSI packets on Ethernet.
Expand some comments.
Fix a typo ("off_nl = +4" should've been "off_nl += 4").
by checking the proto against the ethermtu and bumping
the link-layer offset by two.
-add support for vlan and mpls hierarchies by not absolute
setting offsets but rather incrementing them;
example(s):
mpls 100000 && mpls 1024
=filters for outerlabel 100000 and inner label 1024
vlan 100 && vlan 200
=filters for vlan 200 encapsulated withing vlan 100
vlan 300 && mpls 17
=filters for mpls label 17 encapsulated in vlan 300
<netinet/ether.h> declares ether_hostton(), so the failure to find it
declared in <netinet/in_ether.h> doesn't cause us to assume we won't
find it anywhere.
