by Wiretap, to indicate whether certain fields in that structure
actually have data in them.
Use the "time stamp present" flag to omit showing time stamp information
for packets (and "packets") that don't have time stamps; don't bother
working very hard to "fake" a time stamp for data files.
Use the "interface ID present" flag to omit the interface ID for packets
that don't have an interface ID.
We don't use the "captured length, separate from packet length, present"
flag to omit the captured length; that flag might be present but equal
to the packet length, and if you want to know if a packet was cut short
by a snapshot length, comparing the values would be the way to do that.
More work is needed to have wiretap/pcapng.c properly report the flags,
e.g. reporting no time stamp being present for a Simple Packet Block.

form of corruption/bogosity in a file, including in a file header as
well as in records in the file. Change the error message
wtap_strerror() returns for it to reflect that.
Use it for some file header problems for which it wasn't already being
used - WTAP_ERR_UNSUPPORTED shouldn't be used for that, it should only
be used for files that we have no reason to believe are invalid but that
have a version number we don't know about or some other
non-link-layer-encapsulation-type value we don't know about.

link" records, including stuff that's from a G.704 PRI frame but not
from a D or H channel in that frame. Handle them (currently, we ignore
them).
The low-order bit of the flags field for "packet" records" is "network
to user" (NT->TE), not "user to network" (TE->NT).

bytes of what we thought was a version string appears to be an 8-byte
record of some sort in the captures we originally looked at, and appears
to be a non-8-byte record in another capture. If we treat that as a
record, the version string field appears to be null-padded and 41 bytes
long.

a packet. Ignore records other than packet records.

software. More work is needed:
we don't know where the capture start time is yet;
we aren't handling the "stop capture" record;
we don't know where the ISDN channel is;
there might be non-ISDN file formats;
but this at least is easier than trying to text2pcap hex dumps from that
software into pcap files.
