Hello libpcap team,

Yes exactly each packet is an event. The layout of the event is 
https://docs.microsoft.com/en-us/windows/win32/api/evntcons/ns-evntcons-event_header and 
https://docs.microsoft.com/en-us/windows/win32/api/evntcons/ns-evntcons-event_header_extended_data_item. But we aligned 
this format with the ETL (serialization use by microsoft) which is not well documented.

Thanks in advance to take care about our request.

Have a nice day,

Sylvain

I would like to request you to get a DTL value for the PR
https://github.com/the-tcpdump-group/libpcap/pull/934.
This PR intend to add ETW capture for libpcap.
So is each packet an Event Tracing for Windows:
        https://docs.microsoft.com/en-us/windows/win32/etw/event-
tracing-portal
record of some sort?  If so, where is the format of that record
defined?
