implementation under the APSL license, I wonder if the community is
allowed to submit a pull request for it. Are there any restrictions or
guidelines we should be aware of in this regard?  Thanks for your time
and patience.

My understanding is that the APSL is not compatible with the BSD 2-clause.

The main problem with the APSL that I know of is the patent clause, which might mean that, if somebody uses APSLed code 
as a result of using libpcap to read or write pcapng files, their license to use it would terminate immediately and 
without notice if they file a patent lawsuit against Apple (unless they do so in response to an Apple patent lawsuit 
against them).

Not being a lawyer, I don't know whether the patent clause would apply to users of libpcap (or tcpdump, if we pick up 
any APSL-licensed code), or just to the Tcpdump Group (I suspect we're unlikely to apply for any patents).

See my longer email reply to the original message.
