Yes I know that, obviously:)

The point here is that nfnl_rcvbufsiz() has been advertised in the main page of
libnetfilter_queue HTML for a long time and there are likely a number of systems
out there that use it. When libnfnetlink is removed, libnetfilter_queue will
have to provide nfnl_rcvbufsiz() or those systems will start failing.

I have in mind that although libnetfilter_queue will provide nfnl_rcvbufsiz(),
there will be no documentation for it.

You will see in
I replaced the advice to use nfnl_rcvbufsiz() (in 2 places) with advice to use
setsocketopt(). I only mentioned that programs calling nfnl_rcvbufsiz() will
continue to run.

So I offered this patch as the only documentation of how to use
nfnl_rcvbufsiz(). I need it for my testing, but it's fine with me if you don't
want to take it.

Cheers ... Duncan.
