net::rawip source code question

Hello!
I'm a total newbie in perl. I examined some scripts where the net::rawip
module
was used. What does the following mean ?

$s = new Net::RawIP;
$filter = "ip proto \\tcp and src host $daddr and src port $dport";
$pcap = $a->pcapinit($device,$filter,1500,60);
....

So I'm trouble with the $filter line. (daddr = destination address,
dport=destination port).
Please explain this to me! Thanks in advance,
regards,
august

I answered the same question you posted on comp.lang.perl.modules.
Please do not multi-post.
