Hi David, Thanks for your reply!
BTW, I think there is another typo in tcpdump manual (https://github.com/NetBSD/src/blob/2b4e1229717fc755b0a69b2e318bba92c542e5e1/external/bsd/tcpdump/dist/tcpdump.1.in#L278): > a number and an interface name, possibly followed by a text description of the interface, is printed. I think it should be: > a number and an interface name, ...., are printed. I submitted bug report before (https://gnats.netbsd.org/cgi-bin/query-pr-single.pl?number=54943), but seems no one responded. On 2020/2/17 6:50 AM, David H.
