Hi all, I was capturing some DHCP relay to DHCP server traffic that uses some relay suboptions (one of them being suboption 6, see RFC 3993) using tcpdump on Linux. When I loaded the capture file in wireshark, noticed that suboption 6 is printed as 'invalid agent suboption (6), 4 bytes', for example. Since I was checking a DHCP relay implementation, I had to make sure that suboption6 is properly encoded, so I had a look at the wireshark code (0.99.6, I'll also check svn head) and noticed that any suboptions besides 1 (circuit id) and 2 (remote id) are treated as invalid suboptions. It looks like there are suboptions up to 10 defined so far (see http://www.iana.org/assignments/bootp-dhcp-parameters).
I'll try to come up with a patch against head, IMO the error message should at least be 'Unknown agent suboption', and known suboptions should be printed. If needed, I can provide a capture file that exhibits the problem.
