Compiled (64-bit) with GTK+ 2.22.1, with GLib 2.26.1, with WinPcap (version
unknown), with libz 1.2.5, without POSIX capabilities, without libpcre, without

Running on 64-bit Windows 7 Service Pack 1, build 7601, with WinPcap version
4.1.2 (packet.dll version 4.1.0.2001), based on libpcap version 1.0 branch

Discovered while working on Pcap.Net (http://pcapdot.net).
Looking at RFC 5568 (http://tools.ietf.org/html/rfc5568#section-6.4.3), it says
that the Link-Layer Address (LLA) Option, should have an address right after
the option code.
In Wireshark, in the attached example, you can see that it says:
Link-layer address: 86:f2:70:7b:be:0e:99:cc:86:be:8d:be:e3:06
While the byte after the option code is 0x88 and not 0x86.
I believe the correct Link-layer address should be:
88:86:f2:70:7b:be:0e:99:cc:86:be:8d:be:e3.
Thanks,
Boaz.
