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.
