When i Capture DHCP Packet, each DHCP Packet has this in following specified
GUID Error.

I have an VM in this reproduce case with GUID (shown on PXE boot and in byte
packets:

Shown in VM: 564dca43-34d6-13e6-fbcd-c64ada957a
Shown in Wireshark: 43ca4d56-d634-e613-fbcd-c64ada957af9

The First Part of the GUID is rotated, this Bug is as far in each Wireshark
version i have used. :(
