--
The NHRP dissector incorrectly decodes the cleartext password used in the NHRP
Authentication Extension - see the attached capture -
The first 4 bytes are decoded as an a Source Address when in fact they are the
first 4 bytes of the password, the second four bytes are displayed as just data
- when they should be displayed as a password.
