Wireshark · Ethereal-dev: [Ethereal-dev] radius patch

[Joost Yervante Damad <Joost.Damad@xxxxxxxxxxx>]

Hi,

the following diff adds 3 new vendors, 3 non-encapsulated Merit vendor
specifics, displaying of the authenticator in the protocol tree and
possibility to display-filter on selected attributes:

User Name, NAS IP Address, NAS Port, NAS identifier, Called Station Id,
Calling Station Id

Greetings, Joost Damad
