Wireshark · Ethereal-users: [Ethereal-users] decoding error for UMA message

["Pow Wanger" <wangpower@xxxxxxxxxxx>]

Hi
Please find the attached file.

The RAI is decoded wrongly as 603-1-62ff-78, but actually it should be 
decoded according the octects 13 00 62 ff 78 ff , which would result in 
310-26-65400-255.

Also for the TLLI decoding, it displays something called "Start Mode", I 
think it should display "TLLI" instead, also, normally TLLI is displayed in 
Hex in convention.
