Comment # 3 on bug 9594 from Alexis La Goutte

Hi Ben,

The problem don't come from suboption don't start by 1 but from the Enterprise
number, in reply, the enterprise value is 4413 (and answer is 3561)

And Wireshark support only for the moment Enterprise value 3561

The small patch fix this issue :

But there is also the issue, no display data when it is a unknown enterprise..
