[mpls-linux-general] sniffing mpls-packets with ethereal

[Kauder T. <Tho...@ic...>]

Hi James,
I guess you know that there's a problem sniifing mpls-packets if the machine 
running ethereal is the destination of these packets. 
I posted a message to the ethereal-user-mailinglist and that's what I've got as
answer.

Maybe you can use that.
