Wireshark-dev: Re: [Wireshark-dev] [PATCH] ISIS Checksum

Hi,

   Of course that's why you review the patches! And I haven't said
anything about this review. You, guys, are the "wireshark experts" and
you know better than me the potential side effect(s) of a particular patch.
But I'm sorry to try to glean some additional information because *I*
didn't get to the point with the information I knew
*and* the information *you* gave (what is the exact meaning of more
common part CDP and less common ISIS?). At least Joerg had answered with
more than a "for now? yes." and gave useful information I didn't know
even if it does not entirely fulfill my expectations. CDP may be
partially implemented by a few others vendors than Cisco. The only case
I knew was riverstone which implements a CDP but I think it's not even
able to interoperate with the Cisco one.



Regards,

Sebastien Tandel
