Siginificance of pinfo->fd->flags.visited

[Vishnu Bhatt <vishnu.bhatt () aricent com>]

Hello all,

Can anyone please explain me the significance of pinfo->fd->flags.visited. I know that this variable is set to TRUE if 
a packet has been visited once but if we click on the same packet then why all things are done again? Logically if a 
frame has been dissected once, it should not be checked again, so condition "if(pinfo->fd->flags.visited == FALSE)" 
should always be checked before doing the dissection. Why the need of re-dissecting the frame over and over again?

My second doubt is that in RLC, if duplicity has already been checked then why to check it again? I mean should the 
duplicity function be covered under "if(pinfo->fd->flags.visited == FALSE)"?


Thanks
Vishnu Bhatt
