Hello,
I would like to ask for help with understanding global-total virtual point for queue. As I understand, it is combination of global-in (placed after prerouting) and global-out (placed after postrouting, before interface outputs).
In case that there is a queue placed in global-in (parent=global-in) and packet is marked with relevant mark, packet goes into this queue. Second queue is placed in global-out, packet marked with relevant mark for second queue qoes into this queue. Ie, one particular packet goes twice in queue (in case of relevant marks in relevant places) during his way through chain.
What is the situation in case of queue placed in global-total? Packet goes into this queue only once (there is some flag “already queued” glued to packet?) or packet qoes into this one queue again twice (in case of relevant marks in relevant places)?
Thanks
