Hello,
I have a problem in my DPDK implementation,
I'm redirecting/filtering ingress traffic to a specific queue depending on the udp port using rte_flow.
Now that I have that I would like to redirect all non-matching packets to a specific queue.
How can I do that with RTE_FLOW ?
Thank you in advance for your answer.
Regards,
Antoine Pollenus

rte_flow supports INVERT as a pattern match. That is what you want.
Not all hardware supports it.

Just checked, unfortunately no driver supports this pattern item at the
moment.
Assuming the intent is to dedicate a queue or a set of queues to matching
traffic and a different set to leftover traffic *without* overlap between
the two, you can rely on priorities as a workaround:
- Rule with priority 0: match specific UDP ports and redirect that to a
specific queue (QUEUE action) or a group of queues (RSS action).
- Rule with priority 1: match everything (i.e. empty pattern) and spread
that into the remaining queues (QUEUE or RSS action depending on the
number of target queues).
