Hi Filip,
This is not possible, but you may use the idea of Sprayer
(http://www.gta.ufrj.br/ftp/gta/TechReports/SCC18d.pdf) to dispatch
packets randomly (use RSS on the checksum).
However, in our paper RSS++
(https://www.diva-portal.org/smash/get/diva2:1371780/FULLTEXT01.pdf) we
show it's nearly always a bad idea because you'll have to share state,
and even for "stateless" function, that leads to a very bad locality in
a firewall as the same rules have to be fetched to L1 to all cores at
the same time when you receive a burst of similar packets.

Hi,
Is there a way in DPDK to configure the NIC to distribute the incoming
packets to multiple queues in a round robin fashion? Without taking into
account the payload/headers or type of packet, just plain round robin
distribution to multiple queues.
I'm struggling to obtain a fair mechanism using RSS, perhaps the
rte_flow API can do the trick? Any other suggestion?
Thanks
