[dpdk-users] Round-robin packet distribution

[Tom Barbette]

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.
