[dpdk-dev] Bond port with multiple queues

[dpdk-dev] Bond port with multiple queues

[Sergey Balabanov]

Hello,

I configured a bond port with 2 rx queues on it and added 2 slaves into the 
bond port. When I run traffic I get all packets on queue #0. This is quite 
expected when RSS turned off. When I turn on RSS all packets are distributed 
between two rx queues. There is no guarantee that I will get all packets from 
the slave port #0 on some queue and all packets from the slave port #1 on 
another queue.
Does anybody know is there a way to configure bond port in a way when all traffic 
on port #0 goes to queue #0 and traffic on port #1 goes to queue #1?

Thanks,
Sergey Balabanov

Hey Sergey,

this is the behavior I would expect. The way we've implemented it the 
same RSS configuration will get applied to each slave, so in the case of 
say a fail over event in active backup mode as rx traffic is moved onto 
a new master the traffic flows will be directed to the same queues as 
before. If I understand what you are asking for I'm not sure why you 
need a bonded port, why not just used the 2 ports with a single queue 
each rather than a single bonded port with 2 queues?
