Hi everyone, I'm trying to implement a scheme that dedicates a high priority Tx queue for low-latency control traffic and up to 100 other rate-limited Tx queues for lower priority data traffic. There are only two priorities involved here. What would be the simplest setting on the Tx side?
Do I need to use the DCB or VT modes or can I simply go with DCB off, VT off but set the RTTDT1C register (credits to refill for queue after each round by arbiter?) for the high priority queue to a large number of credits relative to other queues? I want to be fair across all the 100 lower priority queues and I was worried that putting them in different traffic classes will prioritize one queue over another. Let me know if you have any thoughts, I'm just getting started with DPDK. Thank you, Lavanya
