[dpdk-users] simplest way to prioritize one of 128 Tx queues

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
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.
