I read somewhere that you don't need to do > this and just wanted to confirm that this is correct. Indeed, mlx5 PMD runs on top of mlx5 kernel driver. We don't need UIO or VFIO drivers. The kernel modules must remain loaded and can be used in the same time. When DPDK is working, the traffic goes to the userspace PMD by default, but it is possible to configure some flows to go directly to the kernel driver. This behaviour is called "bifurcated model". > On Mon, Feb 21, 2022 at 11:45 AM Aaron Lee <acl049@ucsd.edu> wrote: > > > Hi Thomas, > > > > I tried installing things from scratch two days ago and have gotten > > things working!

I see in the usage example in the docs, I could pass in --rxq=2 --txq=2 to set the queues to 2 each but I don't see that in my output when I run the command. Below is the output from running the command in https://doc.dpdk.org/guides/nics/mlx5.html#usage-example. Does this mean that the MCX515A-CCAT I have can't support more than 1 queue or am I supposed to configure another setting?
