Hi Thomas,
I was doing some more testing and wanted to increase the RX queues for the
CX5 but was wondering how I could do that. 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?
