Hello
I did experiments where I sent packets to the hairpin queues and the CPU
queue at the same time.
During testing, I found that when the CPU queue is overloaded too much,
the hairpin queues also begin to drop packets.
Example 1:
Sending 10 Gbps to hairpin queues
Resulting throughput is 10
Hi Dmitry,
Thank you for your helpful reply.
Try enabling "Explicit Tx rule" mode if possible.
I was able to achieve 137 Mpps @ 64B with the following command:
dpdk-testpmd -a 21:00.0 -a c1:00.0 --in-memory -- \
-i --rxq=1 --txq=1 --hairpinq=8 --hairpin-mode=0x10
Based o this I was able

Hello,
I want to use hairpin queues to forward high priority traffic (such as
LACP).
My goal is to ensure that this traffic is not dropped in case the
software pipeline is overwhelmed.
But during testing with dpdk-testpmd I can't achieve full throughput for
hairpin queues.
