Mellanox VF failed to start with hairpin queues

[Haider Ali]

Hi,

Can anyone please guide me on why I am not able to do hairpin on VF? I am running the testpmd application with 1 Hairpin queue and 1 standard queue pair on Mellanox VF but getting following error:

$ sudo ./build/app/dpdk-testpmd -l 1,3 -n 4 -a 04:01.2 -- -i --rxq=1 --txq=1 --hairpinq=1 --hairpin-mode=0x00

EAL: Probe PCI driver: mlx5_pci (15b3:101e) device: 0000:04:01.2 (socket 0)
TELEMETRY: No legacy callbacks, legacy socket not created

testpmd: create a new mbuf pool <mb_pool_0>: n=155456, size=2176, socket=0
testpmd: preferred mempool ops selected: ring_mp_mc

Warning! port-topology=paired and odd forward ports number, the last port will pair with itself.
