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
