Hardware x86
OS Linux
Status UNCONFIRMED
Severity normal
Priority Normal
Component testpmd

Steps to reproduce

1.create vfs and bind to vfio-pci
echo 1 > /sys/bus/pci/devices/0000\:31\:00.0/sriov_numvfs
echo 1 > /sys/bus/pci/devices/0000\:4b\:00.0/sriov_numvfs
ip link set ens85f0 vf 0 spoofchk off
ip link set ens85f0 vf 0 trust on
ip link set ens93f0 vf 0 spoofchk off
ip link set ens93f0 vf 0 trust on

./usertools/dpdk-devbind.py -b vfio-pci 31:01.0 4b:01.0=20

2.start testpmd with io fwd
dpdk-testpmd -l 5,6,7 -n 8 --force-max-simd-bitwidth=3D512 -- -i --txq=3D2 =
--rxq=3D2

EAL: Detected NUMA nodes: 2
EAL: Detected static linkage of DPDK
EAL: Multi-process socket /var/run/dpdk/rte/mp_socket
EAL: Selected IOVA mode 'VA'
EAL: VFIO support initialized
EAL: Using IOMMU type 1 (Type 1)

3.Start transmit traffic from ixia.
transmit rate: 100%
frame size: 64
IP/fixed dst, ramdom src

4.Actual Result.
| Fwd_core | Frame Size | Throughput
| 2C/2T    | 64         | 80.7 Mpps=20

5.Expected Result.
| Fwd_core | Frame Size | Throughput
| 2C/2T    | 64         | 87.9 Mpps=20

6. DPDK Bad commit.
