Target Milestone --- 

The performance of L3FWD has decre=
ased by 20% on Ubuntu 24.04, which is normal
on Ubuntu 22.04.

dpdk-devbind.py --force --bind=3Dvfio-pci 0000:31:00.0

2.Start L3FWD as the following command:
dpdk-l3fwd -l 5-8 -n 8 --force-max-simd-bitwidth=3D512 -- -p 0x1 --config=20
'(0,0,5),(0,1,6),(0,2,7),(0,3,8)' --tx-queue-size 2048 --rx-queue-size 2048

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

4.Actual Result.
| Fwd_core | Frame Size | Throughput
| 4C/4Q    | 64         | 90 Mpps=20

5.Expected Result.
it's passed on Ubuntu 22.04 (Kernel: 5.15.0-102-generic)
