[VPP-2117] vpp crash when enable nat on aarch64 architecture cpu under pressure test

[vvalderrv]

Description

I use vpp 20.05 and dpdk 20.02 on aarch64 architecture cpu server, and do a pressure test by using iperf3, the traffic is over 300MB. 

The problem I currently have is:     

(1) when I enable NAT feature, vpp crashes quickly, which runs fine in x86 architecture cpu.

(2)when I only using bond and policy routing, vpp runs fine.

(3) I also tried vpp version 2101, the same problem occurs. But in version vpp 2202, the problem not exists anymore.

 

 I think this crash is related to ARM or multi-thread or both of them
