Hi Experts,
It worked after making the following changes. I enabled "crypto_native_plugin"
& qat in startup. If this is a real issue and if my Crypto/QAT config is
correct, I can submit this fix for review. Please let me know.

Subject: Re: [vpp-dev] IPSec/QAT offload config
Once more than 1 worker core is added in startup conf, crash is not observed
during init phase. But when I set the async mode on, it crashes in same place.
Do I need to set async mode on to use QAT ? Do I need to enable any specific
plugin ?
