Hi Gagandeep,

There is an option(dec_ttl) in 'struct rte_security_ipsec_sa_options' to control this. Wouldn't that work?

Thanks,
Anoob

Subject: [EXT] query regarding IPsec inner IP header TTL

________________________________________
Hi,

Is there any option available in IPsec mode to decrement the inner IP header TTL field by security engine?

I believe in case of forwarding, inner IP header TTL should be decrement but not in case of packet termination. So looking for an option that application can pass to driver to perform TTL decrement.

Thanks,
Gagan
