[dpdk-dev] [PATCH v2 6/6] examples/ipsec-secgw: clear soft expiry configuration

[Ananyev, Konstantin]

> 
> Soft expiry is not a mandatory IPsec feature. It is verified separately
> with IPsec unit tests. So configuration of the same is not required.
> Also, soft expiry tracking can cause perf degradation with some PMDs.
> Since a separate UT is available and the same setting in ipsec-secgw is
> not verifying the functionality, remove the same by clearing life
> configuration.

As a nit: as I can read the code it would be already zeroed at entrance to this function,
so explicit zeroing is not really required.
