[dpdk-dev] [PATCH v5 0/6] integrate librte_ipsec SAD into ipsec-secgw

[Akhil Goyal]

> 
> This series integrates SA database (SAD) capabilities from ipsec library.
> The goal is to make ipsec-secgw RFC compliant regarding inbound SAD.
> Also patch series removes hardcoded limitation for maximum number of SA's
> and SP's.
> According to our measurements, after this series of patches,
> ipsec-secgw performance drops by about 0-2%.
> 
> v5:
>  - introduce SAD cache to solve performance degradation
>  - ipsec_sad_add() returns an error if the key is present
> 
> v4:
>  - put tunnel SA's into SAD with SPI_ONLY type for performance reason
> 
> v3:
>  - parse SA and SP into sorted array instead of linked list
> 
> v2:
>  - get rid of maximum sp limitation
> 
> Vladimir Medvedkin (6):
>   ipsec: move ipsec sad name length into .h
>   examples/ipsec-secgw: implement inbound SAD
>   examples/ipsec-secgw: integrate inbound SAD
>   examples/ipsec-secgw: get rid of maximum sa limitation
>   examples/ipsec-secgw: get rid of maximum sp limitation
>   examples/ipsec-secgw: add SAD cache

Hi Anoob,

Do you have any comments on this set. I do not see degradation on this patchset now.
