> Subject: [PATCH v3] cryptodev: add capabilities discovery mechanism
>
> From: Declan Doherty <declan.doherty at intel.com>
>
> This patch add a mechanism for discovery of crypto device features and
> supported crypto operations and algorithms. It also provides a method for a
> crypto PMD to publish any data range limitations it may have for the
> operations
> and algorithms it supports.
>
> The parameter feature_flags added to rte_cryptodev struct is used to capture
> features such as operations supported (symmetric crypto, operation chaining
> etc) as well parameter such as whether the device is hardware accelerated or
> uses SIMD instructions.
>
> The capabilities parameter allows a PMD to define an array of supported
> operations with any limitation which that implementation may have.
>
> Finally the rte_cryptodev_info struct has been extended to allow retrieval of
> these parameter using the existing rte_cryptodev_info_get() API.

> - Fixed incorrect values for sizes
> - Renamed some fields in capabilities structure
