Subject: Re: [dpdk-dev] [EXT] [PATCH v2] doc: announce change in crypto raw data vector
Date: Thu, 5 Aug 2021 14:04:25 +0000 [thread overview]
Message-ID: <CO6PR18MB4484CBE3D55E7F2302206587D8F29@CO6PR18MB4484.namprd18.prod.outlook.com> (raw)
In-Reply-To: <20210805135529.14146-1-hemant.agrawal@nxp.com>
> The current crypto raw data vectors need to be extended to support
> out of place processing. It is proposed to add additional desl_sgl
> to provide details for destination sgl.
> The same is also extended to support rte_security usecases, where
> we need total data length to know how much additional memory space
> is available in buffer other than data length so that driver/HW
> can write expanded size data after encryption.
