From: Akhil Goyal Date: Sat, 9 May 2020 23:12:09 +0000 (+0530) Subject: cryptodev: add feature flag for non-byte aligned data X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=e11bdd37745229bf26b557305c07d118c3dbaad7;p=dpdk.git cryptodev: add feature flag for non-byte aligned data Some wireless algos like SNOW, ZUC may support input data in bits which are not byte aligned. However, not all PMDs can support this requirement. Hence added a new feature flag RTE_CRYPTODEV_FF_NON_BYTE_ALIGNED_DATA to identify which all PMDs can support non-byte aligned data.
