17.1. Features

Nitrox crypto PMD has support for:

Cipher algorithms:

• RTE_CRYPTO_CIPHER_AES_CBC
• RTE_CRYPTO_CIPHER_3DES_CBC

Hash algorithms:

• RTE_CRYPTO_AUTH_SHA1_HMAC
• RTE_CRYPTO_AUTH_SHA224_HMAC
• RTE_CRYPTO_AUTH_SHA256_HMAC

Supported AEAD algorithms:

• RTE_CRYPTO_AEAD_AES_GCM
• RTE_CRYPTO_AEAD_AES_CCM

17.2. Limitations

• Session-less APIs are not supported.

17.3. Initialization

Nitrox crypto PMD depend on Nitrox kernel PF driver being installed on the platform. Nitrox PF driver is required to create VF devices which will be used by the PMD. Each VF device can enable one cryptodev PMD.

Nitrox kernel PF driver is available as part of CNN55XX-Driver SDK. The SDK and it’s installation instructions can be obtained from: Marvell Technical Documentation Portal.
