define KernelPackage/crypto-eip/description
  Enable crypto engine to accelerate encrypt/decrypt. Support look aside
  mode (semi-HW) and inline mode (pure-HW). Look aside mode is bind with
  Linux Crypto API and support AES, DES, SHA1, and SHA2 algorithms. In-
  line mode only support ESP Tunnel mode (single tunnel) now.
