Added new SW PMD which makes use of the libsso SW library,
which provides wireless algorithms ZUC EEA3 and EIA3
in software.
This PMD supports cipher-only, hash-only and chained operations
("cipher then hash" and "hash then cipher") of the following
algorithms:
- RTE_CRYPTO_SYM_CIPHER_ZUC_EEA3
- RTE_CRYPTO_SYM_AUTH_ZUC_EIA3
The ZUC hash and cipher algorithms, which are enabled
by this crypto PMD are implemented by Intel's libsso software
library.
