dpdk-cryptodev: improve cryptodev cache ring implementation
Sw ring is renamed to the cache ring. This name better reflects the puropse of this ring. We've introduced push/pop functions, as well as other utility functions which remove code repetition. Error handlig is improved: previously in case of an error all frame elements were marked as bad, now only these for which errors occured have the error status set. Unnecessary stats counters have been removed. Type: improvement Signed-off-by: Piotr Bronowski <piotrx.bronowski@intel.com> Change-Id: I2fd42a529ac84ce5ad260611d6b35a861d441c79
