In order to facilitate the access to the private data, after the crypto operation, two new macros have been implemented:
- rte_crypto_op_ctod_offset(c,t,o), which returns a pointer to "o" bytes after the start of the crypto operation - rte_crypto_op_ctophys_offset(c, o), which returns the physical address of the data "o" bytes after the start of the crypto operation Signed-off-by: Pablo de Lara <pablo.de.lara.gua...@intel.com> --- lib/librte_cryptodev/rte_cryptodev.h | 29 +++++++++++++++++++++++++++++ 1 file changed, 29 insertions(+) diff --git a/lib/librte_cryptodev/rte_cryptodev.h b/lib/librte_cryptodev/rte_cryptodev.h index 88aeb87..bd09176 100644 --- a/lib/librte_cryptodev/rte_cryptodev.h +++ b/lib/librte_cryptodev/rte_cryptodev.h @@ -118,6 +118,35 @@ extern const char **rte_cyptodev_names; #define CDEV_PMD_TRACE(...)
