Subject: [dpdk-dev] [PATCH] doc: plan splitting the ethdev ops struct
Date: Mon, 17 Feb 2020 15:38:05 +0000
Message-ID: <20200217153805.888130-1-ferruh.yigit@intel.com> (raw)

For the ABI compatibility it is better to hide internal data structures
from the application as much as possible. But because of some inline
functions 'struct eth_dev_ops' can't be hidden completely.

Plan is to split the 'struct eth_dev_ops' into two as ones used by
inline functions and ones not used, and hide the second part that not
used by inline functions completely to the application.

+* ethdev: Split the ``struct eth_dev_ops`` struct to hide it as much as possible.
+  Currently the ``struct eth_dev_ops`` struct is accessible by the application
+  because some inline functions, like ``rte_eth_tx_descriptor_status()``,
+  access the struct directly. The struct will be separate in two, the ops used
+  by inline functions still will be accessible to user but rest will be hidden.

 * cryptodev: support for using IV with all sizes is added, J0 still can
   be used but only when IV length in following structs ``rte_crypto_auth_xform``,
   ``rte_crypto_aead_xform`` is set to zero. When IV length is greater or equal
