Hi,
Recently this patch
https://github.com/DPDK/dpdk/commit/5284adad3e95025f9901869f581c8c04ea642d32
made the following change:
* mbuf: Removed the unioned fields ``userdata`` and ``udata64``
from the structure ``rte_mbuf``. It is replaced with dynamic fields.
Which breaks the SPDK project’s crypto and compression capabilities as we use
userdata to store context for our operation so it can be retrieved upcon
completion of the operation. It’s not clear to me that we are safe to use the
fields that were added:
uint64_t dynfield1[2]; /**< Reserved for dynamic fields. */
uint64_t dynfield1[3]; /**< Reserved for dynamic fields. */
based on the comments. Can someone please advise, why was this done and can we
use these fields?
Thanks,
Paul
