It looks like a double rename, but it's more than that.
In first patch rte_crypto_op was renamed rte_crypto_sym_op and moved from
rte_crypto.h to to rte_crypto_sym.h
because it was exclusively for symmetric operations.
In the later patch a more generic rte_crypto_op was introduced in rte_crypto.h
which can handle various operation types by having a type and union. Initially
the only type is symmetric and so the union points to an rte_crypto_sym_op but
it's planned to extended to handle asymmetric.

Agreed. We will look at adding the debug needed. However this is not likely to
make it into the patchset today.
