For some unknown reason both:
[suppress_type]
type_kind = enum
changed_enumerators = RTE_CRYPTO_ASYM_XFORM_ECPM,
RTE_CRYPTO_ASYM_XFORM_TYPE_LIST_END
and
[suppress_type]
name = rte_crypto_asym_xform_type
works fine for me with check-abi tool:
{DPDK_NEW}/devtools/check-abi.sh ${DPDK_REF}/build/ref ${DPDK_NEW}/build/new
Otherwise I get:
1 function with some indirect sub-type change:
[C]'function void rte_cryptodev_info_get(uint8_t, rte_cryptodev_info*)' at
rte_cryptodev.c:1582:1 has some indirect sub-type changes:
parameter 2 of type 'rte_cryptodev_info*' has sub-type changes:
abidiff: 1.2.0 version
@Akhil - additionally RTE_CRYPTO_ASYM_XFORM_ECDH was supposed to be placed at
the end of the enum. My mistake, I have placed it incorrectly.
Would a fix that swaps these enums be accepted? This could potentially remove
changed_enumerators = RTE_CRYPTO_ASYM_XFORM_ECPM.
