This would need an update in doc/guides/cryptodevs/features/default.ini as well.

However, it would be better to use the capability thing.
https://patches.dpdk.org/project/dpdk/patch/20241004181255.916-1-gmuthukrishn@marvell.com/

This patch add SM2 op specific capability.
It would be better to add this partial SM2 in the enum rte_crypto_sm2_op_capa defined in the above patch.
