Is it a Bug? DPAA_SEC-test_cryptodev : output packet length is wrong !

[coolwilled]

Hi,
I run command "cryptodev_dpaa_sec_autotest" in app/test/test_cryptodev.c in
DPDK v25.11. The output mbuf->pkt_len is wrong in the case :
TEST_PDCP_COUNT(uplane_encap_with_integrity(18, UPLINK, SNOW_ENC,
AES_AUTH));
from test_PDCP_PROTO_uplane_encap_all()
from test_PDCP_PROTO_all().
In this case,  in test_pdcp_proto(), the output
ut_params->ibuf->data_len/pkt_len = 73.
The pkt_len is wrong, it should be 71.

Thanks a lot !
