The current VPP functional tests from crypto/sw_device are based on dpdk Intel specific crypto drivers (aesni_gcm/mb).
https://docs.fd.io/csit/master/doc/tests.vpp.func.crypto.sw_device.html?highlight=eth2p%20ethip4ipsectnlsw%20ip4base%20func

Investigate how this can be extended to use the dpdk armv8 crypto driver.
https://dpdk.org/doc/guides/cryptodevs/armv8.html

This is how the VPP startup.conf is configured by CSIT sw_device tests:
[Command_start_exec] 'cat /etc/vpp/startup.conf'
[Command_outputs] unix
{
cli-listen /run/vpp/cli.sock
gid vpp
nodaemon
full-coredump
log /tmp/vpp.log
}
api-segment
{
gid vpp
}
dpdk
{
vdev cryptodev_aesni_gcm_pmd,socket_id=0
vdev cryptodev_aesni_mb_pmd,socket_id=0
}

The vpp process exits by error because the crypto devices are unknown:
