Public bug reported:

Due to the lack of HW accelerated AES, ChaCha20 is currently the most
efficient cypher for Raspberry Pi4 users. It is enabled in the current
5.4 ubuntu kernels but unfortunately without
CONFIG_CRYPTO_NHPOLY1305_NEON

CONFIG_CRYPTO_CHACHA20_NEON=m
# CONFIG_CRYPTO_NHPOLY1305_NEON is not set

The performance is significantly reduced as indicated in
