I also suspect that general users may benefit from this aesni patch since
many older wifi chipsets don't support wpa3 in hardware and wpa3 is the new
hotness in wifi.

Herbert, thanks for working on this. If I apply the patches you posted,
that is expected to provide wifi aes decryption speedup similar to what
the original patch I sent does? Or, are additional
needed?
