following is my setkey configration. I can get SAD and SPD. but when I run " ping6 -I rl0 3ffe:501:ffff:103:20a:ebff:fe85:9e56 " on FreeBSD FreeBSD report: kernel: esp_aesctr_decrypt aes-ctr:payload length must be multiple of 16 kernel: decrypt fail in IPv6 ESP input :

(I cannot comment on this problem.  Looks like a padding bug.)

add 3ffe:501:ffff:103:20a:ebff:fe85:9e56 3ffe:501:ffff:104:21d:fff:fe19:59fc esp 0x1000 -m tunnel -E aes-ctr "ipv6readylogoaes2to1" -A hmac-sha1 "ipv6readylogsha12to1";

Do not use AES-CTR with static keys!  Re-use of keys with a stream
cipher will allow listeners to recover the plaintext.
(See section 7 of RFC 3686.)

but when I use "

ping6 -I rl0 -s 11(or 12,13,14) 3ffe:501:ffff:103:20a:ebff:fe85:9e56"
it is no problem
