Subject: ah: update maximum truncated ICV length
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=e44f391187495e0deaf7b9f0077e94f270837d1a;p=linux-beck.git

ah: update maximum truncated ICV length

For SHA256, RFC4868 requires to truncate ICV length to 128 bits,
hence MAX_AH_AUTH_LEN should be updated to 16.
