Comment # 17 on bug 1019412 from Michal Kube��ek

(In reply to Jason Mader from comment #16)
> Doesn't work for me. Incompatible with hmac-sha2-384 on FreeBSD 11.1.

If you believe FreeBSD implementation is correct and Linux implementation is
wrong, please provide a capture showing an outgoing IPv6/AH packet incorrect
in the sense of RFC 4302 and its errata or a correct incoming packet that is
not processed correctly by linux kernel.

As far as I can say, the padding in IPv6/AH headers is done exactly the way
RFC 4302 describes.
