ipv6: Use ipv6_authlen for len in ipv6_skip_exthdr
In ipv6_skip_exthdr, the lengh of AH header is computed manually as (hp->hdrlen+2)<<2. However, in include/linux/ipv6.h, a macro named ipv6_authlen is already defined for exactly the same job. This commit replaces the manual computation code with the macro. Signed-off-by: Xiang Gao <qasdfgtyuiop@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
