net: ipv6 eliminate parameter "int addrlen" in function fib6_add_1
The "int addrlen" in fib6_add_1 is rebundant, as we can get it from parameter "struct in6_addr *addr" once we modified its type. And also fix some coding style issues in fib6_add_1 Signed-off-by: Fan Du <fan.du@windriver.com> Acked-by: Hannes Frederic Sowa <hannes@stressinduktion.org> Signed-off-by: David S.
