Message-Id: <20180418223906.16650-2-dsahern@gmail.com>

Subject: [PATCH net-next 1/8] net/ipv6: Rename fib6_info struct elements
Change the prefix for fib6_info struct elements from rt6i_ to fib6_.
rt6i_pcpu and rt6i_exception_bucket are left as is given that they
point to rt6_info entries.
Rename only; not functional change intended.
