ipv6: Add "offload" and "trap" indications to routes
In a similar fashion to previous patch, add "offload" and "trap"
indication to IPv6 routes.
This is done by using two unused bits in 'struct fib6_info' to hold
these indications. Capable drivers are expected to set these when
processing the various in-kernel route notifications.
