Added new procfs flag to toggle the automatic addition of prefix
routes on a per device basis. The new flag is accept_ra_prefix_route.
A value of 0 for the flag maybe used in some forwarding scenarios
when a userspace daemon is managing the routing.
Manual deletion of the kernel installed route was not sufficient as
kernel was adding back the route.
Defaults to 1 as to not break existing behavior.

this seems to duplicate accept_ra_pinfo
Thanks David. We will try out that entry instead and check.
