Date: Sat, 27 Apr 2019 19:27:29 -0700 From: David Ahern <dsahern@...nel.org> To: davem@...emloft.net, netdev@...r.kernel.org Cc: idosch@...lanox.com, David Ahern <dsahern@...il.com> Subject: [PATCH v2 net-next 2/7] ipv4: Pass fib_nh_common to rt_cache_route From: David Ahern <dsahern@...il.com> Now that the cached routes are in fib_nh_common, pass it to rt_cache_route and simplify its callers. For rt_set_nexthop, the tclassid becomes the last user of fib_nh so move the container of under the #ifdef CONFIG_IP_ROUTE_CLASSID.
