From dcb1ecb50edf8219c3bd851de35897fb024c423b Mon Sep 17 00:00:00 2001 From: David Ahern Date: Mon, 3 Jun 2019 20:19:50 -0700 Subject: ipv4: Prepare for fib6_nh from a nexthop object Convert more IPv4 code to use fib_nh_common over fib_nh to enable routes to use a fib6_nh based nexthop. In the end, only code not using a nexthop object in a fib_info should directly access fib_nh in a fib_info without checking the famiy and going through fib_nh_common. Those functions will be marked when it is not directly evident. Signed-off-by: David Ahern Signed-off-by: David S.
