From 1550c171935d264f522581fd037db5e64a716bb6 Mon Sep 17 00:00:00 2001 From: David Ahern Date: Fri, 5 Apr 2019 16:30:27 -0700 Subject: ipv4: Prepare rtable for IPv6 gateway To allow the gateway to be either an IPv4 or IPv6 address, remove rt_uses_gateway from rtable and replace with rt_gw_family. If rt_gw_family is set it implies rt_uses_gateway. Rename rt_gateway to rt_gw4 to represent the IPv4 version. Signed-off-by: David Ahern Reviewed-by: Ido Schimmel Signed-off-by: David S.
