From c92b96553a80c1dbe2ebe128bbe37c8f98f148bf Mon Sep 17 00:00:00 2001 From: Julian Anastasov Date: Mon, 8 Oct 2012 11:41:19 +0000 Subject: ipv4: Add FLOWI_FLAG_KNOWN_NH Add flag to request that output route should be returned with known rt_gateway, in case we want to use it as nexthop for neighbour resolving. The returned route can be cached as follows: - in NH exception: because the cached routes are not shared with other destinations - in FIB NH: when using gateway because all destinations for NH share same gateway As last option, to return rt_gateway!=0 we have to set DST_NOCACHE.
