From da796d2755c0c96074c7e07858ae4e7562b79f61 Mon Sep 17 00:00:00 2001 From: Conor Walsh Date: Fri, 16 Apr 2021 17:19:38 +0000 Subject: [PATCH] examples/l3fwd: move routes to common header To prevent code duplication from the addition of lookup methods the routes specified in lpm should be moved to a common header.
