From def499c929a72ba11b25e26e26e900ba3d5c2762 Mon Sep 17 00:00:00 2001 From: Roopa Prabhu Date: Mon, 27 Mar 2017 15:46:41 -0700 Subject: [PATCH] vxlan: don't age NTF_EXT_LEARNED fdb entries vxlan driver already implicitly supports installing of external fdb entries with NTF_EXT_LEARNED. This patch just makes sure these entries are not aged by the vxlan driver. An external entity managing these entries will age them out. This is consistent with the use of NTF_EXT_LEARNED in the bridge driver. Signed-off-by: Roopa Prabhu Signed-off-by: David S.
