From 6ca219e7de9fb54b4eac9c3f14a0cdf2b39d723d Mon Sep 17 00:00:00 2001 From: Jiri Pirko Date: Thu, 28 Feb 2019 06:59:17 +0000 Subject: [PATCH] mlxsw: spectrum_acl: Don't migrate already migrated entry Check if the entry is already in a chunk where we want it to be. In that case, skip migration. This is preparation for "per parts" migration where this situation may occur. Signed-off-by: Jiri Pirko Signed-off-by: Ido Schimmel Signed-off-by: David S.
