Subject: [PATCH net-next 02/14] mlxsw: spectrum_acl: Don't migrate already migrated entry
Date: Thu, 28 Feb 2019 06:59:17 +0000	[thread overview]
Message-ID: <20190228065850.7471-3-idosch@mellanox.com> (raw)
In-Reply-To: <20190228065850.7471-1-idosch@mellanox.com>

From: Jiri Pirko <jiri@mellanox.com>

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.
