From 0c4b2d370514cb4f3454dd3b18f031d2651fab73 Mon Sep 17 00:00:00 2001 From: Michał Mirosław Date: Sat, 10 Nov 2018 19:58:36 +0100 Subject: net: remove VLAN_TAG_PRESENT MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Replace VLAN_TAG_PRESENT with single bit flag and free up VLAN.CFI overload. Now VLAN.CFI is visible in networking stack and can be passed around intact. Signed-off-by: Michał Mirosław Signed-off-by: David S.
