From f9d7a1187dfefc6b54b53e0ffff4d26c0eff2702 Mon Sep 17 00:00:00 2001 From: Shan Wei Date: Tue, 5 Jul 2011 20:44:17 -0700 Subject: [PATCH] net: Add GSO to vlan_features initialization Just add GSO to vlan_features initialization, and update comments. When we set offload features, vlan_dev_fix_features() will do more check. In vlan_dev_fix_features(), final features is decided by features of real device and vlan_features of real device.
