From 6ee400aafb60289b78fcde5ebccd8c4973fc53f4 Mon Sep 17 00:00:00 2001 From: Jesse Gross Date: Mon, 17 Jan 2011 20:46:00 +0000 Subject: [PATCH] net offloading: Do not mask out NETIF_F_HW_VLAN_TX for vlan. In netif_skb_features() we return only the features that are valid for vlans if we have a vlan packet. However, we should not mask out NETIF_F_HW_VLAN_TX since it enables transmission of vlan tags and is obviously valid.
