Date: Mon, 17 Jan 2011 22:46:00 -0800 From: Jesse Gross <jesse@...ira.com> To: David Miller <davem@...emloft.net> Cc: Eric Dumazet <eric.dumazet@...il.com>, netdev@...r.kernel.org 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.
