Because vlan_features of a veth interface has the NETIF_F_HW_VLAN_[CTAG/STAG]_TX bits, veth0.10 also has that feature, so dev_hard_start_xmit(veth0.10) doesn't call __vlan_put_tag() and vlan_dev_hard_start_xmit(veth0.10) overwrites vlan_tci. This prevents us from using a combination of 802.1ad and 802.1Q in containers, etc. Signed-off-by: Toshiaki Makita Acked-by: Flavio Leitner Signed-off-by: David S.
