e1000 only hardware pads to 64 bytes, but if you use the vlan module and turn off the hardware assistance of inserting tags, by unsetting NETIF_F_HW_VLAN_* in netdev->features. the software insertion sounds like it should work for you at the cost of higher CPU. >>> I'd like to change it so it first pads the frame to 64 B and >>> appends the VLAN tag afterwards, so the resulting VLAN frame would >>> be 68 bytes minimum. at least for e1000 this isn't possible in the driver, while still doing hardware vlan insertion.
