From: Gal Pressman The hardware supports segmentation offload of UDP over GRE over vlan packets, allow it by adding NETIF_F_GSO_UDP_L4 to hw_enc_features which will make the vlan device inherit it to its own hw_enc_features. Side note: it is quite confusing that this change wasn't needed to offload encapsulated UDP packets regardless of vlan, but that's the way that the stack handles gso partial features, it assumes they're supported without caring if the feature is supported in hw_enc_features.
