mvneta: Fix TSO and checksum for non-acceleration vlan traffic
This driver doesn't appear to support vlan acceleration at
all. However, it does claim to support TSO and IP checksums
for vlan devices. Thus any configured vlan device would
end up passing down partial checksums or TSO frames.
The driver also uses the value from skb->protocol to
determine TSO and checksum offload information, but assumes
that skb->protocol holds the l3 protocol information.
As a result, vlan traffic with partial checksums or TSO
will fail those checks and TSO will not happen.
Fix this by using vlan_get_protocol() helper.
