This device claims TSO and checksum support for vlans. It also allows a user to control vlan acceleration offloading. As such, it is possible to turn off vlan acceleration and configure a vlan which will continue to support TSO and hw checksums. In such situation the packet passed down the the device will contain a vlan header and skb->protocol will be set to ETH_P_8021Q. The device assumes that skb->protocol contains network protocol value and uses that value to set up TSO and checksum information. This results in corrupted frames sent on the wire. This patch extract the protocol value correctly and corrects TSO and checksums for non-accelerated traffic. Fix this by using vlan_get_protocol() helper.
