Network drivers such as igb or igc call eth_get_headlen() to determine the header length for their to be constructed skbs in receive path. When running HSR on top of these drivers, it results in triggering BUG_ON() in skb_pull(). The reason is the skb headlen is not sufficient for HSR to work correctly. skb_pull() notices that. For instance, eth_get_headlen() returns 14 bytes for TCP traffic over HSR which is not correct. The problem is, the flow dissection code does not take HSR into account. Therefore, add support for it.
