flow_dissector: Add support for HSR
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.
