flow_dissector: Add control/reporting of encapsulation
Add an input flag to flow dissector on rather dissection should stop when encapsulation is detected (IP/IP or GRE). Also, add a key_control flag that indicates encapsulation was encountered during the dissection. Signed-off-by: Tom Herbert <tom@herbertland.com> Signed-off-by: David S. Miller <davem@davemloft.net>
