Correct. Set it to zero and the flowtable will be bypassed.
flowtable.c:
static uint32_t
ipv6_flow_lookup_hash_internal(
struct sockaddr_in6 *ssin6, struct sockaddr_in6 *dsin6,
uint32_t *key, uint16_t flags)
{
uint16_t sport, dport;
uint8_t proto;
int offset = 0;
if ((V_flowtable_enable == 0) || (V_flowtable_ready == 0))
return (0);
