Hi,
I have a  couple of questions related to flowid for IPv6. Please clarify.

1. Why is the below code (ip_output) absent for ip6_output? This is causing
the ipv6 traffic to always flow in just one queue.

if (inp != NULL) {
                INP_LOCK_ASSERT(inp);
                M_SETFIB(m, inp->inp_inc.inc_fibnum);
                if (inp->inp_flags & (INP_HW_FLOWID|INP_SW_FLOWID)) {
                        m->m_pkthdr.flowid = inp->inp_flowid;
                        m->m_flags |= M_FLOWID;
                }
        }
2. Why "fle" is NULL after enabling FLOWTABLE for IPv6

net/flowtable.c
        if (af == AF_INET6)
        {
                fle = flowtable_lookup_mbuf6(ft, m);
                if (fle != NULL && m != NULL && (m->m_flags & M_FLOWID) ==
0) {
                        m->m_flags |= M_FLOWID;
                        m->m_pkthdr.flowid = fle->f_fhash;
                }
        }
