Hi Andrew,
Would you please give more explanation about the problem that
the patch wants to fix?
Let's consider if tunnel is IPIP (0x3ULL << 45) or MPLSINUDP (0x5ULL << 45).
If so flags & VXLAN (0x1ULL << 45), still makes (0x1ULL << 45)==VXLAN,
but it is not a VXLAN tunnel packet.
Andrew.
Thanks,
Jiayu
