HI,
   I found that internal port and netdev port can not ping each other, can you tell me why?
  The topology is like this:
 p0: type=internal, tag=100, vlan_mode=access, ip=192.168.1.100/24, br0, namespace ns0
 eth0: type=netndev, tag=100, vlan_mode=access, ip=192.168.1.1/24, br0


  then from netns ns0 port p0 ping 192.168.1.1, I can see that eth0 received the arp packet with tcpdump,  but no arp reply from eth0
 but if I add port p2 (internal access port, tag=100, ip=192.168.1.2/24), then down/up eth0
 after the above step, we can ping from p0 to eth0.
