[ovs-discuss] about ARP packet for Openflow switch

Hi all,
I have a question about the ARP packet.
Machine configuration as follows:
PC1 192.168.1.18 run ryu controller and openvswitch (version = 2.5.90,
openflow protocols = 1.3)
PC2 192.168.1.17 run a ArpProxy
PC1 has a Daemon, is responsible for sending Arp request to PC2
openflow switch all packets are sent to the default controller

The problem is that PC1 send arprequest (SrcMac = PC1, DstMac = PC2) and
PC2 send arpreply (SrcMac = PC2, DstMac) will not be forwarded to the
controller openflow switch
If PC1 send fake arpreply (ScrMac = PC1, DstMac = PC2) but it will be
forwarded
It is not a problem or openvswitch I set some small steps?

Thanks.
