TDA4VM: arp based on vlan not work

Hi TI expert,
I use sdk8.2 QNX+RTOS, TDA4 connect to PC via cpsw9g,RGMII, Now I encount a issue:
I config IP in TDA4 with a vlan 172.16.104.90 and a without vlan 192.168.1.10. In PC I config the responding the same net segment IP :
   

I ping TDA4 from PC with no vlan IP, PASS. But with vlan IP, NG. 
From wireshark, I see that, when ping with no vlan IP, PC can send and get arp info.  But ping with vlan IP, PC just send request arp info, not get respon arp info:




However, If ping PC from TDA4 with vlan IP, it then PASS.



From E2E,  I see a related issue: DRA821U: cpsw5g VLAN configuration - Processors forum - Processors - TI E2E support forums

Could you give some advice or patch to this issue ?

Thanks.
