Ticket Name: TDA2SX: automatically inserts VLAN tags when sending Ethernet packets

Query Text:
Part Number: TDA2SX Hi TI experts, we use custom board with TDA2x and sending multicast packets, but we can't recieve it. After capturing packets through wireshark we discovered VLAN tags in packets header. We didn't enable VLAN Tagging at code or any configuration file. What's way to disable VLAN tags from Ethernet packets? Some additional information: 1) Device: TDA2x custom board 2) Operation system: TI RTOS 3) SDK version: PROCESSOR_SDK_RADAR_03_07_00_00 4) Ethernet interface: Configured at Eth0

Responses:
I just add a some new information. When we change destination IP from 239.168.1.50 to 192.168.1.100 VLAN Tagging is gone. I can't understand why is multicast IP add VLAN tag?
