When we use the TDA4VM development board to receive Ethernet packets, we use tcpdump to capture packets to show that the packets have a VLAN tag, but the packets we send do not carry a VLAN tag.We have directly verified this by using wireshark to capture packets. We speculate that it may be that TDA4 automatically inserted a VLAN tag into it when receiving Ethernet packets.Do you have a way to remove this VLAN tag? Don’t let TDA4 add a vlan tag when receiving packets.
