Description
In vlan_test cases 1, I found my environment NIC can receive the desired VLAN tagged packets, ex: 100.
But when I using tcpdump in PTF docker interface, ex: eth1, I can't capture any packets.
I make sure the PTF docker have created the desired VLAN interface, ex: eth1.100, by "ifconfig -a -s" when doing the test.
The vlan test case 1 for VLAN untagged packet is passed, but for checking VLAN tagged packet is fail.
Could you teach me how to debug it? For checking packets loss in physical NIC to PTF docker interface.
