After talking with Bruce about some Intel test results earlier, I've got a solid idea of what the expected behaviors are in five of these, but I'm unsure about the other three. If anyone is able to provide some insight as to what they believe these expected behaviors should be, please let me know as it would be immensely helpful. Thanks! Vlan Strip ON and QinQ Strip OFF: 1. Single VLAN: Expected result: VLAN Stripped 2. Double VLAN: Expected result: Should strip outer VLAN 3. Single 0x88a8 tag only: Expected result: 0x88a8 tag stripped 4. Single VLAN + 1 0x88a8 tag: Expected result: 0x88a8 tag stripped, inner VLAN untouched Vlan Strip ON and QinQ Strip ON: 1. Single VLAN: Expected result: VLAN stripped 2.
