Subject: Re: [RFC PATCH] doc: clarify VLAN and QinQ stripping behaviour
Date: Wed, 16 Jul 2025 15:24:55 -0400	[thread overview]

I've created a list of test cases which I'm planning on implementing
in future QinQ testing. 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. Double VLAN:
    Expected result: Unknown (Outer VLAN stripped?)
3. Single 0x88a8 tag only:
    Expected result: Unknown (0x88a8 tag stripped?)
4. Single VLAN + 1 0x88a8 tag:
    Expected result: Unknown (0x88a8 tag stripped and VLAN tag stripped?)
