Description

In 2.7/23.01 QinQ uses if_vlan instead of netgraph and set the outer tag ethertype as 802.1ad (0x88a8). That is the expected tags tag type for most QinQ links but is not what netgraph set in 2.6/22.05 and earlier. That used 802.1q (0x8100) for both tags. That could lead to existing QinQ links failing at upgrade.

This change needs to be documented. The new behaviour is probably correct for most new interfaces.

There should be an option to revert to the previous behaviour if required. ifconfig can set the vlanproto value directly in 23.01.

Existing QinQ interfaces could be automatically set to that at upgrade to maintain compatibility with connected devices.

Is there any timeline to resolve this one? Double stacked 802.1q packets are far more common than 802.1ad in my experience. This is also a breaking change from anything pre 2.7.
