Currently, I have two physical hosts. When my VYOS (version 1.2.1) is migrated to a network card type Broadcom COrporation, I find that SSH cannot work. When migrating back to another network card type intel® Ethernet Controller, SSH works normally.
When another VYOS version is 1.1.7, SSH works normally on both physical hosts
I configure QinQ mode for any version of VYOS interface。
Is Broadcom Corporation not supporting VYOS 1.2.1 version QinQ mode?

[edit]
@Henry maybe these ports have different sequences? I mean eth0 this is eth1…
If you use QinQ on eth1 too, check please also ethertype
And also you need to increase MTU on both interfaces
