No idea, I think the passthru mode prevents direct access to netdev-bond0, but I don't know what is done internally that can causes this.
To illustrate :
- ping gateway => OK
- create my device with : ip link add link netdev-bond0 name netdev-specific type macvlan mode passthru
- ping gateway => no response
- ping my host from outside => no response
- remove my device with : ip link del netdev-specific type macvlan
- ping gateway => OK
I checked ifconfig and route -n, but results are the same before and after creating my device.
If I move my IP configuration from netdev-bond0 to netdev-specific, it works (ping & IP protocols).
