Bug#986619: linux-image-5.10.0-5-amd64: bonding broken on 5.10.0-5 (5.10.26)

[Francesc Ferrer]

I can confirm this behaviour. I also have wired and wireless bonded, and 
it stopped working on 5.10.0-5. Everything looks fine: bond, gateway, 
DNS, ... all have correct if addresses obtained from dhcp; resolvectl 
looks fine; but I cannot even ping my gateway/router.
