> Subject: [PATCH] revert async probing of VMBus network devices.
>
> Doing asynchronous probing can lead to reordered network device names.
> And because udev doesn't have any useful information to construct a
> persistent name, this causes VM's to sporadically boot with reordered device
> names and no connectivity.
>
> This shows up on the Ubuntu image on larger VM's where 30% of the time
> eth0 and eth1 get swapped.
>
> Note: udev MAC address policy is disabled on Azure images because the
> netvsc and PCI VF will have the same mac address.
>
> Fixes: af0a5646cb8d ("use the new async probing feature for the hyperv
> drivers")
