The series adds an ability for the bridge to function in non-promiscuous mode.
What is the practical applications for such setup? In other words,
in which cases I would want to put bridge into non-promiscuous
mode and specify some uplink ports?
On of the applications would be when bridge is an edge device servicing
a VM deployment. Each of the VMs knows the mac address that the guest
has and may program that mac onto the uplinks.
Why wouldn't that environment just use macvlan?
Is it because changing libvirt is harder than changing the kernel?
No, because macvlan has a drawback that it doesn't easily let guests
talk to the host. Bridge is still most commonly used for just that reason.
