Hi,

Is it possible to backport the commit "net: switchdev: do not propagate bridge updates across bridges" [1] to linux-5.4?

This patch fixes faulty hardware configuration when nesting DSA-offloaded bridges into software bridges, which can cause vlan_filtering to be disabled in hardware, even though it should be enabled. Therefore, ports/vlans get connected, even though they should be isolated.

A backport of this patch for linux-5.4 has recently been accepted in OpenWrt [2]

Best regards,
Fabian Bläse
