Issue or Suggestion Description

dev_change_proto_down_generi() is undefined, how to replace it?

[tswen]

The primary purpose of the dev_change_proto_down_generic API is to control the down or up state of a network interface. You can check if there is a similar API in the 3.18.x kernel version that can handle the corresponding operations.
