From afba9dc1f3a5390475006061c0bdc5ad4915878e Mon Sep 17 00:00:00 2001 From: Stephan Gerhold Date: Wed, 6 Jan 2021 11:07:55 +0100 Subject: net: ipa: modem: add missing SET_NETDEV_DEV() for proper sysfs links At the moment it is quite hard to identify the network interface provided by IPA in userspace components: The network interface is created as virtual device, without any link to the IPA device. The interface name ("rmnet_ipa%d") is the only indication that the network interface belongs to IPA, but this is not very reliable. Add SET_NETDEV_DEV() to associate the network interface with the IPA parent device. This allows userspace services like ModemManager to properly identify that this network interface is provided by IPA and belongs to the modem.
