[PATCH net-next v2 1/2] rndis_host: add Telit LE310X1 RNDIS USB ID

[Shaoxu Liu]

Add a device match entry for Telit Cinterion LE310X1 RNDIS interface
(VID:PID 1bc7:7030).

This is a functional no-op and keeps using the generic rndis_info for now.
Power-management behavior is handled in a follow-up patch.

[PATCH net-next v2 2/2] rndis_host: enable power management for Telit LE310X1

[Shaoxu Liu]

Enable autosuspend support for Telit Cinterion LE310X1 RNDIS interface
by selecting a driver_info variant with manage_power callback.

This keeps power management scoped to the new Telit ID only, and avoids
changing behavior for all existing RNDIS devices.
