From f94898ea6682977f15c5a8f9ffb293a14f95455a Mon Sep 17 00:00:00 2001 From: Dan Williams Date: Tue, 24 Jul 2012 08:43:22 +0000 Subject: cdc-ncm: tag Ericsson WWAN devices (eg F5521gw) with FLAG_WWAN Tag Ericsson NCM devices as WWAN modems, since they almost certainly all are. This way userspace clients know that the device requires further setup on the AT-capable serial ports before connectivity is available.
