From 1f84eab4ad73bcb7d779cba65291fe62909e373f Mon Sep 17 00:00:00 2001 From: =?utf8?q?Bj=C3=B8rn=20Mork?= Date: Wed, 27 Feb 2013 03:08:58 +0000 Subject: [PATCH] net: cdc_ncm: tag Huawei devices (e.g. E5331) with FLAG_WWAN MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Tag all Huawei NCM devices as WWAN modems, as we don't know of any which are not. This is necessary for userspace clients to know that the device requires further setup on e.g. an AT-capable serial ports before connectivity is available.
