From 7488be701029a86259dcd297a3c665eb65bdac6e Mon Sep 17 00:00:00 2001 From: Koen Vandeputte Date: Mon, 27 Nov 2017 18:31:30 +0100 Subject: [PATCH] uqmi: fix raw-ip mode for newer lte modems Some newer LTE modems, like the MC7455 or EC25-E do not support "802.3" mode, and will stay in "raw-ip" regardless of the mode being set. In this case, the driver must be informed that it should handle all packets in raw mode. [1] This commit fixes connectivity issues for these devices.
