From 623716dd4318cd05022d5d1bb0875906ddfc12c2 Mon Sep 17 00:00:00 2001 From: John Crispin Date: Wed, 28 Jan 2015 19:19:33 +0000 Subject: [PATCH] comgt-ncm: Fix NCM protocol This patch fixes the NCM protocol by adding the missing ifname to the netifd script and changing one unintended "send" statement to "print" in runcommand.gcom. It also cleans up logging and makes the manufacturer names case-insensitive. Furthermore, comgt-ncm should not depend on the USB-serial-related kernel modules, as the cdc-wdm control device works without them. There is also no need to depend on kmod-huawei-cdc-ncm, since other manufacturers (like Sony-Ericsson and Samsung) which use other kernel modules should also be supported. I'd appreciate if someone with Samsung or Sony-Ericsson modems could test this, I was only able to test it with Huawei E3276, E3372 and E353.
