[OpenWrt-Devel] [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.
