Welcome
He wants to build the image of the Gargoyle is based on OpenWRT r37768. But I need to patch the drivers option.ci cdc_ncm.c to work with the modem Huawei E3276. Cdc_ncm.c driver patch that was visible on the modem WWAN interface. Unfortunately, I do not know how to do or where to find a good patch for these two files?
To patch was applied to the driver when compiling where should you put it?
Throw to / target/linux/generic/patches-3.3
just do not know what the numbers given in the catalog for file names patch
Kernel 3.3.8 is my gargoyle
Below we wanted to add patches but I do not know if they are good?

};I have a package ipk where drivers are improved(patched for E3276) but Is it possible to decompile the package to extract the files and option.c cdc_ncm.c?
