hi
now i develop router using openwrt.
my router model is Linksys WRT1900AC(ver1)
until now. i have done make firmware image file for my target router using openwrt build system.

my goal is making custom packet management algorithm.
so i think that i should modify kernel source and build this modified kernel source.

at this point. i have question.
my plan is as follows.

1. Modify kernel source code in build_dir(eg.build_dir/target-*/linux-mvebu/linux-4.4.14/net/sched/fq_codel.c)
2. make menuconfig && make

if i doing so, is it possible to get custom firmware image file(custom firmware means that it include modified kernel source) ????
