Kernel Compiling error

Hi,
I am trying to enable “tc” features to the kernel by adding CONFIG_SCH_NETEM and CONFIG_NET_SCH_TBF modules.
I am following the below document.
https://docs.nvidia.com/jetson/l4t/index.html#page/Tegra%20Linux%20Driver%20Package%20Development%20Guide/kernel_custom.html#wwpID0E0LD0HA

First I ran

make ARCH=arm64 O=$TEGRA_KERNEL_OUT tegra_defconfig

I changed CONFIG_SCH_NETEM=m and CONFIG_NET_SCH_TBF=m in the <TEGRA_KERNEL_OUT>/.config . And ran

make ARCH=arm64 O=$TEGRA_KERNEL_OUT -j4

I got the following error.
