Don't find em28xx-kernel-module

first of all, i am new to lede.
So, sorry if i ask a stupid question!!
I want to use a dvb-c stick at my router.
Therefore i am trying to build a image with dvb support, according to the basic image bulding guide in the
lede documentation.
But i have the problem, that i don't find the "em28xx-kernel-module"
in the configuration menu under kernel modules.
Any suggestion?

There is no such package in the LEDE repositories:[Name_pkg-dependencies*~]=28xx

You are right.
But how can i use a dvb device on my router?
I searched in the internet, but i don't find a description.
