AXT1800 Unable to Install OpenvSwitch


I use AXT1800, ver 4.2.0 with kernel 4.4. and want to use Open vSwitch. But unable to install openvswitch.
It report kmod-openvswitch unavailable.
I also try the version with kernel 5.4, still have no kmod-openvswitch.
Please help to advise if we can have a version includes kmod-openvswitch.

I tried to compile kmod-openvswitch, but unfortunately there is no relevant code in the source code.
Therefore, I’m sorry that I can’t help you
