I am trying to install PF_Ring on my Ubuntu 22.04. I downloaded the sources and followed steps in read me file. All steps are successful went successful but when I try to test PF_Ring with following command, I am getting error.

# sudo su
# insmod ./kernel/pf_ring.ko

insmod: ERROR: could not load module ./kernel/pf_ring.ko: No such file or directory

But #ls -a shows that there is a file with name pf_ring.ko in current directory.

Can someone guide me how to fix that.
