Hello, I have tried to set CONFIG_PACKET=m in kernel 4.11 and rebuilt the kernel and rebooted. I am using Ubuntu 16.04. After reboot, the af_packet.ko kernel module is loaded: lsmod shows: af_packet 45056 2 But I cannot remove it: rmmod af_packet rmmod: ERROR: Module af_packet is in use I want to be able to rmmod it, for adding debug printing, etc. How can I find which applications uses it ? (So I will be able to stop them, rmmod af_packet, and then insmod it again)?
