loopback network interface driver location

Is loopback network interface driver statically compiled in kernel or dynamically pluggable/un-pluggable?where is it located in linux directory structure?

Is this any use?

Code:

~$ locate loopback
................
/lib/modules/3.0-3.dmz.1-liquorix-amd64/kernel/drivers/media/rc/rc-loopback.ko
/lib/modules/3.0-3.dmz.1-liquorix-amd64/kernel/drivers/target/loopback
/lib/modules/3.0-3.dmz.1-liquorix-amd64/kernel/drivers/target/loopback/tcm_loop.ko
...............
/usr/src/linux-headers-3.0-3.dmz.1-liquorix-amd64/drivers/target/loopback
/usr/src/linux-headers-3.0-3.dmz.1-liquorix-amd64/drivers/target/loopback/Kconfig
/usr/src/linux-headers-3.0-3.dmz.1-liquorix-amd64/drivers/target/loopback/Makefile

not of much help.thanks anyways.

All i want to do is to remove(rmmod) the default pseudo loopback network interface driver and plug(insmod) my own customized pseudo loopback network interface driver.Any help?

Hello avee137,

why do you think that jdkaye's post is not helpful? what do you expect?

Most likely if you can't find the module on your system it is not compiled as a module but built directly into the kernel. Or it isn't a module at all (cannot be compiled as a module), I don't know.

It's up to you to find the code for the network-loopback-driver...... well, on my System it's in /usr/src/linux-3.0-rc1/drivers/net/loopback.c, and recompile the kernel with your own code.

Thanks for your pointer markush.

I too eventually concluded that its not compiled as module. it is statically compiled in kernel, it seems. i ll try to recompile the kernel.

I read that it would be here drivers/net/loopback.c
