-r --remove
This option causes modprobe to remove, rather than insert a mod-
ule. If the modules it depends on are also unused, modprobe
will try to remove them, too. Unlike insertion, more than one
module can be specified on the command line (it does not make
sense to specify module parameters when removing modules).
There is usually no reason to remove modules, but some buggy
modules require it. Your kernel may not support removal of mod-
ules.
