Enable Virtual CAN Interface (vcan)

I would like to create a virtual CAN interface in Fedora 35. However, Fedora seems to be built without vcan support:

> sudo ip link add dev vcan0 type vcan
Error: unknown device type.

The kernel itself seems to be compiled with the vcan option enabled, but the module seems to be missing (as far as I can tell):

> sudo modprobe vcan
modprobe: FATAL: Module vcan not found in directory /lib/modules/5.15.6-200.fc35.x86_64

> grep CONFIG_CAN_V /boot/config-`uname -r`
CONFIG_CAN_VCAN=m
CONFIG_CAN_VXCAN=m

> dnf search vcan
Last metadata expiration check: 2 days, 3:00:03 ago on Mon 13 Dec 2021 02:23:32 PM CET.
No matches found.

Is there any way for me to provide the missing module?

install

kernel-modules-extra

I’ve done that before, but forgot to reboot. After installing the package and rebooting (duh…) everything works as expected.

Thanks!
