REQUEST : Add Canbus support for like can2usb dongles

[pergolafabio]

Hi, this is a request for canbus ,canbus is widely used in car industry, but also in home automations...
There are dongles like https://canable.io/ to talk with the system

But we need to load an extra module loaded in kernel 'socketcan'

https://www.kernel.org/doc/html/latest/networking/can.html
https://en.wikipedia.org/wiki/SocketCAN

so we can make use of:

sudo modprobe can
sudo modprobe can_raw
sudo modprobe slcan

is this possible as a request?

EDIT : or is there a way to add those modules manually? any instruction is appreciated!

You can make an PR again https://github.com/home-assistant/operating-system/blob/dev/buildroot-external/kernel/device-support.config - please test it before you make the PR public.

CONFIG_CAN=m
CONFIG_CAN_RAW=m

ok, but if i make a PR wit these lines, you need to bring it in DEV before i can test it right?

CONFIG_CAN=m
CONFIG_CAN_RAW=m
CONFIG_CAN_VCAN=m
CONFIG_CAN_SLCAN=m
CONFIG_CAN_DEV=m
