Review: I am using it to control robotics motors. One caveat is that NetworkManager cannot configure CAN interfaces so you have to use systemd-networkd. The two do not always play nicely so you may have to uninstall NetworkManager. systemd-networkd is useful if you want to make configurations persistent, for example setting the buffer size. Otherwise you have to run the configuration commands on every boot.
Review: Easy to integrate and use.
