If the other host is also +Linux you should load ``thunderbolt-net`` manually on one host (it does +not matter which one):: + + # modprobe thunderbolt-net + +This triggers module load on the other host automatically. If the driver +is built-in to the kernel image, there is no need to do anything. + +The driver will create one virtual ethernet interface per Thunderbolt +port which are named like ``thunderbolt0`` and so on. From this point +you can either use standard userspace tools like ``ifconfig`` to +configure the interface or let your GUI to handle it automatically. |
