The vxcan can be used for cross namespace communication. + + In opposite to vcan loopback devices the vxcan only forwards CAN + frames to its pair and does *not* provide a local echo of sent + CAN frames. To disable a potential echo in af_can.c the vxcan driver + announces IFF_ECHO in the interface flags.
