Add virtio CAN driver based on Virtio 1.4 specification (see https://github.com/oasis-tcs/virtio-spec/tree/virtio-1.4). The driver implements a complete CAN bus interface over Virtio transport, supporting both CAN Classic and CAN-FD Ids. In term of frames, it supports classic and CAN FD. RTR frames are only supported with classic CAN. Usage: - "ip link set up can0" - start controller - "ip link set down can0" - stop controller - "candump can0" - receive frames - "cansend can0 123#DEADBEEF" - send frames Signed-off-by: Harald Mommer <harald.mommer@oss.qualcomm.com> Co-developed-by: Harald Mommer <harald.mommer@oss.qualcomm.com> Signed-off-by: Mikhail Golubev-Ciuchea <mikhail.golubev-ciuchea@oss.qualcomm.com> Co-developed-by: Marc Kleine-Budde <mkl@pengutronix.de> Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de> Cc: Damir Shaikhutdinov <Damir.Shaikhutdinov@opensynergy.com> Reviewed-by: Francesco Valla <francesco@valla.it> Tested-by: Francesco Valla <francesco@valla.it> Signed-off-by: Matias Ezequiel Vara Larsen <mvaralar@redhat.com> Signed-off-by: Michael S.
