canutils 使用
```
./cansend can0 -e 0x11 0x22 0x33 0x44 0x55 0x66 0x77 0x88
```
发送默认ID为0x1的can标准帧，数据为0x11 22 33 44 55 66 77 88, 每次最大8个byte
```
./cansend can0 -i 0x800 0x11 0x22 0x33 0x44 0x55 0x66 0x77 0x88 -e
```
-e 表示扩展帧，CAN_ID最大29bit，标准帧CAN_ID最大11bit
-i表示CAN_ID

iproute2 使用

ip link set llcecan0 type can restart-ms 100
ip link set llcecan0 up type can bitrate 1000000
ip link set llcecan0 up type can
ip -details link show llcecan0ip link set llcecan1 type can restart-ms 100
ip link set llcecan1 up type can bitrate 1000000
ip link set llcecan1 up type can
ip -details link show llcecan1
candump llcecan1 &
cansend llcecan0 123#11223344556677
