********************************************************************/ 一、shell 命令流程：
. netcfg can0 down
. ip link set can0 type can bitrate triple-sampling on(或者：ip link set can0 up type can bitrate )
. ip -details -statistic link show can0
. netcfg can0 up
. ./cansend can0 #
. ip -details -statistic link show can0
. ./canfdtest -vv can0
. ip -details -statistic link show can0 二、运行流程：
root@android:/ # netcfg can0 down
root@android:/ # ip link set can0 type can bitrate triple-sampling on
root@android:/ # ip -details -statistic link show can0
