执行过程中会报找不到switch-config命令的错误
在网上查了很久，顺藤摸瓜找到了
ALE和CPSW相关
搜到了CPSW的一个介绍TI网站的：http://processors.wiki.ti.com/index.php/Linux_Core_CPSW_User%27s_Guide#Introduction
TI Common Platform Ethernet Switch (CPSW) is a three port switch (one CPU port and two external ports). The CPSW or Ethernet Switch driver follows the standard Linux network interface architecture.
The driver supports the following features:
- 10/100/1000 Mbps mode of operation.
- Auto negotiation.
- Linux NAPI support
- Switch Support
- VLAN (Subscription common for all ports)
- Ethertool (Supports only Slave 0 decided in cpsw DT node)
- Dual Standalone EMAC mode
Dual Standalone EMAC mode
ALE：address lookup engine 地址查询引擎，是TI创造的一种对于双网卡选择的方式：
TI对于网卡设备的通用管理是CPSW方式，分为host和slave

psoc:
# ethtool -i eth0
driver: st_gmac
如果有cpsw
# ethtool -i eth0
driver: cpsw
