同时用会有重定义的类型，怎么解决？
```..\..\components et\sal_socket\include\sal_ipaddr.h(68): error: #101: "IPADDR_TYPE_V4" has already been declared in the current scope
 IPADDR_TYPE_V4 = 0U,
..\..\components et\sal_socket\include\sal_ipaddr.h(70): error: #101: "IPADDR_TYPE_V6" has already been declared in the current scope
 IPADDR_TYPE_V6 = 6U,
..\..\components et\sal_socket\include\sal_ipaddr.h(72): error: #101: "IPADDR_TYPE_ANY" has already been declared in the current scope
 IPADDR_TYPE_ANY = 46U
..\..\components et\sal_socket\include\sal_ipaddr.h(76): error: #101: "ip4_addr" has already been declared in the current scope
 typedef struct ip4_addr
