*******************************************多网卡使用说明*******************************************
|
||
*
|
||
* 1.需要配置：
|
||
* a)使能LwIP.c文件中的宏，HAVE_LTE_NETIF;
|
||
* b)使能LWIP配置文件(lwipopts_sfc.h/lwipopts.h)中的宏，LWIP_HOOK_IP4_ROUTE_SRC;
|
||
*
|
||
* 2.IP层根据目标IP地址在网卡列表中选择一个网卡。匹配条件：目标IP地址与网卡在同一个
|
||
* 网段内，即匹配;否则将使用默认网卡;
|
||
*
|
||
* 3.可通过 lwip_set_default_netif函数切换默认网卡。
