需要在TDA2x中，实现GateWay IP配置，查看了资料，在如下代码修改：
/*
* Add the default gateway. Since it is the default, the
* destination address and mask are both zero (we go ahead
* and show the assignment for clarity).
*/
bzero(&RT, sizeof(RT));
RT.IPDestAddr = 0;
RT.IPDestMask = 0;
RT.IPGateAddr = inet_addr(GatewayIP);
CfgAddEntry(hCfg, CFGTAG_ROUTE, 0, 0,
sizeof(CI_ROUTE), (UINT8 *)&RT, 0)
上述修改GateWayIP的值是可以正确的修改GateWay IP吗？还需要修改其他的地方吗？
