选择上Networking --->

[*] IP: DHCP support

[*] IP: BOOTP support

[*] IP: RARP support

[ * ] Network packet filtering (replaces ipchains) ---> //添加，后面子选项可不选，配置CONFIG_NETFILTER

说明：若没选 Packet socket, [ * ] Network packet filtering (replaces ipchains) --->选项，在执行udhcpc命令时出现如下错误：

重新编译内核和busybox，得到udhcpc和udhcpd命令。
