udhcpc和udhcpd移植到arm平台

平台介紹：

主機端—Ubuntu 11.04

開發板內核—linux-2.6.30

Busybox版本—1.6.0

BusyBox各版本下載 http://www.linuxidc.com/Linux/2011-08/40704.htm

移植過程：

內核移植：make menuconfig

選擇上Networking --->
Networking support
Networking options --->

<*> Packet socket

[*] Packet socket: mmapped IO

[*] IP: DHCP support

[*] IP: BOOTP support

[*] IP: RARP support

[ * ] Network packet filtering (replaces ipchains) ---> //添加，後面子選項可不選，配置CONFIG_NETFILTER

說明：若沒選 Packet socket, [ * ] Network packet filtering (replaces ipchains) --->選項，在執行udhcpc命令時出現如下錯誤：

Networking Utilities --->
udhcp Server/Client --->

[*] udhcp Server (udhcpd)

[*] dhcprelay

[*] Lease display utility (dumpleases)

[*] udhcp Client (udhcpc)

[*] Log udhcp messages to syslog

重新編譯內核和busybox，得到udhcpc和udhcpd命令。
