Title: make compatible for RT-Thread

simply for copy and delete upgrade method. This folder can't coexist with the current lwip folder, you should delete it.

If you want to use ipv6, you may define
#define RT_LWIP_IPV6
#define RT_LWIP_IPV6_AUTOCONFIG
#define RT_LWIP_CHECKSUM_BY_HARDWARE (recommended if supported)
in your rtconfig.h file

further more,
the lwip-head now support the icmp_hardware_checksum so you may have to modify your driver.

some chip will filter ipv6 packages, so you must enable the Receive_All function in those chip,
for example in STM32F2x7/F4x7
ETH_InitStructure.ETH_ReceiveAll = ETH_ReceiveAll_Enable;
is needed.
