	1. use BL51 OVERLAY
	Delete:
	The fllowing function should be delete from call tree function 'main':
	RTLSendPacket RTLReceivePacket EtherInput EtherOutput

	Add:
	EtherOutput	to	IPOutput	and	IPInput
	EtherInput	to	NetIfTimer
	RTLSendPacket	to	EtherOutput
	RTLReceivePacket	to EtherInput

	2. define all these func as reentrant
