Routine Description:
	Called by the IPX stack to indicate that the IPX packet was
	received by the NIC dirver.  Only external destined packets are
	indicated by this routine (with the exception of Netbios boradcasts
	that indicated both for internal and external handlers)
Arguments:
	MacBindingHandle	- handle of NIC driver
	MaxReceiveContext	- NIC driver context
	Context				- forwarder context associated with
							the NIC (interface block pointer)
	RemoteAddress		- sender's address
	MacOptions			-
	LookaheadBuffer		- packet lookahead buffer that contains complete
							IPX header
	LookaheadBufferSize	- its size (at least 30 bytes)
	LookaheadBufferOffset - offset of lookahead buffer in the physical
							packet
Return Value:
	None

Routine Description:

		This routine receives control from the IPX driver after one or
		more receive operations have completed and no receive is in progress.
		It is called under less severe time constraints than IpxFwdReceive.
		It is used to process netbios queue

Arguments:
	None
Return Value:
	None

Routine Description:
	Called by the IPX stack to indicate that the IPX packet destined
	to local client was received by the NIC dirver.
Arguments:
	Context				- forwarder context associated with
							the NIC (interface block pointer)
	RemoteAddress		- sender's address
	LookaheadBuffer		- packet lookahead buffer that contains complete
							IPX header
	LookaheadBufferSize	- its size (at least 30 bytes)
Return Value:
	STATUS_SUCCESS - the packet will be delivered to local destination
	STATUS_UNSUCCESSFUL - the packet will be dropped
