void EIP_DLR_processDLRFrame	(	EIP_DLRHandle	dlrHandle,
		uint8_t *	pktBuffer,
		uint8_t	portNum,
		uint16_t	size
	)

Processes a sign on and Neighbor check request frame.

   In case of sign on frames, if size of packet is greater than
   \ref DLR_SIGNON_FRAME_SIZE then the frame is sent directly to host.
   Therefore the 'size' argument must be the size of the incoming frame,
   because it is used as the size of the outgoing frame, only if the
   frame already has maximum size and is sent unchanged but directed to
   the supervisor. Also, 'pktBuffer' passed to the function must provide
   'size'+10 bytes space so that the own MAC and IP addresses can be
   added.

Parameters

dlrHandle	[in] DLR handle
pktBuffer	[in] pointer to bytestream
portNum	[in] Port number wherer the packet arrived
size	[in] size of packet
