Packet received from remote host.

Called by app when a packet is received from a remote host over the network.

Parameters:

	sess	Session associated with received packet
	net_addr	Opaque network address
	net_addrlen	Size of opaque network address
	buf	Pointer to data buffer containing packet
	buflen	Length of received packet

Returns:: Zero for success, non-zero on error
