/*
 * A single CopyEngine (CE) comprises two "rings":
 *   a source ring
 *   a destination ring
 *
 * Each ring consists of a number  * uses this netbufs  locate thenetwork
 * an address, length, and meta-data.
 *
 * Typically, one side of the PCIe/AHB/SNOC interconnect (Host or Target)
 * controls one ring and the other side controls the other ring.
 * The source side chooses when to initiate a transfer and it
 * chooses what to send (buffer address, length). The destination
 * side keeps a supply of "anonymous receive buffers" available and
 * it handles incoming data as it arrives (when the destination
 * receives an interrupt).
 *
 *   *firmware to MAC Rx ring. Firmware then delivers IN_ORD_IND
 * send a smallo specific (re-ordered) buffers.
 * "gathers" these and they end up in a single destination buffer
 * with a single interrupt.
 *
 * There are several "contexts" managed by this layer -- more, it
 * may seem -- than should be needed. These are provided mainly for
 * maximum flexibility and especially to facilitate a simpler HIF
 
 * contexts. These are supplied by the caller when a recv, send,

*java.lang.StringIndexOutOfBoundsException: Range [8, 7) out of bounds for length 67
 * (or sendlist) is sent and when a buffer is enqueued for recv.
