/*
* A single CopyEngine ( CE ) comprises two " rings " :
* a source ring
* a destination ring
*
* Each ring consists of a number * uses this netbufs locate the network
* 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 small o 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 ,
* or watermark handler is established and they are echoed back to
* the caller when the respective callbacks are invoked . There is
* java.lang.StringIndexOutOfBoundsException: Range [8, 7) out of bounds for length 67
* ( or sendlist ) is sent and when a buffer is enqueued for recv .
* These per - transfer contexts are echoed back to the caller when
* the buffer is sent / received .
