This Gigabit Ethernet Controller driver API controls - * 1) Operations (i.e. port init, start, reset etc'). - * 2) Data flow (i.e. port send, receive etc'). - * Each Gigabit Ethernet port is controlled via ETH_PORT_INFO - * struct. - * This struct includes user configuration information as well as - * driver internal data needed for its operations. - * - * Supported Features: - * - This low level driver is OS independent. Allocating memory for - * the descriptor rings and buffers are not within the scope of - * this driver. - * - The user is free from Rx/Tx queue managing. - * - This low level driver introduce functionality API that enable - * the to operate Marvell's Gigabit Ethernet Controller in a - * convenient way. - * - Simple Gigabit Ethernet port operation API. - * - Simple Gigabit Ethernet port data flow API. - * - Data flow and operation API support per queue functionality. - * - Support cached descriptors for better performance. - * - Enable access to all four DRAM banks and internal SRAM memory - * spaces. - * - PHY access and control API. - * - Port control register configuration API. - * - Full control over Unicast and Multicast MAC configurations. - * - * Operation flow: - * - * Initialization phase - * This phase complete the initialization of the ETH_PORT_INFO - * struct. - * User information regarding port configuration has to be set - * prior to calling the port initialization routine. For example, - * the user has to assign the port_phy_addr field which is board - * depended parameter. - * In this phase any port Tx/Rx activity is halted, MIB counters - * are cleared, PHY address is set according to user parameter and - * access to DRAM and internal SRAM memory spaces. - * - * Driver ring initialization - * Allocating memory for the descriptor rings and buffers is not - * within the scope of this driver. Thus, the user is required to - * allocate memory for the descriptors ring and buffers. Those - * memory parameters are used by the Rx and Tx ring initialization - * routines in order to curve the descriptor linked list in a form - * of a ring. - * Note: Pay special attention to alignment issues when using - * cached descriptors/buffers. In this phase the driver store - * information in the ETH_PORT_INFO struct regarding each queue - * ring. - * - * Driver start - * This phase prepares the Ethernet port for Rx and Tx activity. - * It uses the information stored in the ETH_PORT_INFO struct to - * initialize the various port registers. - * - * Data flow: - * All packet references to/from the driver are done using PKT_INFO - * struct. - * This struct is a unified struct used with Rx and Tx operations. - * This way the user is not required to be familiar with neither - * Tx nor Rx descriptors structures. - * The driver's descriptors rings are management by indexes. - * Those indexes controls the ring resources and used to indicate - * a SW resource error: - * 'current' - * This index points to the current available resource for use. For - * example in Rx process this index will point to the descriptor - * that will be passed to the user upon calling the receive routine. - * In Tx process, this index will point to the descriptor - * that will be assigned with the user packet info and transmitted. - * 'used' - * This index points to the descriptor that need to restore its - * resources. For example in Rx process, using the Rx buffer return - * API will attach the buffer returned in packet info to the - * descriptor pointed by 'used'. In Tx process, using the Tx - * descriptor return will merely return the user packet info with - * the command status of the transmitted buffer pointed by the - * 'used' index. Nevertheless, it is essential to use this routine - * to update the 'used' index. - * 'first' - * This index supports Tx Scatter-Gather. It points to the first - * descriptor of a packet assembled of multiple buffers. For example - * when in middle of Such packet we have a Tx resource error the - * 'curr' index get the value of 'first' to indicate that the ring - * returned to its state before trying to transmit this packet. - * - * Receive operation: - * The eth_port_receive API set the packet information struct, - * passed by the caller, with received information from the - * 'current' SDMA descriptor. - * It is the user responsibility to return this resource back - * to the Rx descriptor ring to enable the reuse of this source. - * Return Rx resource is done using the eth_rx_return_buff API. - * - * Transmit operation: - * The eth_port_send API supports Scatter-Gather which enables to - * send a packet spanned over multiple buffers. This means that - * for each packet info structure given by the user and put into - * the Tx descriptors ring, will be transmitted only if the 'LAST' - * bit will be set in the packet info command status field. This - * API also consider restriction regarding buffer alignments and - * sizes. - * The user must return a Tx resource after ensuring the buffer - * has been transmitted to enable the Tx ring indexes to update. - * - * BOARD LAYOUT - * This device is on-board.
