     35  * Driver specific routines description
     36  *
     37  * Function:
     38  *     ld_hw_interrupt
     39  * Purpose:
     40  *     Routine handler for hardware linkscan interrupt.
     41  * Parameters:
     42  *     unit - Device unit number
     43  *     pbmp - (OUT) Returns bitmap of ports that require hardware re-scan
     44  *
     45  *
     46  * Function:
     47  *     ld_port_link_get
     48  * Purpose:
     49  *     Return current PHY up/down status.
     50  * Parameters:
     51  *     unit - Device unit number
     52  *     port - Device port number
     53  *     hw   - If TRUE, assume hardware linkscan is active and use it
     54  *              to reduce PHY reads.
     55  *            If FALSE, do not use information from hardware linkscan.
     56  *     up   - (OUT) TRUE for link up, FALSE for link down.
     57  *
     58  *
     59  * Function:
     60  *     ld_internal_select
     61  * Purpose:
     62  *     Select the source of the CMIC link status interrupt
     63  *     to be the Internal Serdes on given port.
     64  * Parameters:
     65  *     unit - Device unit number
     66  *     port - Device port number
     67  *

     69  * Function:
     70  *     ld_update_asf
     71  * Purpose:
     72  *     Update Alternate Store and Forward parameters for a port.
     73  * Parameters:
     74  *     unit   - Device unit number
     75  *     port   - Device port number
     76  *     linkup - port link state (0=down, 1=up)
     77  *     speed  - port speed
     78  *     duplex - port duplex (0=half, 1=full)
     79  *
     80  *
     81  * Function:
     82  *     ld_trunk_sw_failover_trigger
     83  * Purpose:
     84  *     Remove specified ports with link down from trunks.
     85  * Parameters:
     86  *     unit        - Device unit number
     87  *     pbmp_active - Bitmap of ports
     88  *     pbmp_status - Bitmap of port status
