Data Structures for Drivers                     mac_callbacks(9S)



NAME
     mac_callbacks - MAC callbacks data structure

SYNOPSIS
     #include 


INTERFACE LEVEL
     Solaris architecture specific (Solaris DDI)

DESCRIPTION
     The mac_callbacks data  structure  is  used  by  MAC  device
     drivers  to  expose  their  entry points to the MAC layer. A
     pointer to an instance of  the  mac_callbacks  structure  is
     passed through the m_callbacks field of the mac_register(9S)
     structure as part of the registration  of  a  device  driver
     instance through mac_register(9F).

STRUCTURE MEMBERS
       uint_t          mc_callbacks;   /* Denotes which callbacks are set */
       mac_getstat_t   mc_getstat;     /* Get the value of a statistic */
       mac_start_t     mc_start;       /* Start the device */
       mac_stop_t      mc_stop;        /* Stop the device */
       mac_setpromisc_t mc_setpromisc; /* Enable or disable promiscuous mode */
       mac_multicst_t  mc_multicst;    /* Enable or disable a multicast addr */
       mac_unicst_t    mc_unicst;      /* Set the unicast MAC address */
       mac_tx_t        mc_tx;          /* Transmit a packet */
       mac_ioctl_t     mc_ioctl;       /* Process an unknown ioctl */
       mac_getcapab_t  mc_getcapab;    /* Get capability information */
       mac_set_prop_t  mc_setprop;     /* Set property value */
       mac_get_prop_t  mc_getprop;     /* Get property value */
       mac_prop_info_t mc_propinfo;    /* Get property attributes */



     Below are descriptions of the members of  the  mac_callbacks
     structure that are visible to the device driver.

     mc_callbacks

         Flags specifying which ones of the optional entry points
         are  implemented  by the driver. The following flags are
         supported:

         MC_IOCTL

             Set by the driver when the mc_ioctl() entry point is
             present.


         MC_GETCAPAB

Data Structures for Drivers                     mac_callbacks(9S)



             Set by the driver when the mc_getcapab() entry point
             is present.


         MC_SETPROP

             Set by the driver when the mc_setprop() entry  point
             is present.


         MC_GETPROP

             Set by the driver when the mc_getprop() entry  point
             is present.


         MC_PROPINFO

             Set by the driver when the mc_propinfo() entry point
             is present.


         MC_PROPERTIES

             Set by a  driver  which  implements  all  properties
             entry   points   (mc_setprop(),   mc_getprop(),  and
             mc_propinfo()).   Setting   MC_PROPERTIES   is   the
             equivalent  of  setting  the three flags MC_SETPROP,
             MC_GETPROP, and MC_PROPINFO.



     mc_getstat

         pointer to driver entry point


     mc_start

         pointer to driver entry point


     mc_stop

         pointer to driver entry point


     mc_setpromisc

         pointer to driver entry point

     mc_propinfo

         pointer to driver entry point
