Intro -- introduction to MDI visible structures

Synopsis

   #include <sys/types.h>
   #include <sys/ddi.h>
   #include <sys/mdi.h>

This section describes the kernel data structures a developer might need to use in an MDI driver.

MDI structures store data for:

multicast addresses:

mac_mcast(D4mdi)
the multicast address state structure that is returned by the mdi_get_mctable(D3mdi) function
media specific statistics; the MACIOC_GETSTAT ioctl requests that the MDI driver return these statistics structures:

mac_stats_eth(D4mdi)
Ethernet and IEEE 802.3 CSMA/CD

mac_stats_fddi(D4mdi)
ANSI Fiber Distributed Data Interface (FDDI)

mac_stats_isdn(D4mdi)
Integrated Services Digital Network (ISDN)

mac_stats_tr(D4mdi)
IEEE 802.5 Token Passing Ring
