NAME
ifmedia - network interface media settings
SYNOPSIS
#include <sys/socket.h>
#include <net/if.h>
#include <net/if_media.h>
DESCRIPTION
The ifmedia interface provides a consistent method for querying and
setting network interface media and media options. The media is
typically set using the ifconfig(8) command.
There are currently four link types supported by ifmedia:
IFM_ATM Asynchronous Transfer Mode
IFM_CARP Common Address Redundancy Protocol
IFM_ETHER Ethernet
IFM_IEEE80211 IEEE802.11 Wireless LAN
The following sections describe the possible media settings for each link
type. Not all of these are supported by every device; refer to your
device's manual page for more information.
The lists below provide the possible names of each media type or option.
The first name in the list is the canonical name of the media type or
option. Additional names are acceptable aliases for the media type or
option.
COMMON MEDIA TYPES AND OPTIONS

only has meaning if the device is normally not full-
duplex. [full-duplex]
