AFE(7D)AFE(7D)NAMEafe - ADMtek Fast Ethernet device driver
The afe driver is a multi-threaded, loadable, clonable, GLD-based
STREAMS driver supporting the Data Link Provider Interface dlpi(7P) on
ADMtek (now Infineon) Centaur and Comet Fast Ethernet controllers.
APPLICATION PROGRAMMING INTERFACE
The afe driver can be used as either a "style 1" or a "style 2" Data
Link Service Provider. Physical points of attachment (PPAs) are inter‐
preted as the instance number of the afe controller as assigned by the
Solaris operating environment.
The relevant fields returned as part of a DL_INFO_ACK response are:
o Maximum SDU is 1500.
o Minimum SDU is 0.
o The dlsap address length is 8.
o MAC type is DL_ETHER.
o SAP length is -2. The 6-byte physical address is followed
immediately by a 2-byte SAP.
o Service mode is DL_CLDLS.
o Broadcast address is the 6-byte Ethernet broadcast address
If the SAP provided is zero, then IEEE 802.3 mode is assumed and out‐
bound frames will have the frame payload length written into the type
field. Likewise, inbound frames with a SAP between zero and 1500 are
interpreted as IEEE 802.3 frames and delivered to any streams that are
bound to SAP zero (the 802.3 SAP).
The following properties may be configured using either ndd(1M) or
the afe.conf configuration file as described by driver.conf(4):
Enables (default) or disables IEEE 802.3u auto-negotiation of link
speed and duplex settings. If enabled, the device negotiates among
the supported (and configured, see below) link options with the
link partner. If disabled, at least one of the link options below
must be specified. The driver selects the first enabled link option
according to the IEEE 802.3u specified preferences.
Enables the 100 BaseT4 link option. (Note that most hardware does
not support this unusual link style. Also, this uses two pairs of
wires for data, rather than one.)
Enables the 100 Base TX full-duplex link option. (This is generally
the fastest mode if both link partners support it. Most modern
equipment supports this mode.)
Enables the 100 Base TX half-duplex link option. (Typically used
when the link partner is a 100 Mbps hub.)
Enables the 10 Base-T full-duplex link option. (This less-fre‐
quently used mode is typically used when the link partner is a 10
Enables the 10 Base-T half-duplex link option. (This is the fall-
back when no other option is available. It is typically used when
the link partner is a 10 Mbps hub or is an older network card.)
