SFE(7D)SFE(7D)NAMEsfe - SiS900 series Fast Ethernet device driver
SYNOPSIS
/dev/sfe
DESCRIPTION
The sfe driver is a loadable, clonable, GLD-based STREAMS driver sup‐
porting the Data Link Provider Interface dlpi(7P) on Silicon Integrated
Systems 900 series Fast Ethernet controllers.
APPLICATION PROGRAMMING INTERFACE
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
(ff:ff:ff:ff:ff:ff).
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).
PROPERTIES
The following properties may be configured using either ndd(1M) or
the sfe.conf configuration file as described by driver.conf(4):
adv_100fdx_cap
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.)
adv_100hdx_cap
Enables the 100 Base TX half-duplex link option. (Typically used
when the link partner is a 100 Mbps hub.)
adv_10fdx_cap
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
Mbps switch.)
adv_10hdx_cap
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.)
