NAME
sm —
SMC91Cxx-based Ethernet interfaces
device driver
SYNOPSIS
sm0 at ifpga0 addr 0xb8000000 irq 27
sm0 at isa? port 0x300 irq 10
sm* at mhzc?
sm* at pcmcia? function ?
sm* at nubus?
DESCRIPTION
The
sm device driver supports SMC91C9x-based and
SMC91C1xx-based Ethernet interfaces.
The ifpga0 attachment of the
sm driver supports SMC91C9x-based
Ethernet interface on the ARM Integrator/CP board.
The ISA attachment of the
sm driver supports any
SMC91C9x-based Ethernet interface on the ISA bus, including the EFA
Info*Express SVC VLB interface, and the on-board SMC91C9x Ethernet found in
many embedded PCs and laptop docking stations.
The mhzc attachment of the
sm driver supports the Megahertz
combo Ethernet and modem card.
The PCMCIA attachment of the
sm driver supports Megahertz
X-JACK Ethernet cards.
The nubus attachment of the
sm driver supports SMC-based
Ethernet cards for the macintosh.
The SMC91C1xx supports the MII interface and so the list of supported media
depends on several factors, including which PHY is attached. The SMC91C9x
supports AUI and UTP media types.
To enable the AUI media, select the
10base5 or
aui media type with
ifconfig(8)'s
media directive. To select UTP, select the
10baseT or
utp media type.
ifconfig(8)'s
-m option will display the full list of supported
media directives for a particular configuration.
DIAGNOSTICS
- sm0: unable to read MAC address from
CIS
- This indicates that the Ethernet address, which is stored
in the CIS information on the Megahertz X-JACK PCMCIA Ethernet card, is
corrupted.
