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
Thesm
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.
MEDIA SELECTION
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.
