smSMC91C9x and SMC91C1xx-based 10/100 Ethernet device

sm0 at isa? port 0x300 irq 10
sm* at pcmcia?
sm* at nubus?
nsphy* at mii?

The sm device driver supports SMC91C9x and SMC91C1xx-based Ethernet interfaces.

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 PCMCIA attachment of the sm driver supports Megahertz X-JACK Ethernet cards, NewMedia BASICS Ethernet cards, and SMC EtherEZ 8020 series cards.

The NuBus attachment of the sm driver supports SMC-based Ethernet cards for mac68k.

The SMC91C1xx supports the following media types:

autoselect
Enable autoselection of the media type and options. The user can manually override the autoselected mode by adding media options to the appropriate hostname.if(5) file.
10baseT
Set 10Mbps operation. The mediaopt option can also be used to select either full-duplex or half-duplex modes.
100baseTX
Set 100Mbps (Fast Ethernet) operation. The mediaopt option can also be used to select either full-duplex or half-duplex modes.

The SMC91C9x supports AUI and UTP media types:

To enable the AUI media, select the or media type with ifconfig(8)'s ‘media’ directive. To select UTP, select the or media type.

For more information on configuring this device, see ifconfig(8).

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.
