Driver for SMC91c9x and SMC91c1xx (SMC9000) Ethernet controllers

v6-hc.

|
Use commas, not spaces, to separate the options. |
- connector=0|1|2
- Network cable connector type:
- 0
- BNC
- 1
- UTP
- 2
- AUI
The default is UTP.
- duplex=0|1
- Half (0) or full (1) duplex mode. The default is
automatically detected on supported hardware.
If you specify duplex, specify speed as well;
if duplex alone is specified, it is ignored and both speed and duplex
are auto-negotiated.
- iftype=num
- Interface type (from <net/if_types.h>). The default is
IFT_ETHER.
- iorange=0xXXXXXXXX
- The I/O base address. The 0xXXXXXXXX parameter
must be a hex address (e.g. 0x320). The default is
automatically detected on supported hardware (but see caution below).
- irq=num
- IRQ of the interface.
- lan=num
- LAN number. The default is 0.
- mac=XXXXXXXXXXXX
- MAC address of the controller. You must set the MAC address for this
controller.
- media=num
- Media type (from <hw/nicinfo.h>).
The default is NIC_MEDIA_802_3.
- mru=num
- Maximum receive unit. The default is 1514.
- mtu=num
- Maximum transmission unit. The default (1514) is
automatically detected on supported hardware.
- nomulticast
- Disable multicast support.
- phy=num
- Address of the connected PHY device.
- pktque=num
- Set the maximum number of packets that will be queued for transmission
in system RAM. The default is 100.
- pmmparent=string
- Override the parent component of the path to register for
Power Management.
- priority=N
- Priority of the driver event-thread. The default is 21.
- promiscuous
- Enable promiscuous mode. The default is off.
- speed=10|100
- Force media data rate (10Mbit or 100Mbit operation). The default is
automatically detected on supported hardware.
If you specify speed, specify duplex as well;
if speed alone is specified, the specified speed will be correctly set,
but duplex will default to half (0).
- txcap=num
- Set the maximum number of packets that will be
queued for transmission in on-chip SRAM. On the 91c111
the default is 1, since the amount of on-chip memory is limited
to 4 packets. Limiting the number of transmit packets prevents
packet transmission from using up all the SRAM, and makes more
SRAM available for receive. This prevents packet overruns on receive.
For other chips with more on-chip SRAM, the limit is 32 packets.
- uptype=name
- Interface name. The default is “en”.
- variant=name
- Set up the driver for a specific board variant. Currently supported variants are
generic, assabet, dbpxa250dp,, graphicsmaster,
innovator, and pxa250tmdp.
- verbose
verbose=num
- Be verbose. Specify num for more verbosity (num can be 1-4, the higher
the number, the more detailed the output). The default is 0.
The output goes to slogger;
invoke sloginfo to view it.
- width=8|16|32
- I/O access width (8, 16, or 32 bits). The default is 16.
|
An incorrect width size can lock up the card or the platform CPU.
If you specify the variant option, the width option
may be ignored.
|
The devn-smc9000.so driver controls SMC 91c9x/91c1xx compatible
Ethernet adapters.
This is a legacy io-net driver;
its interface names are in the form enX, where
X is an integer.
|
This driver can't always detect the correct irq and iorange
options, especially for ISA devices. To be sure, always specify irq and
iorange when using this driver. |
Some devices support hardware checksums, although some might do so in
only one direction; to determine if your device does, type:
ifconfig enX
and look for the following in the list of supported options:
- ip4csum, ip4csum-rx, ip4csum-tx
- tcp4csum, tcp4csum-rx, tcp4csum-tx
- tcp6csum, tcp6csum-rx, tcp6csum-tx
- udp4csum, udp4csum-rx, udp4csum-tx
- udp6csum, udp6csum-rx, udp6csum-tx
You can then use
ifconfig
to enable or disable whichever of these options your device supports.
Start io-pkt-v4-hc using the SMC9000 driver:
io-pkt-v4-hc -dsmc9000 iorange=0x200,irq=5
ifconfig en0 10.1.0.184
- /dev/io-net
- The directory where, by default, drivers and protocol modules add
entries.
For more information, see the documentation for
io-pkt*.
You must specify the mac option when using this driver.
devn-*,
devnp-*,
ifconfig,
io-pkt*
