Driver for AMD PCNET (AMD-79c97x) compatible Ethernet adapters
Syntax:
io-pkt-variant -d pcnet [option[,option ...]] ...
where variant is one of v4, v4-hc, or
v6-hc.
Options:
Note:
Use commas, not spaces, to separate the options.
- connector=0|1|2|3
- Network cable connector type:
- 0
- BNC
- 1
- UTP
- 2
- AUI
- 3
- FIBER
- deviceindex=0xXXXX
- Only attach to device with this PCI index.
- did=0xXXXX
- PCI device ID. The default is
automatically detected on supported hardware.
- dma=num
- The DMA channel.
- 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.
- hpna
- Use HPNA phy.
- iftype=num
- Interface type (from <net/if_types.h>). The default is
IFT_ETHER.
- iorange=0xXXXXXXXX
- The I/O base address.
- irq=num
- IRQ of the interface.
- lan=num
- LAN number. The default is 0.
- mac=XXXXXXXXXXXX
- MAC address of the controller. The default is
automatically detected on supported hardware.
- media=num
- Media type (from <hw/nicinfo.h>).
The default is NIC_MEDIA_802_3.
- memrange=0xXXXXXXXX
- Register base physical memory address.
- mmap
- Use memory-mapped registers. The default is IO mapped.
- mru=num
- Maximum receive unit. The default is 1514.
- mtu=num
- Maximum transmission unit. The default (1514) is
automatically detected on supported hardware.
- nomulticast
- Disables the driver from sending or receiving multicast
packets. By default, multicast is enabled.
- pci=0xXXXX
- PCI index of the controller. The default is
automatically detected on supported hardware.
- phy=num
- Address of the connected PHY device.
- priority=N
- Priority of the driver event-thread. The default is 21.
- probe_phy=0|1
- Select whether or not to probe the PHY at regular intervals. For the
default value of 0, the PHY is polled
only at regular intervals when the interface is down or doesn't receive any
packets over the polling interval.
If you specify 1, the PHY is always probed at regular intervals
to see if the duplex and/or speed of the connection has changed.
- promiscuous
- Enable promiscuous mode. The default is off.
- receive=num
- Set the number of receive descriptors/buffers.
The default is 64.
- speed=10|100
- 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).
- transmit=num
- Number of transmit descriptors/buffers.
The default is 128.
- uptype=name
- Interface name. The default is "en".
- verbose or
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.
- vid=0xXXXX
- PCI vendor ID of the controller. The default is
automatically detected on supported hardware.
Description:
The devn-pcnet.so driver controls AMD PCNET (AMD-79c97x)
compatible Ethernet adapters.
This is a legacy io-net driver;
its interface names are in the form enX, where
X is an integer.
Note:
- If the device enumerators (see
enum-devices)
don't recognize your device, try explicitly specifying
the device ID with the did option when you start the driver.
- This driver doesn't support Fiber PCNET cards with the AM79C971KC chip.
- We don't recommend that you use devn-pcnet.so on the
BCM1250 platform, because it can lose receive interrupts.
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.
Examples:
Start io-pkt-v4-hc using the AMD PCNET driver:
io-pkt-v4-hc -d pcnet
ifconfig en0 10.1.0.184
Files:
- /dev/io-net
- The directory where, by default, drivers and protocol modules add
entries.
