`devn-ppc405.so`

Driver for IBM PPC405 on-chip Ethernet controllers

Syntax:

io-net -d ppc405 mac=XXXXXXXXXXXX[,option[,option...]]
       ... &

Options:

Use commas (,) to separate the options (not spaces).

deviceindex

The instance of the on-chip Ethernet controller to attach to. By default, the driver attempts to detect and attach to all on-chip Ethernet controllers. If there's more than one device on the board (e.g. en0, en1, en2, etc.), setting this option to deviceindex=0 initializes the first device only.

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.

mac=XXXXXXXXXXXX

MAC address of the controller. You must specify a MAC address via this option.

You should specify the MAC address of the first controller; the driver automatically increments the MAC address for additional controllers, if they're present.

mii

Select the standard MII interface.

mtu=N

Maximum transmission unit. The default is 1514.

phy=N

Address of the connected PHY device.

priority=N

Priority of driver's event handler thread. The default is 21.

promiscuous

Enable reception of all packets on the wire, irrespective of destination MAC address. The default is off.

receive=N

Set the number of receive descriptors. The default is 16, max is 256.

regbase=N

Physical address of the first EMAC controller (EMACO).

rmii

Select reduced MII interface.

rxde_irq=N

Hardware interrupt number for MAL receive descriptor error events. The default is automatically detected on supported hardware.

rxeob_irq=N

Hardware interrupt number for MAL packet reception events. The default is automatically detected on supported hardware.

smii

Select serial MII interface.

speed=N

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=N

Set the number of transmit descriptors. The default is 32, the max is 256.

txde_irq=N

Hardware interrupt number for MAL transmit descriptor error events. The default is automatically detected on supported hardware.

verbose verbose=N

Be verbose. Specify N for more verbosity (the higher the number, the more detailed the output). The output goes to slogger, invoke sloginfo to view.

Description:

The devn-ppc405.so driver controls IBM PPC405 on-chip ethernet controllers.

Examples:

Start io-net using the devn-ppc405.so driver and the full TCP/IP stack:

io-net -dppc405 mac=0004ACE313DF -ptcpip 
ifconfig en0 192.168.0.10

/dev/io-net: The directory where, by default, drivers and protocol modules add entries. For more information, the documentation for io-net.
