`devn-gt64260.so`

Driver for Marvell GT64260 Ethernet controller

Syntax:

io-net -d gt64260 [option[,option ...]] ... &

Options:

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

deviceindex=num: Specifies the index of the Ethernet device to attach to. If no index is specified, the driver automatically initializes and attaches to all 3 channels.
duplex=0/1: Duplex mode. Use 0 for half-duplex mode and 1 for full-duplex mode.
mac=XXXXXXXXXXXX: Specifies the hardware MAC address. This option is mandatory.
memrange=0xXXXXXXXX: Register base memory address. There is no default; this option is mandatory.
mtu=X: Maximum transmission unit.
nomulticast: Ignore requests to receive multicast addresses.
promiscuous: Enable promiscuous mode.
receive=num: Set the number of receive descriptors/buffers. The default is 64.
rmii=0: Use MII phy. Default is 1=ON (Use RMII phy).
speed=10/100: Media data rate.
transmit=num: Set the number of transmit descriptors/buffers. The default is 128.
verbose=num: Be verbose. Specify num for more verbosity (num can be 1-4, the higher the number, the more detailed the output). The output goes to slogger, invoke sloginfo to view.

A MAC address must be specified on the command line. In auto-initialization mode, (where "deviceindex" isn't specified) the MAC address for each channel is derived from the specified MAC address plus the channel index.

Description:

The devn-gt64260.so driver controls Marvell Ethernet controllers.

Examples:

Start io-net on the Motorola MVP board, auto-initializing all three channels:

Channel 1 will be assigned a MAC address of 001100bead01, and channel 2 will be assigned a MAC address of 001100bead02.

io-net -d gt64260 memrange=0xf8000000,rmii=0,mac=001100bead00 -ptcpip

Start io-net on the Marvell EV-64260A-BP board, using channel 0 and channel 2:

io-net -d gt64260 memrange=0xf8000000,mac=001100bead00,deviceindex=0 \
-dgt64260 memrange=0xf8000000,mac=001100bead22,deviceindex=2
-ptcpip
