if_ene

NAME

if_ene - Novell/Eagle NE2000 network interface driver

ROUTINES

eneattach( ) - publish the ene network interface and initialize the driver and device
enePut( ) - copy a packet to the interface.
eneShow( ) - display statistics for the NE2000 ene network interface

DESCRIPTION

This module implements the Novell/Eagle NE2000 network interface driver. There is one user-callable routine, eneattach( ).

BOARD LAYOUT

The diagram below shows the relevant jumpers for VxWorks configuration. Other compatible boards will be jumpered differently; many are jumperless.

EXTERNAL INTERFACE

There are two user-callable routines:

eneattach( )

publishes the ene interface and initializes the driver and device.

eneShow( )

displays statistics that are collected in the interrupt handler.

See the manual entries for these routines for more detail.

SYSTEM RESOURCE USAGE

- one interrupt vector
    - 16 bytes in the uninitialized data section (bss)
    - 1752 bytes (plus overhead) of malloc'ed memory per unit attached

CAVEAT

This driver does not enable the twisted-pair connector on the Taiwanese ETHER-16 compatible board.

eneattach( )

NAME

eneattach( ) - publish the ene network interface and initialize the driver and device

SYNOPSIS

STATUS eneattach
    (
    int unit,   /* unit number */
    int ioAddr, /* address of ene's shared memory */
    int ivec,   /* interrupt vector to connect to */
    int ilevel  /* interrupt level */
    )

DESCRIPTION

This routine attaches an ene Ethernet interface to the network if the device exists. It makes the interface available by filling in the network interface record. The system will initialize the interface when it is ready to accept packets.

RETURNS

OK or ERROR.

enePut( )

NAME

enePut( ) - copy a packet to the interface.

SYNOPSIS

#ifdef BSD43_DRIVER static void enePut
    (
    int unit
    )

DESCRIPTION

Copy from mbuf chain to transmitter buffer in shared memory.

eneShow( )

NAME

eneShow( ) - display statistics for the NE2000 ene network interface

SYNOPSIS

void eneShow
    (
    int  unit, /* interface unit */
    BOOL zap   /* 1 = zero totals */
    )

DESCRIPTION

This routine displays statistics about the ene Ethernet network interface. It has two parameters:

unit

interface unit; should be 0.

zap

if 1, all collected statistics are cleared to zero.

RETURNS

N/A
