SYNOPSIS

device isa device snc

DESCRIPTION

The driver provides support for the National Semiconductor SONIC Ethernet adapters.

HARDWARE

The driver supports the following cards:

• National Semiconductor DP83934AVQB
• NEC PC-9801-83
• NEC PC-9801-84
• NEC PC-9801-103
• NEC PC-9801-104
• NEC PC-9801N-15
• NEC PC-9801N-25
• NEC PC-9801N-J02 PCMCIA
• NEC PC-9801N-J02R PCMCIA

The driver also includes support for the National Semiconductor NS46C46 as 64 * 16 bits Microwave Serial EEPROM

IMPLEMENTATION NOTES

Accessing SONIC card data structures and registers as 32 bit values makes code endianness independent. The SONIC is however always in big-endian mode so it is necessary to ensure that data structures shared between the CPU and the SONIC card are always in big-endian order. The driver supports the PC-98 C-Bus, and PnP buses. Support is also provided for the legacy C-Bus.

DIAGNOSTICS

The following driver specific error messages may be reported:

"snc%d: snc_nec16_register_irq: unsupported irq (%d)"

The card returned an IRQ which is not supported by the driver.

"snc%d: invalid packet length %d bytes"

An attempt to transfer a data packet failed due to an invalid packet length.
