NAME
snc - National Semiconductor DP8393X SONIC Ethernet adapter driverSYNOPSIS
device isa device sncDESCRIPTION
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.

Currently the driver only works on the PC-98 architecture. It should probably work on the i386 architecture as well.Contenus ©2006-2024 Benjamin Poulain
