SNC(4) BSD/i386 Kernel Interfaces Manual SNC(4)NAMEsnc -- National Semiconductor DP8393X SONIC Ethernet adapter driverSYNOPSISdevice isa device sncDESCRIPTIONThe snc driver provides support for the National Semiconductor SONIC Ethernet adapters.HARDWAREThe snc driver supports the following cards: o National Semiconductor DP83934AVQB o NEC PC-9801-83 o NEC PC-9801-84 o NEC PC-9801-103 o NEC PC-9801-104 o NEC PC-9801N-15 o NEC PC-9801N-25 o NEC PC-9801N-J02 PCMCIA o NEC PC-9801N-J02R PCMCIA The snc driver also includes support for the National Semiconductor NS46C46 as 64 * 16 bits Microwave Serial EEPROM.IMPLEMENTATION NOTESAccessing 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 snc driver supports the PC-98 C-Bus, and PnP buses. Support is also provided for the legacy C-Bus.DIAGNOSTICSThe 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.SEE ALSOnetintro(4), bus_alloc_resource_any(9)HISTORYThe snc driver was ported from NetBSD by Motomichi Matsuzaki <mzaki@e-mail.ne.jp> and Hiroshi Yamashita <bluemoon@msj.biglobe.ne.jp>. It first appeared in FreeBSD 4.2. This manual page first appeared in FreeBSD 5.3.AUTHORSThis manual page was written by Tom Rhodes <trhodes@FreeBSD.org>.BUGSCurrently the snc driver only works on the PC-98 architecture. It should probably work on the i386 architecture as well.BSDSeptember 4, 2004 BSD
