.Dd September 4, 2004 .Dt SNC 4 i386 .Os .Sh NAME .Nm snc .Nd National Semiconductor DP8393X SONIC Ethernet adapter driver .Sh SYNOPSIS .Cd device isa .Cd device snc .Sh DESCRIPTION The .Nm driver provides support for the .Tn National .Tn Semiconductor .Tn SONIC Ethernet adapters. .Sh HARDWARE The .Nm driver supports the following cards:
p l -bullet -compact t National Semiconductor DP83934AVQB t NEC PC-9801-83 t NEC PC-9801-84 t NEC PC-9801-103 t NEC PC-9801-104 t NEC PC-9801N-15 t NEC PC-9801N-25 t NEC PC-9801N-J02 PCMCIA t NEC PC-9801N-J02R PCMCIA .El
p The .Nm driver also includes support for the .Tn National .Tn Semiconductor .Tn NS46C46 as 64 * 16 bits Microwave Serial .Tn EEPROM . .Sh IMPLEMENTATION NOTES Accessing .Tn SONIC card data structures and registers as 32 bit values makes code endianness independent. The .Tn SONIC is however always in big-endian mode so it is necessary to ensure that data structures shared between the .Tn CPU and the .Tn SONIC card are always in big-endian order. The .Nm driver supports the .Tn PC-98 C-Bus, and .Tn PnP buses. Support is also provided for the legacy C-Bus. .Sh DIAGNOSTICS The following driver specific error messages may be reported: l -diag t "snc%d: snc_nec16_register_irq: unsupported irq (%d)" The card returned an .Tn IRQ which is not supported by the driver. t "snc%d: invalid packet length %d bytes" An attempt to transfer a data packet failed due to an invalid packet length. .El .Sh SEE ALSO .Xr netintro 4 , .Xr bus_alloc_resource_any 9 .Sh HISTORY The .Nm driver was ported from .Nx by .An -nosplit .An Motomichi Matsuzaki Aq Mt mzaki@e-mail.ne.jp and .An Hiroshi Yamashita Aq Mt bluemoon@msj.biglobe.ne.jp . It first appeared in .Fx 4.2 . This manual page first appeared in .Fx 5.3 . .Sh AUTHORS This manual page was written by .An Tom Rhodes Aq Mt trhodes@FreeBSD.org . .Sh BUGS Currently the .Nm driver only works on the .Tn PC-98 architecture. It should probably work on the i386 architecture as well.
