.Sh NAME
.Nm sbsh
.Nd "Granch SBNI16 SHDSL modem device driver"
.Sh SYNOPSIS
.Cd "device sbsh"
.Sh DESCRIPTION
The
.Nm
driver provides support for an internal PCI modem SBNI16-SHDSL. A device
is introduced to OS as common ethernet-like netcard which must be
configured with
.Xr ifconfig 8
(all standard network interface parameters could be set). Modem-specific
parameters (master/slave mode, line rate etc.) must be set with the
sb16config utility before interface activation.
.Sh FILES
The sources for the driver reside in:

.Sh DIAGNOSTICS
.Bl -diag
.It "sbsh%d: couldn't map memory"
.It "sbsh%d: couldn't map interrupt"
.It "sbsh%d: couldn't set up irq"
A fatal initialization error has occurred.
.It "sbsh%d: unable to load firmware"
A fatal error has occurred while sb16config running.
.It "sbsh%d: firmware wasn't loaded"
ifconfig...up has failed because device hadn't been configured with
sb16config.
.It "sbsh%d: transmit timeout"
.It "sbsh%d: interrupt posted but not delivered"
Probably, a hardware error or incompatibility.
.It "sbsh%d: unable to get mbuf"
.It "sbsh%d: unable to get mbuf cluster"
