NAME
     sbsh - Granch SBNI16 SHDSL modem device driver


SYNOPSIS
     device sbsh


DESCRIPTION
     The sbsh driver provides support for an internal PCI modem SBNI16-SHDSL.
     A device is introduced to the OS as a common Ethernet-like network card
     which must be configured with 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.


DIAGNOSTICS
     sbsh%d: couldn’t map memory
     sbsh%d: couldn’t map interrupt
     sbsh%d: couldn’t set up irq  A fatal initialization error has occurred.

     sbsh%d: unable to load firmware  A fatal error has occurred while
     sb16config was running.

     sbsh%d: firmware wasn’t loaded  “ifconfig ... up” has failed because
     device has not been configured with sb16config.

     sbsh%d: transmit timeout
     sbsh%d: interrupt posted but not delivered  Probably, a hardware error or
     incompatibility.

     sbsh%d: unable to get mbuf
     sbsh%d: unable to get mbuf cluster  The driver failed to allocate a
     memory buffer.
