SMC91C92_CS(S)                                     SMC91C92_CS(S)



NAME
       smc91c92_cs - SMC 91cxx device driver

SYNOPSIS
       insmod      smc91c92_cs.o     [pc_debug=n]     [if_port=n]
       [irq_list=i,j,...]

DESCRIPTION
       Smc91c92_cs is the low-level Card Services driver for  SMC
       91c92,  91c94,  91c96,  and  91c100 based PC Card ethernet
       adapters.  When this driver is  attached  to  a  card,  it
       allocates the next available ethernet device (eth0..eth#).
       This device name will be reported in the kernel log  file,
       and passed on to cardmgr(r).

       With  the  default  transceiver  setting,  the driver will
       attempt to continuously autodetect  the  transceiver  type
       (10base2 or 10baseT).  There should normally only be a one
       or two  second  lag  before  the  correct  transceiver  is
       selected.   On  particularly noisy or busy networks, it is
       possible for the detection logic to incorrectly toggle the
       transceiver  type.   If  this becomes a problem, it may be
       necessary to explicitly select the interface type when the
       module is loaded or with the ifport command.

PARAMETERS
       pc_debug=n
              Selects the PCMCIA debugging level.  This parameter
              is only available if the module  is  compiled  with
              debugging enabled.  A non-zero value enables debug-
              ging.

       if_port=n
              Selects the  transceiver  type.   0  is  autodetect
              (10baseT  or 10base2), 1 is 10baseT (twisted pair),
              and 2 is 10base2 (BNC, or thin net).   The  default
              is 0 (autodetect).

       irq_list=i,j,...
              Specifies  the  set of interrupts that may be allo-
              cated by this driver.

DIAGNOSTICS
       eth#: interrupt(t) dropped!
              Indicates that the driver did not receive an inter-
              rupt notification for some reason.  The driver will
              poll  the  card  (with  a  significant  performance
              penalty)  if the problem persists.  The most likely
              cause is an interrupt conflict and/or  host  bridge
              configuration problem.
