NAME

       3c574_cs  -  3Com 3c574 Etherlink XL 10/100 PC Card device
       driver

SYNOPSIS

       insmod      3c574_cs.o      [pc_debug=n]       [if_port=n]
       [irq_list=i,j,...]  [full_duplex=n] [max_interrupt_work=n]

DESCRIPTION

       3c574_cs is the low-level Card  Services  driver  for  the
       3Com  3c574  EtherLink  XL  PCMCIA ethernet adapter.  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(8).

       The  driver  uses the N-Way autonegotiating transceiver to
       negotiate the speed and duplex of the  network  link.   If
       the  link  partner  does not support negotiation, only the
       link speed is detected.

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.  Only 0, 1, and 4 are
              acceptable values, other values  return  an  error.
              This  actual  value  specificed  is  ignored -- the
              autonegotiating transceiver selects the media speed
              and duplex used.

       irq_list=i,j,...
              This  option  limits the set of interrupts that may
              be allocated by this driver.  The  default  is  all
              normally-usable IRQs.

       full_duplex=n
              This  flag determines if only full-duplex modes are
              advertised.  It defaults to 0 (false).

       max_interrupt_work=work-limit
              This option selects the maximum amount of work han­
              dled  during  each interrupt.  Each received packet
              counts as  one  unit  of  work,  as  does  updating
              statistics   counters  and  handling  errors.   The
              default is 32.

DIAGNOSTICS

       eth#: interrupt(s) 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.
