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]
       [auto_polarity=n] [max_interrupt_work=n]

DESCRIPTION
       3c574_cs is the low-level Card Services driver for the 3Com 3c574 EtherLink XL PCMCIA eth-
       ernet  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 debugging.

       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).

       This flag can be used to control the transceiver's auto polarity
	      detection capability.  Some Cisco Catalyst switches are  known  to  interact  badly
	      with this feature in 10baseT mode.  It defaults to 1 (enabled).

       max_interrupt_work=work-limit
	      This option selects the maximum amount of work handled 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 interrupt notification for some rea-
	      son.  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.
