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 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 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 reason.  The driver will poll the card (with a signifi-
	      cant  performance penalty) if the problem persists.  The most likely cause is an interrupt conflict and/or host bridge configuration
	      problem.
