NAME

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

SYNOPSIS

       insmod   3c574_cs.o  [pc_debug=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.   To  monitor  or
       override the autonegotiation process, see mii-tool(8).

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.

       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).

       auto_polarity=n
              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   significant  performance  penalty)  if  the  problem
              persists.  The most likely cause is an interrupt conflict and/or
              host bridge configuration problem.
