3C575_CB(4)                                           3C575_CB(4)

NAME
       3c575_cb  -  3Com 3c575 Etherlink XL 10/100 CardBus device
       driver

SYNOPSIS
       insmod 3c575_cb.o [pc_debug=n]

DESCRIPTION
       3c575_cb is the low-level Card  Services  driver  for  the
       3Com  3c575  EtherLink  XL CardBus ethernet adapter.  When
       this driver is attached to a card, it allocates  the  next
       available  ethernet device (eth0..eth#).  This information
       for this card will be reported in the kernel log file, and
       the device name 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.

       If the on-card EEPROM is programmed for a full-duplex (FD)
       link,  only  FD media types are advertised and the link is
       assumed to be full-duplex.

PARAMETERS
       rx_copybreak=n
              Set the breakpoint for copying incoming frames into
              reduced-sized packet buffers.  The default value of
              200 bytes is reasonable for most systems.

       max_interrupt_work=n
              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  value  of  20  should  only  need  to   be
              increased on very slow machines.  If "too much work
              at interrupt" messages are logged the system  power
              management  configuration  should  be  set  to full
              speed rather than increasing this value.
