NAME

       pcnet_cs - generic NS8390-based PCMCIA Ethernet Driver

SYNOPSIS

       insmod    pcnet_cs.o   [pc_debug=n]   [irq_list=i,j,...]    [if_port=n]
       [full_duplex=n]     [use_big_buf=n]     [use_shmem=n]     [mem_speed=n]
       [delay_output=n] [delay_time=n] [hw_addr=n,n,n,n,n,n]

DESCRIPTION

       Pcnet_cs  is  a  driver for all NS8390-based PCMCIA ethernet cards.  It
       can use either polled IO or a shared memory  window  to  exchange  data
       with  the  card.   The  driver  first tests for a shared memory buffer,
       falling back on polled IO if the memory test fails.  When  this  driver
       is  bound  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).

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,...
              Specifies  the  set  of interrupts that may be allocated by this
              driver.

       if_port=n
              Selects the transceiver type, for Socket EA and IBM CCAE  cards.
              1  is  10baseT  (twisted  pair),  and 2 is 10base2 (BNC, or thin
              net).  The default is 1 (10baseT).

       full_duplex=n
              For DL10022 based  cards  where  pcnet_cs  can’t  find  the  MII
              interface,  this  option  permits  manual  control of the duplex
              setting.  1 is full duplex, and 0 is half duplex; the default is
              0.

       use_big_buf=n
              For  Socket EA cards, a flag indicating if the driver should use
              the large (64K) packet buffer.  The default is 1 (true).

       use_shmem=n
              Selects  shared  memory  versus  polled  IO  mode   for   packet
              transfers.   The  default  is  -1, meaning to use the card’s CIS
              information to decide.

       mem_speed=n
              Sets  the  access  speed  of  the  shared  memory   window,   in
              nanoseconds.   The  default  is  0 (i.e., no extra wait states).
              Values of up to 1000 are legal.

       delay_output=n
              Specifies that a delay should be  inserted  after  a  polled  IO
              block  output.   This  is  turned  on  by default for Accton and
              Socket EA cards.

       delay_time=n
              Specifies the length of the delay_output delay, in microseconds.
              The default is 4.

       hw_addr=n,n,n,n,n,n
              For  cards whose hardware ethernet addresses can’t be identified
              by the current driver, this is a hack for hardwiring a  specific
              address.   The argument should consist of exactly six byte-sized
              numbers, separated by commas, with no spaces.  Numbers may be in
              decimal or hex (’0xNN’).

DIAGNOSTICS

       pcnet_cs: this is an AX88190 card!
              Indicates  that  this card is based on the Asix AX88190 chipset,
              which requires the axnet_cs driver.

       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.

       eth#: MII is missing!
              Indicates that the driver expects this card to  have  a  ‘‘Media
              Independent Interface’’ for link speed and duplex selection, but
              could not find it.
