       pcnet_cs - generic NS8390-based PCMCIA Ethernet Driver


       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]

       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).


              Selects  the  PCMCIA  debugging  level.   This parameter is only
              available if the module is compiled with debugging  enabled.   A
              non-zero value enables debugging.

              Specifies  the  set  of interrupts that may be allocated by this

              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).

              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

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

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

              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.

              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.

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

              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’).


       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.
