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 signifi-
	      cant 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.
