PCNET_CS(4) Kernel Interfaces Manual PCNET_CS(4) 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. AUTHOR
