    NAME

    skfp - SysKonnect FDDI PCI device
    driver
     
    

    SYNOPSIS

    /dev/skfp   
    
     

    DESCRIPTION

    The skfp FDDI driver is a multi-threaded, loadable, clonable, STREAMS hardware driver supporting the connectionless Data Link Provider Interface (DLPI) over a SysKonnect FDDI PCI adapter. The driver supports multiple installed SysKonnect FDDI PCI adapters. Functions include chip initialization, frame transit and receive, multicast and promiscuous support, and error recovery and reporting.

    The skfp driver supports all SysKonnect SK-NET FDDI PCI adapters (SK-55xx (32-bit) and SK-58xx (64-bit) series) on 32-bit systems, and the SK-58xx series on 64-bit systems.  

    APPLICATION PROGRAMMING INTERFACE

    The skfp driver provides the /dev/skfp cloning character-special device that accesses all SK-NET FDDI PCI adapters using Data Link Service (DLS) Style 2. It also provides per-adapter character-special devices /dev/skfpx, (where x represents the device instance number) that access a special NIC using DLS Style 1.  

    skfp and DLPI

    The skfp driver is a Style 1 and Style 2 DLS provider. All M_PROTO and M_PCPROTO type messages are interpreted as DLPI primitives. Valid DLPI primitives are defined in <sys/dlpi.h>. See dlpi(7P).

    An explicit DL_ATTACH_REQ message by the user is required to associate the opened Stream with a particular device (ppa). This is unnecessary and invalid for DLPI Style 1. The ppa ID is interpreted as an unsigned long data type and indicates the corresponding device instance (unit) number. An error (DL_ERROR_ACK) is returned by the driver if the ppa field value does not correspond to a valid device instance number for the system.

    The device is initialized on first attach and de-initialized (stopped) upon last detach. Valid device numbers for all detected adapters are displayed on the console at driver startup time and written to the /var/adm/messages log file.

    The values returned in the DL_INFO_ACK primitive in response to the DL_INFO_REQ request are:

    * Maximum SDU is 4470.

    * Minimum SDU is 0.

    * DSLAP address length is 8 bytes.

    * MAC type is DL_FDDI.

    *
     SAP length value is -2, meaning the physical address component is followed immediately by a 2-byte SAP component within the DLSAP address.

    * Service mode is DL_CLDLS.

    * Optional quality of service (QOS) support is not included; as a result, the QOS field values are 0.

    * Provider style is DL_STYLE2.

    * Version is DL_VERSION_2.

     

    OPTIONS

    Options are not required for normal operation. In special cases, FDDI Station Management (SMT) parameters can be modified by using the /usr/bin/smtpara utility (see the driver README files). The smtpara utility should be used only by those very familiar with FDDI.  

    DIAGNOSTICS

    If multiple NICs are installed in the system, the following message may appear on the console and in the /var/adm/messages log file:

    skfp: DMA memory allocation failed !

    You can avoid this message by tuning the lomempages kernel parameter. By default, the value of this parameter is 36 pages. Each SK-FDDI PCI adapter requires nine pages, so increase the value of the lomempages parameter in increments of nine pages until all NICs in the system run correctly.

    To modify the value of this parameter to 45 pages, you can, for example, append the set lomempages=45 line to the /etc/system file and reboot the system.
