PC/AT(ISA) version and PC-98(NEC) version of if_fe drivers are merged,
as well as several functional additions. (1) dot3 MIB support. (2) if_media selection method support. (3) bridge support. (4) new boards support. Supported boards are as follows. [PC/AT] * Fujitsu FMV-180 series * Allied-Telesis RE2000 series * Allied-Telesyn AT1700 series * Gateway Communications G/Ether series * UB networks Access/PC ISA series * TDK/LANX LAC-AX series * ICL EtherTeam16i series * RATOC REX-5586/5587 [PC-98] * Allied-Telesis RE1000 series * Allied-Telesis RE1000Plus/ME1500 series * Contec C-NET(9N)E series * Contec C-NET(98)P2 series * UB networks Access/PC N98C+ series * TDK/LANX LAC-98 series(not tested) Submitted by: seki@sysrap.cs.fujitsu.co.jp (Masahiro Sekiguchi) and chi@bd.mbn.or.jp (Chiharu Shibata)

+ * Fujitsu MB86965 JLI mode probe routines.

+ * the chip interfaces with ISA bus with a software-programmable
+ * configuration. (The Fujitsu document calls the feature "Plug and
+ * play," but it is not compatible with the ISA-PnP spec. designed by
+ * Intel and Microsoft.) Ethernet cards designed to use JLI are
+ * almost same, but there are two things which require board-specific
+ * probe routines: EEPROM layout and IRQ pin connection.
+ *
+ * JLI provides a handy way to access EEPROM which should contains the
+ * chip configuration information (such as I/O port address) as well
+ * as Ethernet station (MAC) address. The chip configuration info. is
+ * stored on a fixed location. However, the station address can be
+ * located anywhere in the EEPROM; it is up to the board designer to
+ * determine the location. (The manual just says "somewhere in the
+ * EEPROM.") The fe driver must somehow find out the correct
+ * location.
+ *
+ * Another problem resides in the IRQ pin connection. JLI provides a
+ * user to choose an IRQ from up to four predefined IRQs. The 86965
+ * chip has a register to select one out of the four possibilities.
+ * However, the selection is against the four IRQ pins on the chip.
+ * (So-called IRQ-A, -B, -C and -D.) It is (again) up to the board
+ * designer to determine which pin to connect which IRQ line on the
+ * ISA bus. We need a vendor (or model, for some vendor) specific IRQ
+ * mapping table.
+ *
+ * The routine fe_probe_jli() provides all probe and initialization
+ * processes which are common to all JLI implementation, and sub-probe
+ * routines supply board-specific actions.
+ *
+ * JLI sub-probe routine has the following template:
+ *
+ * u_short const * func (struct fe_softc * sc, u_char const * eeprom);
+ *
+ * where eeprom is a pointer to an array of 32 byte data read from the
+ * config EEPROM on the board. It retuns an IRQ mapping table for the
+ * board, when the corresponding implementation is detected. It
+ * returns a NULL otherwise.
+ *
+ * Primary purpose of the functin is to analize the config EEPROM,
+ * determine if it matches with the pattern of that of supported card,
+ * and extract necessary information from it. One of the information
+ * expected to be extracted from EEPROM is the Ethernet station (MAC)
+ * address, which must be set to the softc table of the interface by
+ * the board-specific routine.
