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.

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 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.
