NAME
     ex - Ethernet device driver for the Intel EtherExpress Pro/10 and Pro/10+


SYNOPSIS
     To compile this driver into the kernel, place the following line in your
     kernel configuration file:

           device ex

     Alternatively, to load the driver as a module at boot time, place the
     following line in loader.conf(5):

           if_ex_load="YES"


DESCRIPTION
     The ex driver provides support for Ethernet adapters based on the Intel
     i82595 chip.

     The card will be searched for in the I/O address range 0x200 - 0x3a0.  If
     the IRQ will be read from the EEPROM on the card.  For correct operation
     on newer cards the Plug-N-Play support should be disabled.


HARDWARE
     The ex driver supports the following Ethernet adapters:

     ·   Intel EtherExpress Pro/10
     ·   Intel EtherExpress Pro/10+
     ·   The Olicom OC2220


DIAGNOSTICS
     ex%d: Intel EtherExpress Pro/10, address %6D, connector %s  The device
     probe found an installed card, and was able to correctly install the
     device driver.

     ex%d: WARNING: boardâ€â€™s EEPROM is configured for IRQ %d, using %d  The
     device probe detected that the board is configured for a different
     interrupt than the one specified in the kernel configuration file.

     ex%d: invalid IRQ.  The device probe detected an invalid IRQ setting.
