-.Sh NAME
-.Nm ex
-.Nd "Ethernet device driver for the Intel EtherExpress Pro/10 and Pro/10+"
-.Sh SYNOPSIS
-To compile this driver into the kernel,
-place the following line in your
-kernel configuration file:
-.Bd -ragged -offset indent
-.Cd "device ex"
-.Ed
-.Pp
-Alternatively, to load the driver as a
-module at boot time, place the following line in
-.Xr loader.conf 5 :
-.Bd -literal -offset indent
-if_ex_load="YES"
-.Ed
-.Sh DEPRECATION NOTICE
-The
-.Nm
-driver is not present in
-.Fx 13.0
-and later.
-See https://github.com/freebsd/fcp/blob/master/fcp-0101.md for more
-information.
-.Sh DESCRIPTION
-The
-.Nm
-driver provides support for Ethernet adapters based on the Intel
-i82595 chip.
-.Pp
-On the ISA bus, the card will be searched for in the
-I/O address range 0x200 - 0x3a0.
-The IRQ will be read from the EEPROM on the card.
-For correct operation Plug-N-Play support should be disabled.
-.Pp
-On the PC Card bus, the card will be automatically recognized and
-configured.
-.Sh HARDWARE
-The
-.Nm
-driver supports the following Ethernet adapters:
-.Pp
-.Bl -bullet -compact
-.It
-Intel EtherExpress Pro/10 ISA
-.It
-Intel EtherExpress Pro/10+ ISA
-.It
-Olicom OC2220 Ethernet PC Card
-.It
-Olicom OC2232 Ethernet/Modem PC Card
-.It
-Silicom Ethernet LAN PC Card
-.It
-Silicom EtherSerial LAN PC Card
-.El
-.Sh DIAGNOSTICS
-.Bl -diag
-.It "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.
-.It "ex%d: WARNING: board'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.
-.It "ex%d: invalid IRQ."
-The device probe detected an invalid IRQ setting.
-.El
-.Sh SEE ALSO
-.Xr arp 4 ,
-.Xr netintro 4 ,
-.Xr ng_ether 4 ,
-.Xr ifconfig 8
-.Sh HISTORY
-The
-.Nm
-device driver first appeared in
-.Fx 2.2 .
-.Sh AUTHORS
-.An -nosplit
-The
-.Nm
-device driver was written by
-.An Javier Mart\('in Rueda .
-The PC Card attachment was written by
-.An Mitsuru ISAWAKI
-and
-.An Warner Losh .
-This manual page was written by
-.An David E. O'Brien .
-.Sh BUGS
-Currently the driver does not support multicast.
-.Pp
-The Silicom EtherSerial card's serial port does not currently work.
-The Olicom OC2232 PC Card should work with the
-.Nm
-driver, but is currently completely broken.
