device fe
Alternatively, to load the driver as a module at boot time, place the following line in loader.conf5:
if_fe_load="YES"
In /boot/device.hints hint.fe.0.at=isa hint.fe.0.port=0x300 hint.fe.0.flags=0x0
The driver provides automatic I/O port address configuration and automatic IRQ configuration, when used with suitable adapter hardware.
The driver works with program I/O data transfer technique. It gives a fair performance. Shared memory is never used, even if the adapter has one.
It currently works with Fujitsu FMV-180 series for ISA, Allied-Telesis AT1700 series and RE2000 series for ISA, and Fujitsu MBH10302 PC card.
The port parameter specifies a base I/O port address of the adapter. It must match with the hardware setting of the adapter. The port may be left unspecified by removing
hint.fe.0.port="..."from the file. In that case, the driver tries to detect the hardware setting of the I/O address automatically. This feature may not work with some adapter hardware.
The irq parameter specifies an IRQ number used by the adapter. It must match the hardware setting of the adapter. Irq may be left unspecified by removing
hint.fe.0.irq="..."from the file. in that case, the driver tries to detect the hardware setting of the IRQ automatically. This feature may not work on some adapters.
The flags is a numeric value which consists of a combination of various device settings. The following flags are defined in the current version. To specify two or more settings for a device, use a numeric sum of each flag value. Flag bits not specified below are reserved and must be set to 0. Actually, each bit is either just ignored by the driver, or tested and used to control undocumented features of the driver. Consult the source program for undocumented features.
Automatic I/O port address detection feature of works mostly fine for FMV-180 series. It works even if there are two or more FMV-180s in a system. However, some combination of other adapters may confuse the driver. It is recommended to explicitly specify port when you experience some difficulties with hardware probe.
Automatic IRQ detection feature of works reliably for FMV-180 series. It is recommended to explicitly specify irq always for FMV-180. The hardware setting of IRQ is read from the configuration EEPROM on the adapter, even when the kernel config file specifies an IRQ value. The driver will generate a warning message, if the IRQ setting specified in /boot/device.hints does not match one stored in EEPROM. Then, it will use the value specified in the file. (This behavior has been changed from the previous releases.)
Automatic IRQ detection is also available with some limitation. The driver tries to get IRQ setting from the configuration EEPROM on the board, if irq is not specified in /boot/device.hints Unfortunately, AT1700 series and RE2000 series seems to have two types of models; One type allows IRQ selection from 3/4/5/9, while the other from 10/11/12/15. Identification of the models are not well known. Hence, automatic IRQ detection with Allied-Telesis adapters may not be reliable. Specify an exact IRQ number if any troubles are encountered.
Differences between AT1700 series and RE2000 series or minor models in those series are not recognized.

Statistics on the number of collisions maintained by the driver is not accurate; the -i option of netstat(1) shows slightly less value than true number of collisions.
More mbuf clusters are used than expected. The packet receive routine has an intended violation against the mbuf cluster allocation policy. The unnecessarily allocated clusters are freed within short lifetime, and it will not affect long term kernel memory usage.
Although XNS and IPX support is included in the driver, it has never been tested and it is expected to have a lot of bugs.
